Yuh uh

A person ends up in the multiverse. They gain some sort of power, the powers to traverse universes and the ability to use offensive magic, unfortunately, these powers cannot be used to get back and they have a hard time using them. The star sanses want to protect this person and get them back while the bad sanses and Nightmare the leader wanted use the user their own plans to spread negativity. And Error wanted to delete them until he figured out they aren't a part of an Undertale AU.
