Summary
And in the midst of it all, he thought one, gruelling thing:
He was just like Eclipse.
That thought caused him to stop in his path, mind going oddly fuzzy as his thoughts cut out, head turning towards the alleyway once more, speedwalking over to it.
And he stared.
Stared at the body.
It didn't matter how hard he tried to divert his gaze — his body didn't listen, forcing him to stay still and watch the blood pool out of the mangled figure.
His chest tightened painfully, head buzzing with static.
Even his hearing began to cut out, replaced by a loud ringing tone that blanketed out the screams still echoing in the town, leaving him with nothing but silence and fuzziness.
This was his job as an Astral — so why did it hurt so much?

Summary
Everything had gone wrong.
Cosmos wasn't even sure if he belonged in his family anymore.
The entire thing was just a toxic mess. The Astral's, dark stars, and relationship strains were all too much for Cosmos.
So like the coward he always was, Cosmos ran.
Except this time, he couldn't return.–
Moon had made everybody a small teleport device recently, just for safety measures.
Luckily, this came in hand for Cosmos. Gripping the device roughly, Cosmos allowed it to teleport him to a random dimension.
Colours surrounded his vision, he gasped, pulling himself out of the ballpit and looking around.
He heard a spark, pulling out the teleporter device.
It was broken.
Cosmos eyes widened.
He was stuck.–
OR
A universe where everything ended positively. Kill code, Bloodmoon, Ruin, Eclipse and Solar flare are all alive and redeemed. A universe where everything has settled down. And Cosmos gets stuck there and lowk gets adopted because I need more Cosmos content and my autistic ass came up with this.Series

Summary
Cosmos winced as the tree before him came undone, falling to the ground with a large crackle that rang out throughout the place — he only hoped the action hadn't disturbed any wild life.
He was frustrated, yes.
He never felt like this before.
Sure, Helpy used to be able to get his heart fluttering — but this? This was a whole other feeling threatening to consume him whole.
And like the idiot he was, Cosmos found himself giving in to the demand, rather than fighting back the void wrapping around his body and pulling him into territories he never thought he’d cross.
But that wasn't the worse of it.
At least with Helpy, there was a chance that they could love him back. A chance that they could have a happily ever after.
Gemini? Cosmos laughed at that thought — the idea of his feelings being mutual was like the concept of a pig flying in the air.

OR: Cosmos found himself in a situation he'd never thought he'd be in again. In love.From the book 'Cant Fix Your Family? Go To A Whole Other Dimension!' starring Cosmos and Gemini. You CAN Read this without having read the other book, but it may be confusing!
