There's something wrong with the timeline. You've lived in an underground crypt with cracked green walls for as long as you can remember. And that's entirely the problem, you can only remember so much. Even as tortures and experiments continue without end, you're plagued with nightmares and glimpses into a different life, a life outside the green walls that you've been trapped inside for your entire life. There's a demon in the lab. Somewhere, you're sure of it, the scientist whom you have learned to hate is keeping a secret, another human besides yourself locked away. You don't know why or how they're connected to you, only that their name is Kris and they might be the answer to everything. There's something wrong with the timeline. And the whole universe might be thrown into chaos and bloodshed before you can fix it.

And even if it means Sans is finally stepping up to fend for himself, even if he's finally once again filling the role of the protective older brother, Papyrus knows that something dark is coming...

FRANS This is a request and I have been really exited to start writing it! I really hope you like it! Echotale is not my AU! Neither is Jailtale! This is just my own little version of it. So please, do not get mad at me.

This story is about a version of Error who destroys not because of fate and not because he is crazy, oh no... here, Error destroyed because he wanted to die. all he wanted was for the pain to go away and he could finally sleep for the rest of eternity. but you can't get rid of an error without deleting the reason that it's there. ignoring it's warnings would only make it stronger. maybe even immortal. ---- Cover art by me! uwu k so this version of Error was born when I thought rrreeeeeaaallly hard about what the word 'error' actually meant. yes he is doing this all based on the idea that if he destroys the multiverse he can finally die. have fun~
