Chapter Text
-- Thin Places 1: Calibrated --
Sweat trickled down the back of Harry's neck, soaking into the collar of his second-hand shirt.
Ashton Hall towered ahead, all Soviet brick and narrow windows. The building looked like it had been designed by someone who had migrated from eastern Europe and wanted everybody to know it. Blunt. Institutional. The kind of architecture that said "unwanted—you belong here" without needing a sign.
The Dursleys had absolutely loved the brochure.
Dead grass crumbled under his boots; the noise was a satisfying, crunchy kind. The groundskeeper had done a good job in making sure the entire yard was shaved to stubble and rusty yellow.
The main door groaned when he pushed through, and the corridor hit him with its familiar cocktail: deodorant, sweat, and something underneath—old dust, maybe. The kind of smell that seeped into the walls when too many kids spent too many years being miserable in the same place.
Grey lockers lined the hall. Dented. Scratched. The fluorescent lights above them flickered in their usual dying rhythm.
That one.
Third from the corner. The dent was still there, shaped almost like a shoulder. His shoulder, specifically. One of the rare times he had been in a fight.
The bruise had faded. The memory hadn't.
He kept walking.
Laughter echoed from a clubroom somewhere. Gleeful, teasing. The kind of laughter that meant someone was having girl troubles—they were mysterious, with their short-cropped skirts and teasing smirks—remarks about makeup on his—
Don't go there.
Senior year meant different rules. Meant his own room. Meant being left mostly alone by hyenas who'd moved on to easier targets.
Small mercies.
The stairs were empty. He took them two at a time, legs moving on autopilot while his mind wandered somewhere darker. The dreams had been bad last night. Hooded figures. Screaming. The same images that had plagued him for as long as he could remember.
His room waited at the end of the hall.
The door clicked shut behind him and Harry exhaled. Let his shoulders drop. Let the mask slip, just a little.
Quiet.
Grey light filtered through heavy curtains, painting everything in muted tones. Metal desk. Narrow bed. Mattress that sagged in the middle.
Home.
The word didn't fit, but he'd stopped looking for one that did.
He dropped into the desk chair—familiar creak, almost comforting—and his spectacles slid down his nose. Cracked lens. Held together with tape. He pushed them back without thinking.
The notebook was where he'd left it. Open. Waiting.
Dark lines covered the page. Darker shapes.
Someone might call them abstract. Art therapy, a book had suggested once. Creative expression. As if there was anything creative about trying to trap nightmares in graphite before they ate you alive.
The hooded figure dominated the center. Bodies at its feet. Masked followers fanning out behind.
Harry didn't remember drawing most of it. That was the worst part. His hands moved while he slept—or didn't sleep, couldn't tell anymore—and in the morning there they were.
The sleep brought them in.
Faces he didn't recognize. Screams he couldn't unhear.
He pressed his palm flat against the paper. Hard.
Stop.
The pencil slipped from his fingers and clattered to the floor. He let it lie.
Drawing doesn't help.
He should sleep more. He should brave the nightmares. Not… he swallowed the feeling choking him—not just try to get better.
He'd known that for years. Kept doing it anyway. Some part of him hoped that if he weathered it all out like a bad storm, the dreams might finally stop.
They never stopped.
He shuddered once—sharp, involuntary—and pulled back. Enough. Enough of that.
The radio was still on his desk. Gutted. Backplate missing. Someone's garbage, tossed in the bin.
Like you.
The thought came unbidden and he shoved it away. Not helpful. Not now.
He pulled the radio closer instead. Something to fix. Something to distract. Circuits didn't care about your nightmares. They either worked or they didn't, and if they didn't, you could find the fault and correct it.
Simple. Clean. Sane.
The lamp angled until solder joints became tiny moons. Dust clung to everything. He reached for the brush—better than blowing, less risk of spit—and whisked the grey fluff away in careful strokes.
Nothing obvious. No scorch marks. No exploded capacitors.
He prodded the battery contacts. Greenish crust flaked away under his fingernail.
Corrosion.
There you are.
Something in his chest loosened. A problem with a solution. A thing that could be fixed.
The vinegar was in his kit. He reached for it, almost smiling.
Some things, at least, still made sense.
It didn't take long to clean the corrosion—yet as he placed the tools aside—the books on his nightstand caught his eye: A Game of Thrones, and Slave to Darkness.
Gems from the local library, he would continue delving on them later today. But now—there was work to be done.
He fetched a multimeter from a bottom drawer.
Battery to switch. Switch to regulator. Regulator to the little cluster of chips that kept time. He touched the probe to each pad, listening for the meter's tiny chirp. It sang where it should, then fell silent one step too early.
He leaned closer. Under the magnifier, a solder joint by the power input wasn't smooth like the others. It had a faint ring around the pin, a hairline fracture you'd miss if you weren't looking for it. Cold joint. A single point of failure pretending to be whole.
