[@wikkit] I'll admit the first idea intrigues me, and would be an interesting piece in the overall puzzle. However, it isn't unheard of for freak accidents to thrust otherwise totally unprepared individuals into the role of being their world's New God. Often these people end up dead and more powerful Gods take over their territory.

The thing with being an actual, functional God (as the title is understood in Heaven) is that it basically means you have a job. There's a function you serve in Heaven's multiversal society, and what that function is typically describes what you are the "god" of. Many Law Gods, judges and other judicators, exist within Heaven. In fact there are multiple, competing "pantheons" which pay homage to different "supreme" deities.

[@Zyx] I'd pretty much handle it on a case by case basis. At the level our characters should generally be at, power is more of an abstraction.
