Nightmare found a young child a long time ago. When they fell into a coma it sent him over the edge. several hundred years later the child wakes up in a castle of darkness, surrounded by people, er... skeletons, that they don't know. Now they are being raised by murderers, cannibals, and world destroyers. Oh yeah! And their Uncle is the god of Death. Fun. WARNING (but not really): This story has been known to give people heart attacks and possible death from wholesome cuteness. I am not responsible for said medical emergencies or deaths. Read at your own risk. ~~~~~~ || Few things. 1) The first couple of chapters are going to basically just be Nightmare, but it's for plot reasons. 2) Dream is definitely going to be a little ooc. Don't like it, don't read. This is just for fun. 3) Like I said, this is just for fun. So, updates are when I feel like it. 4) I'mma try to keep the pronouns for (Y/N) gender neutral, but I may just drop that at some point. Depends mostly on what you guys prefer. 5) any art or videos added are not my own unless explicitly stated. Cool? Great. Let's get started.

Routine. The entirety of every living thing is dominated by it, human or monster. Everything HAS to be the same. It was in this that you were the exception. For you everything was new, every time line a detailed altered in order to satisfy your sadistic desire for a new ending, whether it be only a few details of dialogue altered or something else entirely. Monsters you once considered family you now butcher and slaughter without a second thought, after all, that's what the Reset is there for, right? And all at once it stops. Your small hold over the Underground is ripped away from you and you are thrown into a dying timeline, monsterkind's final attempt at self-preservation. You're alone, completely and utterly alone. Except one. And he has a bone to pick with you.

Your mother was always busy, working hard to keep a roof over your head. She worked day shifts so she was never able to take care of you, so she had to hire babysitters, beg a friend, or something along those lines. She wanted to bring you to a daycare, but being half wolf, you were usually classified as a "monster" by most humans. Human daycares had a strict policy about monsters, so you ended up going to a monster one instead. It was there where you finally felt at home. ---------- -Cover art made by myself- ~Chapters are 1000 words or longer~ I'm mainly doing this because these look really fun to make, and I am quite a big fan of Undertale AUs, though for the most part I try to hide that...I haven't seen many of these, and when there are good ones then it becomes a total OC insert after the first chapter or so, so I'm gonna try to avoid that. I know those types of stories can be a real letdown xD Let me know what you think!! It's appreciated. I'm also up for suggestions!!~ Please tell me where a spelling error (hehe) is so I can fix it. Thank you!! Also, please check out the original creators of all the AUs and the creator of PJ's Daycare. Love your works!