He heated the iron until it breathed a thin, metallic warmth. A dab of flux, the sharp pine-sweet smell rising. The solder softened, flashed silver, and flowed again, sealing the ring into one clean dome.
He let it cool, then pressed the batteries in.
The speaker crackled. A red LED blinked awake.
Another salvage rescued.
Next, he set the time: 16:12. He noticed the minute roll over to the next, lazily. He should add new batteries.
"Achoo!" He sneezed from all the dust particles, they were drifting lazily inside his small room.
There was something in the air that was not quite out of place to say... But something seemed to escape other people's attention. Like a hum or a mirage of energy, that only he could sometimes see and feel, and shape.
Not dust. Something else. A hum beneath the silence. A shimmer at the edge of things that vanished when you looked directly at it.
He'd felt it his whole life. That pressure behind his eyes. That sense of more lurking just beneath the skin of the world.
Other people didn't notice.
He'd checked. Carefully. Years of watching faces for recognition that never came. Years of waiting for someone else to say, do you feel that?
No one ever did.
So, he'd gone looking for answers.
The library first. Section 130—parapsychology, ESP, the occult. He'd worked through the shelf systematically, taking notes in a journal he kept under the loose floorboard. Auras. Chi. Quantum consciousness.
None of it fit.
It wasn't anything from his books. It was something entirely different.
'I'm crazy.'
Harry pushed back from the desk and caught his reflection in the bathroom mirror.
There you are.
Emerald eyes – too feminine. Almost hidden behind a curtain of dark mass. Facial profile as always oozed frailness, the pig—no—Dudley often ridiculed him for 'girliness'.
He'd learned to avoid eye contact. Kept his gaze down. Let the dark curtain of hair fall forward.
Camouflage.
His cheekbones caught the grey light. Sharp. Fine. The kind of bone structure that showed up in fashion magazines—women's fashion magazines.
His jaw should have squared by now. Thickened. Roughened with stubble that needed shaving.
It hadn't.
He reached for the comb. Cheap plastic. Teeth missing. His fingers worked through tangles automatically—
A strand slipped free and paled.
Black to grey. Grey to white. Winter white.
"No—"
He clamped down. The muscle behind his eyes, the one he couldn't name. He pushed.
Grey to dark. Dark to black. Safe.
His hands were shaking. He gripped the sink until they stopped.
No one must know.
His back still remembered Uncle Vernon's heavy belt. The beating after his hair had turned blue.
Fear taught control.
He'd considered coming clean once. Imagined stoic scientists who would explain everything.
Then imagined government labs. White rooms. Needles.
He shook off the thought.
The books hadn't helped. Faceless men came closest. Psykers, maybe.
Still wrong. But entertaining reads nonetheless—the Warhammer universe was fascinating.
He tucked the white strand away, hidden in the dark mass. Checked the mirror one last time.
Shaggy hair. Shadowed face. Oversized shirt.
Normal.
Good enough.
Everything needed to be ready for Surrey. But first, Jack had a plan—and Harry had promised to tag along.
✦ ✦ ✦ ✦
Jack was in another of his "strokes of degeneracy," scheming to undress his latest crush. Harry had been drafted as wingman.
Harry cut through the rundown end of the suburb: paint-peeled fences, empty windows, a rusted streetlight buzzing like a trapped insect. Beneath it, Jack flicked away his cigarette.
"Fucking finally," he rasped.
A denim jacket hung loosely on Jack's frame; wind pushed blond hair into his eyes. He looked ordinary enough, but he was anything but.
"Sorry I'm late – too busy snogging your girlfriend."
"Yeah, right. She's into guys." Jack ground the butt under his boot.
A low blow. He buried the impulse to snap back and kept his face blank. "Think you'd meet them?"
"Please. Now come on."
Jack led the way, eyes skipping from house to house until he stopped before a sagging, lemon-painted relic. "This one."
Once, Harry figured, that cheery siding had framed a catalogue fantasy – neat kids posing for photos, a golden retriever sealing the postcard. A life he'd begged for, once.
Now he knew better.
The yard oozed ruin, and the sight gave him a spiteful spark of pleasure. The picket fence had gone dull grey with mould; the dog, he guessed, lay somewhere under the dead grass.
Jack edged towards the porch, shoulders tight. In a horror flick, Harry decided, Jack would die early – and for something stupid.
An uncomfortable chill clung to the yard, though the summer sun blazed on their necks. No warmth reached their skin. Ash-grey soil looked starved – as if waiting for new bodies.
Jack affected nonchalance, but the tilted door sagged on a single hinge when he nudged it.
"Well… At least it isn't locked." The door groaned open, its protest echoing through the house.
Dust-thick air swallowed Harry as he stepped inside. Thin light seeped through cracked panes, bleaching the corridor a sickly grey. Wallpaper – once ornate – hung in ragged strips; the floorboards rattled under every cautious step. The place felt wrong – it was watching their every step.
Don't rouse the slumbering beast.
