(So you know how we got Glitchtale, UnderVerse and The Villian Sans Squad right?. Well what if I were to tell you guys that the three seperate series were the three horsemen of the undertale Fandom. That means if there were three then there's a forth horsemen, working behind the scenes that had started eons ago. Well ladies and gentlemen, we have got The Multiverses Soul on stage so cue in the introduction and let's see where this will take us. Also I don't own Undertale or any of these Aus, I only own the storyline, (Y/N), some of the enemies and five of her star pupils that I won't reveal for spoiler reasons). "(Y/N) we need you, please don't go!". "....But you don't need me anymore". (Y/N) is the goddess of the multiverse. She started everything off by creating her own universe using her soul but it wasn't always like that eons ago. There was a crazed enemy that wished nothing but DESPAIR and CHAOS from the multiverse she's created but (Y/N) had evaded the enemy's plans by saving five monsters that became her star pupils. However let's not focus on that, (Y/N) had awaken in her home to realize something is wrong with her multiverse eons later. What is wrong you shall ask?, well let's find out. (Also events take place after Glitchtale, Underverse and starting of the Villian Sans Squad so yeah the multiverse is in jeopardy when you think about it hehe, enjoy😉)

~On a very long hiatus~ When someone turns 18 they are given a tattoo, which matches their soulmate's. So it's a shocker when Y/n had two tattoos, both different. It's unknown to have more than one soulmate, especially when they don't even exist in your world. And then, you're kidnapped my a monster, and saved by an overly positive one. Then you realize... Your tattoos matched theirs. Nightmare and Dream have lived for hundreds of years. It was sad knowing that their soulmate could be born in a few more centuries. After all, most monsters live forever-humans don't. And in the midst of battle, tattoos suddenly show up on their arms. Now they just had to find you. Description of the soulmate au: Like mentioned, when someone turns 18 they get a tattoo. Monsters always have monster soulmates. But Y/n, Dream, and Nightmare are seriously different. Not only does Y/n have 2 soulmates, but they're both monsters. So their tattoos work differently-Dream and Nightmare only get their tattoos when their soulmate does. The tattoos someone gets represents them, and represents their soulmate. Y/n's is a butterfly, so on her soulmate's tattoo there will be a butterfly. That's it! UnderTale and DreamTale, along with any other AUs don't belong to me! This story is just a fun thing for me to do! Anyways, enjoy the story!
