what's the adventure time au u drew for?
Ah, that was for the Ice King Finn AU that Kuruk and I came up with, more than a year ago now! It’s basically a continuation of the alternate timeline from “Finn the Human” and “Jake the Dog,” only with less “being re-rewritten out of existence” and more “Finn becomes the Ice King and interacts with canon characters from there.” Alternate universes created by diverging timelines and all that.