Gloomy light picked out broken furniture and dust-caked portraits, paint flaked as they swung crooked on their hooks.
Jack's confident stride ate up the creaks. Harry's heart thundered in response.
They ventured deeper, passing through a once-elegant living room, its fireplace choked with ashes. Cloying fungal stench welled around them – seducing them further in – wrapping them up.
A sudden sound made him freeze.
Something inside the walls.
Jack wiped dust from the photo; his smile fell, the frame recovered its resting place.
They tumbled into the dining room. An overturned table thrust its legs skyward, pleading. The kitchen counter lay broken, beads of water bled from a hole in the ceiling. Drip-drip-drip filled the silence.
The rusty chairs were of stronger make than they appeared. Jack cautiously lowered himself on one, rust flakes shedding like snowflakes. He struggled with the light for a moment, grunting as the flame finally licked the fag; Harry mirrored the motion, sparks dancing off tilted grimy floorboards.
"You reckon the Thompsons could salvage this?" Harry nodded at the sludge-covered sink.
"Throw me a couple grand and I'll make this place livable for ya."
"Still better than at the Dursleys'."
"I'm surprised you haven't murdered them yet." Jack guffawed.
Sometimes he wondered that himself. He could take starvation, the beatings, the repeating insults; maybe he really was soft and girly. Still, this was the last summer at Privet Drive, and jail time didn't appeal at the end of the tunnel.
The short silence was filled with creaking wood and puffs of smoke – occasional cough.
Amidst the debris, Jack's eyes caught something—a faint outline on the floor, obscured by an old, moth-eaten rug.
Jack grunted and shoved the waterlogged rug away; it slapped the floor, revealing a hatch carved flush with the planks.
His eyes glittered. Too excited.
No way I'm going down there.
"This is it," Jack whispered, voice low. A metallic scrape rang out as he nudged the hatch open. A fetid draft hissed up from the blackness.
"I'm not going down there," Harry murmured, stomach tightening. He peered into the abyss; no bottom in sight.
"Trust me, it'll be fine." Jack grinned.
✦ ✦ ✦ ✦
The flashlight swept a pale cone across the concrete.
Cobbled stone paved the ground; his shoes thumped distractingly loudly against it as they landed.
Harry dropped onto white stone and felt his legs steady. Solid ground. A relief after the balancing act on rotting wood of the entrance.
Jack agreed with a grunt as he stretched gloriously next to him.
"Not bad, huh?"
Harry didn't answer. His eyes were adjusting.
Walls. Ceiling. Floor. All concrete—smooth, almost pristine. Like it had been poured yesterday.
Bomb shelter, maybe. Or something else.
Despite the effort put in smoothening and crafting the narrow corridors, the entryway smirked with emptiness.
Not entirely deserted.
A faint sound reached him.
Haunting. Fading.
Tapping, and scraping, like nails against stone.
The hair on Harry's neck stood up. Something cold slithered down his spine and settled in his gut.
Get out. They should get out.
He glanced at Jack.
Jack was shuffling. Weight shifting foot to foot. His neck tight.
He's afraid?
That was—
That was strange. Jack was never afraid. Jack bulldozed straight into an abandoned mental asylum at midnight and laughed about it. Jack didn't shuffle like this, he just didn't.
"Ya know…" Jack's voice came out rough. He cleared his throat. "Don't go talking about what ya see next, yeah?"
"…Ok?"
Jack reached into his denim's breast pocket.
Pulled out a stick.
A stick.
Wooden. Thin. About the length of his forearm.
Jack glanced around—checking the shadows, checking the corridor behind them—and then his wrist flicked. A contained, precise motion, like he'd done it a thousand times.
"Homenum Revelio."
What—
Something prickled against Harry's skin.
A wave of—of something. Phantom tickles crawling up his arms, across his scalp, raising gooseflesh in their wake.
He knew that feeling.
He knew that feeling.
✦ ✦ ✦ ✦
Spring.
Halogen beams skittering across cracked tiles. Jack smashing through the glass panel. The door groaning open.
Straitjackets lining the corridor. Stained. Stiff with dried fluids.
Syringes on a steel tray, needles rusted and crooked.
Footsteps too loud. His throat clenched tight. A soft scuff behind him—
No one there.
The director's office. Files scattered across a dusted desk. SUBJECT 0201 — Serum XTOH, 15ml (diluted). Heart palpitations. HRV: sympathetic surge. TEST: FAIL.
A ragged breath past his ear.
Jack's voice low: "Increased dosage…"
Dread crawling up his spine, like something alive.
✦ ✦ ✦ ✦
Harry blinked.
Back to the concrete. The silence. The dark.
An uncomfortable poison crept throughout Harry.
"It seems like we're all good," Jack exhaled, his posture loosening.
Harry's hand found Jack's sleeve. Grabbed the denim. Held.
"Can we leave?"
His voice echoed down the empty hallway. Too loud.
Jack turned.
There was something wild in his eyes.
Shit.
