Trees Made Out Of Stars

Bill thinks making a deal with Pine Tree will be easy: Take over his body, find the journal, then destroy it and maybe cause some mayhem along the way. Of course, he's a powerful demon, so how could he think it would go incredibly wrong for him? In the end, Bill loses his powers and Dipper becomes a god. Stan Twin Theory. Pines Twins become gods. Mentions of crossovers/etc.
