    What if there was an anomaly in the Underground? No, not Frisk. Not Chara either. Someone else entirely. How could a few measly children stand to this supposedly immortal foe and save the Underground from destruction? Is it even possible to do so? Only one way to tell... ~o0o~ Disclaimers before you start! •There is NO fanon ships. That means no Soriel, Papyton, etc. The only ships are Torgore (in the past) and Alphyne. •This is NOT an x reader. I dislike those types of stories. The reader will have no part in this, and they will not be shipped with anyone. •This exists outside of canon to an extreme. For example, Frisk is the second human and not the eighth. •There will be OCs, but only for a few humans and they still technically exist in normal Undertale. •There is a sequel. I'm planning on rewriting it after this one, as it is much more random and definitely needs it. Clanky, plot holes/retconning, etc. It's more of an OC thing, to explore them and their issues, than an Undertale thing, but it has its similarities. •There will be some explicitives. It won't be unnecessary or excessive, only when it fits the situation and character. I will not be using any slurs, as that's just plain disrespectful, even if some of them apply to me. Credits: Undertale, obviously, created by Toby Fox and Temmie Chang. "The Time Before" by ANinnyMouse42 is the backstory for Sans in this AU with some adjustments (mainly since that was very close to my original idea before I read it and I don't want people to think I copied their masterpiece or smth, if you haven't read it please do so, it's really good). Some things will be in reference to the other books in the trilogy or "From War to Science" by Emotistic-optimistic. If you haven't, read that too. It's really good (along with its sequel). The cover was made by me! Have a good day! (Also, the title is a placeholder, if anyone has any ideas that make more sense, please let me know.)

    It's been around half a year since your friend, Frisk, as you recall, managed to do something that broke the barrier and let the monsters live with humans. You weren't around in your hometown and neither Mt. Ebott to witness it, but you didn't care really. What was important, is that you returned from the trip that lasted what seemed a lifetime. So, you wanted to see what really happened. Was that a good idea? I'd say, debatable.. Boy, something told me I should've written this earlier! So, uhm, an short brief. YOU here are a MALE, 16 years old. CHARA and FRISK here are female. CHARA is 16 years old, too. FRISK is just a year younger than you. I am sorry to disappoint any readers that see the story the other way, but this is how I see it. Undertale belongs to Toby Fox And you uh.. Belong to you.