"We are just getting started, Harry!" His voice was all too bright.
Harry's stomach clenched hard. Shadows shifted at the edge of the flashlight beam—moving, crawling, salivating—
"I don't like this place." His voice was harder than he meant. "At all."
Please, for once don't be like this.
Jack laughed. Muffled. Short.
"You say that every time."
His face was half-shadow, half-light. Only the curve of his smirk visible, lit from above like something from a horror film.
"Tommy and Lisa said that this place was haunted. Of course we need to check it out."
And there he went.
Jack took the lead, his steps summoned clouds of dust that hung in the air like unholy Christmas decorations.
He muttered something under his breath.
Light. Actual light—soft, white, steady—pouring from the tip of the stick.
…More bullshit?
"What is that?" Harry's voice cracked. "Jack—what the hell is—"
"Don't freak out."
Don't freak out?
"We'll talk about this later."
Later?
He was holding a bloody glowing stick—elm—an elm stick—that was glowing. And he was telling him not to—not to freak out? With a glowing wooden stick?
His mouth had opened at some point; he closed it with a clack of teeth.
Later. Fine! Later…
He followed.
✦ ✦ ✦ ✦
The basement stretched.
And stretched.
And kept stretching.
Corridors branched off like arteries—left, right, left again—each one leading somewhere deeper, somewhere darker. The architecture didn't make sense. Too much space for a building this size.
Cardboard boxes scattered the floor. Black electrical wiring snaked across the concrete—Harry watched his feet, stepping over and around.
The skittering of rodents faded.
The tapping stopped.
Silence.
Worse. Somehow the silence was worse.
Every step felt like something was dragging them deeper into a swamp. Taking something. Something draining from his chest, leaking out through the soles of his feet into the hungry concrete.
Bad place. Bad place. Bad place.
The path split.
Left: a stairway descending deeper into the earth. Harry aimed his flashlight down it. The beam seemed pathetic—swallowed after a few meters, consumed by the darkness.
Right: another corridor. Flat. Stuffy. Concrete walls pressing close.
Jack pointed his wand at the right-hand passage. The magical light reached further than Harry's flashlight—but even that was being eaten. Devoured.
"This doesn't feel right."
Harry heard his own voice like it belonged to someone else.
"It's just a basement, Harry."
"I have a bad feeling."
The words felt insufficient. Dull. Stupid. The kind of thing people said in telly before everything went to gutter.
But it was more than that.
His other side felt it.
Dudley and the rest of the shitty drug-dealing lot had been so convinced that Harry had pinched from them.
A baggie of white powder hidden in his backpack. "A jest." Something to get him arrested, expelled, destroyed.
There had been a feeling that day. A nagging in the back of his skull. Something wrong. Like a key forgotten. A stove left on.
When he'd seen the police at Privet Drive through his window, he'd finally listened.
He'd found the drugs in time.
The feeling was back now.
Stronger than ever.
Worse than when he had almost been run over by a bus.
Worse than when a dark-cloaked man had wandered the street a block away from Ashton Hall, searching.
Searching for me.
Another corner.
More darkness.
Endless.
"Homenum revelio," Jack murmured. The wand flickered.
The prickle again. Phantom fingers across his skin.
"Jack."
"What?"
"There is something in there."
"There is nothing!" Jack snapped.
A bead of sweat rolled down his narrow face.
You feel it too.
You feel it and you won't admit it.
Scrunch.
The sound came from deeper in the corridor.
Echoed off the damp concrete. Crept closer.
Multiplied.
"Jack, listen—"
Harry's voice was barely a breath. His heart hammered against his ribs—a panicked animal throwing itself at the bars.
His ears strained into the darkness.
Don't listen.
Don't—
Scrunch. Scrunch.
Tap. Tap.
"Something's coming."
Raw whisper. Panic gripping his throat like a shackle.
SCRATCH.
The flashlight beam caught something.
Glistening.
A form at the edge of the light. Swaying left, right, left—like a broken pendulum. Like something that had forgotten how bodies were supposed to move.
Harry's hand froze.
The light froze.
Everything froze.
And then the darkness lifted.
No.
No no no no—
It had been human once.
The thing standing in the corridor had been human once.
Pallid skin stretched over bones—too tight, too thin, translucent in places. The skeleton showed through like shadows under ice. The flesh that remained was mottled grey-green. Patches sloughed off as it moved, revealing dark wet tissue beneath.
Its eyes—
Don't look at its eyes.
Rotten. Gone. Just dark smudges in the skull where eyes should be.
But it saw them anyway.
He could feel it seeing them.
Focused. Precise.
Hungry.
I know this.
The thought came from somewhere deep.
Somewhere older than memory.
I've seen this before.
Creeping laughter.
Green light.
Torture. Gore. Ritual.
Atrocities summoned from the most terrible sins.
The flashback shattered.
Harry was here. Now. Staring at something that shouldn't exist outside his nightmares.
This can't be real.
This can't—
The creature's mouth opened.
