I am curious as to how a character who can probably solve every world issue ever is going to fit seamlessly into the story. I could accept such a powerful entity as a mysterious background character, but as a PC I can't see it working out very well.

I'm going to reserve judgement for when I actually see it in action though. It's only in the RP that you find out if someone is going to nanny the universe or deal out harsh meta-game judgement.
