    Summary

    The streets were quiet in the Under-City, as it was still barely dawn. The slowly brightening sky casted wisps of oranges and pinks over the cobblestones, and stained the window panes of the sleepy town, a telltale sign of the quickly approaching sunrise. At first, this sight would appear quite serene, maybe even tranquil to the ignorant outsider, or the casual passerby. Frisk new better,however, then to trust the peaceful illusion presented by the empty streets of the Under- City as she stuck to the shadows of the back alley ways, refusing to so much as touch the light of the new dawn. This was Ebbot after all, and no amount of peaceful sunrises could bathe away the true grime of the Under- City that existed in the form of organized crime and corruption which clung to Ebbot like thick black tar. Though it might look pretty from a distance life was hard here, and making an honest living was a concept really only found in fairy tales.

    Summary

    Starring Spot and Voidster, before they ended up in The Sin Mansion.

    You're just trying to catch a break from your abusive boyfriend when you head up to Mt. Ebott, but things go from bad to worse when you fall into the Underground in the middle of a reset. Battered by kindness and cruelty, you do your best to survive as you get dragged between timelines. During your journey, you meet a doctor who struggles with morality and the fate of his people; the cruel, perverse skeleton that assists him; a kinder, gentler version of that skeleton; and a man so terrifying that he may destroy everyone you've come to care about. This story takes place in both Undertale and Underfell, as well as the void between worlds...

    Summary

    When Monsters rise from the Underground, humans promptly lose the ensuing war. The Monsters quickly assert their dominance and humans are reduced to "Pets." However, while not quite paradise, various global conflicts have ceased as well as local concerns, like different crimes. Being a Pet isn't all that bad either, as there are laws put in place to protect you and Monsters rather treat you as a assigned worker than an actual slave. You still have to go to school until you are 19 and after that, you go to one of the Educational Pet Centers, where you learn all the basic rules of being a Pet, as well as choose a Specialization.

    You've just graduated form the local EPC with a Specialization in Monster and Home Care, the most difficult, but impressive, Specialization a Pet can receive. As the only Pet in your class with this Specialization, this makes you an easy pick for your new Master, Sans. But, upon leaving, you notice the stares and whispers. Sans tells you that you are replacing a previous Pet that he and his brother had... "issues" with....

    And it seems as if not everyone has moved on....

    After the untimely death of your older sister and brother-in-law, you adopt your niece in hopes of giving her a semi-normal life.

It wasn’t until you met a friendly family of monsters that you realized, maybe you wouldn’t have to go through the struggles of practically being a single mom all on your own.

    Summary

    I cannot stop this sickness taking over/It takes control and drags me into nowhere
    I need your help, I can't fight this forever/I know you're watching; I can feel you out there

    Take me high and I'll sing/You make everything okay
    We are one and the same/You take all of the pain away
    Save me if I become my demons

    Human flesh was once the staple of the monster diet, but now that other food sources are available and science has determined there are better long-term benefits to a diet not saturated in human blood, monsters have begun rehabilitation. Now, human blood is a distant temptation, a secretly coveted drug that leads to ruin. Humans have integrated into monster society, have even found mates in monsters.

    Strings, an amnesiac skeleton monster, made the mistake of choosing the wrong one.

    Summary

    Consequences. Had you known there would be consequences, you wouldn't have done it. How were you supposed to know there would be consequences? You were just an oblivious god in a world full of oblivious gods, after all. You hadn't meant to ruin Undertale, ruin all the lives of your friends. Yet there you sat in front of your computer for countless hours, trying - and failing - to fix your mistake.

    It was a little game called OneShot that made you realize just what you were capable of, and now Niko might just be the only shot you have at saving Undertale. You've spent years planning and coding, leading up to this moment. And now, it's finally time.