What came out wasn't a sound.
It was a violation.
Sharp. Scraping. A nail dragged across the inside of his skull. A pig being slaughtered. A child screaming through a throat full of broken glass.
Harry's flashlight stuttered. His hands—traitors—were shaking so hard the beam danced across the walls like a dying thing.
Jack's wand-light flickered.
Died.
One flashlight now. One stuttering beam between them and the advancing corpse.
Move.
MOVE.
"REDUCTO!"
Jack's scream shattered the trance.
Something red streaked from the wand—vivid, fast, violent—and struck the creature dead center.
The effect was—
Shotgun.
Muffled splat. Red flash.
The thing exploded.
Decayed flesh painted white concrete in a wet spray. Chunks. Fragments. Things Harry didn't want to identify.
The lower half stayed standing for one horrible moment—stitched together by rot and momentum—then crumbled.
Dead.
It's dead.
It's—
Flapping.
Scratching.
The sounds came from deeper in the corridor. Multiplying. Building.
More glistening forms in the darkness.
More.
Jack's eyes found his.
A thousand words in that look.
I'm sorry.
I didn't know.
We have to go.
NOW.
Harry nodded.
"RUN!"
They ran.
✦ ✦ ✦ ✦
The left pathway called him—
Magnetic pull from somewhere deep inside his chest.
He chose it—leading Jack by the fabric of his sleeve further down into the earth.
"WHY ARE WE GOING DOWN?" Jack shouted at him.
"I've got a good feeling about this path!"
"FEELING?! WE NEED TO GO BACK!"
Mad scramble, pulse thundering in his ears, corridor after corridor flew past them.
Jack flicked more red lights to the darkness behind them.
He didn't dare peek. Didn't want to fall.
Just run.
Left and right turns mixed together, like a wet fever dream. Light bouncing up and down—black cable ready to trip him—jump!
He jumped.
Tension in the muscles, air burning his lungs, feel of smoothly laid concrete under his palms when he pushed against sharp curves.
This was real.
Not a nightmare.
The feeling was going haywire in his chest—guiding him—guiding them to safety.
They stopped.
They were stopped.
A giant door blocked their path.
Jack bent double, wheezing. Too many cigarettes. Too much running.
The silence behind them had come back. No more scratching. No more sound of slithering flesh against flooring—
Don't think.
The new silence urged them forward.
Tk.
Tk.
Tk.
His own footsteps. Bouncing off stone.
The obstacle was clearer now.
Mahogany.
The word surfaced from somewhere. Woodworking class.
It was a bloody antique mahogany door.
Just standing there in this concrete nightmare. Beautiful in a way that made his chest tighten. But—
What kind of lunatic brings something like that underground?
He edged closer. Hand outstretched.
His fingers found grooves. Traced them before his mind caught up.
The wood felt warm—too warm, almost like skin, and something in him shivered with pleasure at the texture.
Carvings. Intricate ones. Six-pointed stars adorned each corner, their centers carved with symbols that looked obscene.
Clawed hands reached across the surface in languid, sensual poses. Serpents coiled around roses, their scales polished smooth, almost inviting to touch.
Harry's fingertips lingered on one carved figure. The limbs seemed too numerous, the pose too fluid, too... alive. His head felt light. The carvings promised… Pleasure… Pain... Both.
He shuddered and pulled his hand back.
There was writing on the edges. A flowing script, the letters elegant.
"I can be gentle; I can be rough.
Your body will be my playing field sure enough.
Misery and hurt just an afterthought.
Naught will cure the memory so distraught.
What am I??"
It was a riddle.
The air in the corridor was heavy, damp with the scent of mold and old stone prickling on his nose.
Tapping.
Distant. Rhythmic.
Familiar.
They're coming.
Jack pressed close, reading the riddle. His lips moved without sound.
The corridor felt smaller. More constricting.
"PTSD?"
Jack's voice cracked high.
"Murder?"
Sweat darkened his collar. Dust caked his face.
"War?"
Tap. Tap. Tap.
Closer now.
"I DON'T FUCKING KNOW!"
He threw himself at the door. Shoulder first. The mahogany didn't budge an inch.
Again.
Again.
Nothing.
A bead of sweat trickled down his temple.
He turned. Flashlight up.
The corridor behind them—
Empty.
For now.
The walls inched ever closer.
Tap. Tap. Tap.
People stuck inside the concrete. Bloody fingers drumming the stone—
Stop.
Think.
I can be gentle, I can be rough.
Your body will be my playing field sure enough.
Jack's guesses echoed. PTSD. Murder. War.
Close, but not quite… 'gentle', 'rough', and 'body'… it is more personal.
TAP. TAP. TAP.
Misery and hurt just an afterthought.
Naught will cure the memory so distraught.
The second half of the riddle rang inside his skull.
Needs to be intimate, but something gentle that can hurt—
"Rape"
The words slithered out his mouth unbidden.
Violent.
Like speaking it was committing the act itself.
