Chara has somehow stumbled upon the doodlesphere and finds the center of all the AUs. At first they're a little overwhelmed but then they quickly decide to use this to their advantage. Fast forward a few years. Frisk has found himself caught in a dare and ends up right where the story starts . . . Falling into the underground. Instead of monsters he has to battle against Sanses from other AUs in a new game called CardTale. Each card and character has a story to tell and a power to share. Frisk needs to help all these "monster cards" to regain their former lives and free them from the one who enslaved them in the first place.
Note : This doodle sphere isn't cannon and I hope @thecomyet doesn't mind that it isn't. - I'm currently asking creators if I can use their AUs in this so unless I have the ok i won't be continuing. That is of course if anyone is willing to let me borrow their AU for the world splice I’d appreciate it If you’d DM me because I have some plans for this thing.
