One reason could be that Finn has grown tired of the limitations within fanfiction. In Adventure Time, Finn is a very action - oriented character.

So he sets off into the unknown, facing various challenges like dangerous creatures and harsh terrains. Along the way, he discovers things about himself that he never knew before, and this could lead to a new understanding of his place in Ooo.