Click.
The door swung open.
Move.
They scrambled through. Harry's hands found the edge—slick with sweat, slipping—and he hauled it shut behind them.
SLAM.
Silence.
His breath came ragged. Jack's came worse.
Safe.
Maybe.
He turned.
One last look at the door. At the carvings that had pulled at something in his chest. The serpents. The clawed hands in their languid poses.
Wait.
His stomach dropped.
The serpents had turned. Wooden eyes fixed on the exact spot where he stood. Mouths curved into smirks.
They're watching me.
They're watching ME.
The door was just wood. Just mahogany and old carvings.
That's what he told himself.
✦ ✦ ✦ ✦
Stale air hit him first, then dust—a cloud of it disturbed by the door, swirling slow in light that had no source.
Harry held his breath.
The room beyond was wrong.
Not obviously wrong. Not screaming-corpse wrong. Something subtler. Something that crept in through the eyes and settled in the base of his skull like the beginning of a fever.
A laboratory. That was the word for it. Workbenches cluttered with glass instruments—alembics and retorts and spiraling tubes that caught the strange light and held it. Cabinets stuffed with vials in colors he couldn't name. Yellowed parchment stacked in towers that seemed to breathe, to shift, when he wasn't looking directly at them.
Old books. Stale chemicals. The smell of places where people had done things they shouldn't.
Then his senses caught the rest.
Sweet.
The air was sweet—too sweet, honey rotting into something thicker, clinging to the back of his throat like syrup. It coated his tongue. Crawled into his sinuses. Made his mouth water and his thoughts slow, and somewhere beneath the disgust there was something else.
"Christ." He covered his nose with his sleeve. It didn't help. The sweetness was inside him now, seeping into his blood, making his limbs feel heavy and his head feel light.
Braziers crouched in the corners like sleeping animals. Purple smoke rose from their mouths in lazy spirals, forming shapes that his eyes refused to hold—curves and coils and something that might have been bodies, might have been limbs intertwined, might have been nothing at all.
He looked away.
The shapes followed him, burning in his peripheral vision like afterimages of the sun.
What happened in this room?
The thought surfaced through the haze, sluggish and unwelcome. He didn't want to know. Could feel the answer pressing against his awareness like something trying to get in through a locked door.
Rituals.
This was a place for rituals.
Jack was staring at him.
"Are you a metamorphmagus?"
"A what?"
"Your hair. It's white."
FUCK.
His hand was halfway up before he stopped it—the old give-away, the flinch toward the hairline, the thing that told anyone watching that yes, he knew, yes, it did that. He turned the gesture into pushing his fringe out of his eyes and looked at a strand as it fell back. White. Bone white, root to tip, the way it went when the fear got in under everything before he'd even noticed it arriving.
He fought back the control.
It was an old fight and he knew the shape of it: not forcing, forcing never worked, forcing just made it slide from white to grey to something worse. You had to do the other thing—the trick he'd taught himself at six or seven under the stairs, after the last time it had gone red at the dinner table and the shouting had lasted an hour. You went small inside. You found the picture of yourself the way you were supposed to be, ordinary, black-haired, unremarkable, the boy nobody looked at twice—and you held it, the way you'd hold your breath, until the picture soaked back down through the scalp like water into dry ground.
Warmth crawled across his head. He felt it happen—he could always feel it happen, a prickling wave running back from his forehead—and knew without a mirror that the black was coming back in.
"Trick of the light," he said. "It's the smoke."
Jack squinted at him for a second longer. In any other room he wouldn't have bought it—Jack wasn't stupid—but the sweet air was in him too, blunting the edge of things, and Harry could see the question lose its footing and slide away half-formed.
"Weird light in here," Jack agreed vaguely, and turned back to the room.
Harry breathed out, slowly, through the sweetness.
He hated it. He'd hated it his whole life—the hair, the tell, the way his own head informed on him to anyone who happened to be looking. He'd learned to keep it down the way you learned anything under that roof: badly at first, then well, then so well it was almost automatic. Months went by now without a slip. It took something real to crack the hold.
Something in this room was real, then. That was worth knowing, even if he didn't want to know it.
Jack moved past him, oblivious, already examining the nearest workbench. His fingers traced instruments with casual familiarity—the ease of someone who had seen such things before, who knew their names and uses.
"Standard stuff. Scales, measuring equipment, notation—" He paused, frowning. "Huh."
"What?"
"Nothing. Just weird handles on these scalpels."
He didn't ask what made them weird. The sweet air was doing something to his thoughts, softening their edges, making it hard to hold onto questions. Jack flowed through the space as if through water, his movements trailing behind him in the strange light.
He doesn't feel it.
Why doesn't he feel it?
The floor was ancient stone—slabs worn smooth by feet that had walked here long before concrete existed, before the city above had been built, before anything Harry knew had names. His shoes made soft sounds against them as he moved deeper, drawn forward by something he couldn't identify.
