(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😉)
