Summary
What happens when a story creates its own plot? A script written out of control, or rather in its own control? The writer who held the pencil being absent, so the pencil starts moving on its own.
Ink wondered that, as the God of Creation. Everything in this multiverse was his. Except for a few things, but... that's not important!
What would happen if he lost hold of it, he thought.
Upon realizing Dream has been absent for 500 years, Ink realizes this what-if might be his reality, just by a tiny bit.
He thought he'd despise such a thing. So then, why is everything about this so enthralling, then? Enjoyable?
Why does he, the universe, love this out of control star?
Connected to the ask-fgod tumblr blog's lore.

Summary
A story from the perspective of a sans ship child. (Nightmares son ooo shocker no ones done THAT already) but with a twist! Kind of a slow burner as it starts as the main characters daily routine, but it will get interesting down the line. Expect fight scenes, blood, some horror elements and more! (no incest or any crap like that. I hope to add more chapters as I come up with more lore, but this is my first post in AO3 so I don't fully know how it works yet, progress may be slow) ENJOY!
(ps This is cringe but there NO ai here. I'd die before I used that to write, ai bros leave you are not welcome)

In the back of his mind he knew this was probably wrong, that he shouldn't be with Killer like this. Especially behind Nightmare's back… But the way Killer smiled at him, giggling and holding him close…

Summary
Trying to survive in an economy where monsters have emerged years ago, it even made your survival harder. To make it worse, A sudden snowstorm is coming. you couldn't stay in dark alleyways anymore due to violent people and monsters mostly creeping there, the streets were dangerous as well, it's too self explanatory.
Having no choice, you decided to break into abandoned houses- or you assume so. You've been doing this for months now, and it has been the worst thing to do ever, but surviving and safety comes first. The owners would kick you out every time, but atleast one day of sleeping comfortably was worth the trouble.
What happens when a human breaks inside an empty lodge, not knowing some skeletons are arriving home to rest their bones?

Summary
The Multiverse is vast and nigh infinite, possibilities, concepts, the very function of a world's reality only limited by sheer creativity.
Within this realm, Dreamtale exists as an enigma, plucked from another Multiverse entirely. The tragedy of it's Story forced to continue beyond it's Endings, for it forced the concept of Balance into the Multiverse's rules. Now open-ended, the only two Characters wanders throughout the Multiverse as one of it's Outcodes.
Dream broke out of stone to one colorful and curious Inkblot, so much to comprehend for someone so small. But alive nonetheless.
Nightmare woke up freshly dead.
Au: Get it? Cuzhe died lmao