A pillar rose from the center of the space, stretching up into shadows that seemed to breathe. Harry circled it, one hand brushing the stone, and his fingertips came away warm.
Stone shouldn't be warm.
Nothing down here should be warm.
But everything was. The air. The light. The sweet haze that filled his lungs with every breath. The room itself seemed to pulse with something like life, something like hunger, something that had been waiting a very long time for someone to open that door.
His thoughts fragmented.
Underground maze. Cement over ancient stone. Corpses that walked. Jack's wand—wand, that was a wand, that was magic—words in Latin that killed. The door that watched him.
Who built this?
Why?
What were they trying to do?
His neck was wet. Sweat pooling in the hollow of his throat, soaking into his collar. The sweet air pressed against his skin like hands, like dozens of hands, gentle and insistent and wrong.
Can't breathe.
Can't think.
Can't—
His back found the pillar. He let it take his weight, let himself slide down the warm stone until he was sitting on the floor with his knees drawn up and his head swimming in honey-thick fog.
"Harry?"
Jack's face materialized from the haze. Face scrunched—worried. Smudged with ash.
He held out a cigarette.
Harry took it with fingers that felt like they belonged to someone else. The smoke burned his lungs—familiar pain, grounding pain—and for a moment the fog thinned enough for him to think.
The air is drugged.
Something in the air is drugging me.
But even that thought slipped away, replaced by the sweetness, by the warmth, by the strange contentment that wanted to settle into his bones and never leave.
Jack was talking. Harry heard fragments of his voice carry through the fog of something clouding his mind.
"—too close—"
"—look at this place—"
"—we can sell—"
The words didn't connect. Just sounds, drifting through syrup, meaningless.
Then something shifted.
The fog didn't lift—it never lifted, not entirely, not while he was in that room—but something underneath it hardened. Some core of himself that refused to dissolve.
Answers.
I want answers.
He moved before the thought finished forming.
Jack's back hit the wall. Harry's fist was in his collar, rough denim under his knuckles, their faces inches apart. The world swam around them but this was solid, this was real—the fabric in his hand, the surprise in Jack's eyes.
"Now." His voice came out strange. Thick. Like speaking through honey. "Tell me what the fuck is going on."
Jack's throat worked.
"I can't—there are rules—"
"Rules?"
The word tasted like poison.
"Yeah." Jack's voice was small. "Later."
Harry released him. Stepped back. The fog rushed in to fill the space where his anger had been, but something remained. Some splinter of cold clarity lodged in his chest.
I will get answers.
One way or another.
✦ ✦ ✦ ✦
They moved deeper.
The chamber opened into something larger. The ceiling vanished into purple shadow that seemed to pulse with the rhythm of Harry's breathing. Or maybe he was breathing with it—matching his lungs to the room, becoming part of whatever ancient thing lived in these walls.
He couldn't tell anymore.
A pedestal waited at the center of the space.
Waited.
The word was right. Harry felt it in his bones—this altar, this offering stone, this place where things had been given and taken. It had been waiting for a very long time.
Two objects rested on its surface.
One was a bottle—small, ornate, filled with liquid that shimmered like captured sunlight. Beautiful in the way fire was beautiful. In the way poison could be beautiful.
The other was metal.
Copper-colored rings interlaced, forming a sphere no larger than his fist. Something lived inside it—pulsed inside it—a slow rhythm like a heartbeat seen through murky water.
The surface was carved with symbols.
Harry looked at them directly.
They were still.
He looked away.
They moved.
Crawling at the edge of his vision. Rearranging themselves into patterns his mind refused to parse. Six-pointed stars. Figures in poses that made his stomach clench.
Don't look.
Don't—
He looked.
Jack's voice came from somewhere far away, excited about the bottle, saying words like "Felix Felicis" and "worth" and "serious find." None of it mattered. None of it reached through the fog to where Harry stood, his eyes locked on the sphere, his hand rising without his permission.
What are you?
The artifact seemed to pulse faster.
Answering.
His fingers hovered over the carved surface. Close enough to feel heat radiating from the metal—not warmth, heat, like touching a sun that had learned to be cold.
Don't.
He touched it.
✦ ✦ ✦ ✦
The world ended.
Not with sound. Not with light. With sensation—a jolt of pure electricity that lanced through his arm and detonated in his skull, scattering his thoughts like birds startled from a wire.
His hand locked around the sphere.
Can't let go.
Part of me now.
I'm—
Buzzing.
It started in his fingertips. Spread up his arm. Crawled across his chest like a living thing, like something burrowing into his flesh, making its home in the spaces between his cells.
Then it reached his brain.
Particles.
The word surfaced from somewhere—from the artifact, from himself, from the place where those two things were rapidly becoming indistinguishable.
Thousands of particles rearranging.
He could feel them. Could feel his own neurons bending, stretching, connecting in patterns that had never existed before. Something new being built in the architecture of his mind. Something permanent.
This won't undo.
This is forever.
