Long ago, two races ruled over Earth. Monsters, and Humans. One day, war broke out between the two races, a war that almost brought Monsters to an end. This AU is a concept change, and I hope you will enjoy reading it :) The story is complete, as I didn't think that making an Undertale-like story throughout the Underground would be interesting. You are free to continue this story as long as you contact me about it on my Discord account: Chara#5380. I will post informations about the AU on my Deviantart Account https://www.deviantart.com/the-para-dise/ like Stats, or some stuff about the background of the AU. Like magic, characters... all that kind of stuff.
