Gods damn...return to post for the RPs I already have up, and I have idea for yet another AU...
Once Upon A Tale: Based off of OUAT and Undertale, but mainly the latter...Chara gains power by collecting Frisk souls from various multiverse, and using that power to cast a curse on the inhabitants of the underground. Everyone is transported to a contained, unchanging town outside of the barrier, where an aged up Chara is mayor. Despite this, even Chara is somewhat cursed in this, as all the monsters have become humans with their own changed roles and relationships in town...which they hate. But with power over all, they can massacre the town, or go complete pacifist, and the magic would reset it back to a point as if they had never done a thing. The only two who can stand to stop this are Frisk, who continues to age, despite the curse...and Sans, whose use of teleportation at the time had spared him from the full effects of the curse. You wouldn't have to know about much OUAT, but you do have to know Undertale.