His vision blurred. The room spun—colors smearing, shadows stretching, Jack's distant face dissolving into light and darkness and the shapes between.
"Harry?"
So far away.
He's so far away.
Everyone is far away.
I'm—
I'm—
Fabric scraped against his skin.
His shirt. Just his shirt—but every thread was a wire, every fiber a razor, every point of contact an explosion of input his brain didn't know how to process. He could feel the weave of the cotton. Could count the threads. Could trace the path of each individual strand against nerve endings that had never felt anything so clearly.
Too much.
The floor pressed up through his shoes. Weight. Gravity. The specific angle of his bones against the stone.
Too much.
The air painted itself across his tongue. Sweat. Dust. The sweet corruption of the room. And underneath—the specific chemical signature of Jack's fear, of his own adrenaline, of the incense long since burned away.
Too much.
Colors exploded. Every shade splitting into components, into wavelengths he could almost hear. Dust motes hung frozen in the air—each one a crystal catching light, refracting it, showing him spectrums that shouldn't exist.
I can see the dust.
I can see between the dust.
I can see—
Sound.
Jack's breathing was a thunderstorm. His heartbeat was a drum, visible in the pulse at his throat, pounding through the air in waves Harry could almost touch.
Everything is more.
I am more.
I—
His thoughts accelerated.
Bouncing through his rebuilt mind at speeds that shouldn't be possible, each one fragmenting into a dozen others, each of those spawning more, multiplying like cells dividing, like fire spreading, like something being born in the wreckage of what he used to be.
Escalating—
Escalating—
Escal—
Stop.
Silence.
Harry gasped.
His lungs remembered how to breathe. His hand was still locked around the sphere—he couldn't have dropped it if he wanted to, it was part of him now, fused to his palm at some level deeper than skin—and the warmth pulsed against his flesh in a rhythm that matched his racing heart.
The same.
We're the same now.
"I..." His voice cracked. Broke. "I don't know what just happened."
Jack was staring at him. Pale beneath the grime.
"That thing did something to you."
Yes.
"Are you alright?"
No.
"Yeah. I think so."
The lie tasted like copper. Everything tasted like something now—his own words had texture, had weight, had colors at their edges that he'd never seen before.
Changed.
I'm changed.
Forever.
The artifact pulsed in his palm. Warm. Patient. Satisfied.
Harry looked down at it—at the copper rings, at the symbols that still crawled when he wasn't watching—and knew with absolute certainty that he would never be able to put it down.
Not because it wouldn't let him.
Because he wouldn't want to.
✦ ✦ ✦ ✦
They searched the shelves. Found dust. Found blank pages where words should have been. Found nothing that explained what this place was, who had built it, what they had done in the purple dark with the sweet air and the watching shapes.
Erased.
Someone erased it all.
But they'd left the artifact.
They left YOU.
Harry tucked the sphere into his pocket. It settled against his thigh like something coming home. The warmth bled through the fabric, pulsing in time with his heart, and his new senses sang with the contact.
Part of me.
You're part of me now.
The walk out was a blur. Corridors. Stairs. Sunlight that hit his eyes like a physical blow. Jack's voice making him promise things—silence, secrecy, the usual terms of their unusual friendship.
Harry agreed to everything.
His mind was elsewhere.
His mind was everywhere—noticing the cracks in the pavement, the specific blue of the fading sky, the chemical composition of the air above ground, the thousand thousand inputs his brain was suddenly equipped to receive.
This is what it's like.
This is what I am now.
✦ ✦ ✦ ✦
Evening.
His room. His desk. The lamp casting shadows that his new eyes could trace to their sources, could measure, could understand in ways he never had before.
The artifact turned in his hands.
Fading.
There were fewer rotating rings now.
Still.
It was beautiful.
Copper rings sliding over each other in patterns that were almost mesmerizing, almost obscene, almost meaningful. The symbols caught the light and held it. His fingers traced them—over and over—feeling the way they connected, the way they meant something just beyond his reach.
What are you?
No answer. Just warmth. Just the pulse that matched his own.
He should pack. The Dursleys expected him. Surrey waited.
He kept tracing the symbols instead.
His fingertips tingled. His vision stayed sharp—sharper than it had any right to be, picking out dust motes and fabric threads and the hairline cracks in his ceiling.
This is permanent.
This won't fade.
The artifact will.
The thought should have terrified him.
It didn't.
When he finally set the artifact down to sleep, the absence hit him like a blow. Like reaching for a limb and finding empty air. Like a silence where sound should be.
Missing.
I'm missing.
He picked it up again.
The warmth returned. The pulse synchronized. His rebuilt nervous system hummed with something that might have been contentment, might have been completion, might have been the first step of a journey he couldn't yet imagine.
What did you do to me?
The artifact didn't answer.
But it stayed warm in his hand through the night, pulsing in time with his heart, and when Harry finally slept his dreams were full of copper light and shifting symbols and the sweet, dark certainty that nothing would ever be the same.
