Does your Xion happen to have any previous game experience? We've got a respectable little KH cast going over at wethelost: Ienzo, Even, and Aeleus. It's a CRAU game, though, SoL-ish with some overarching plot elements and designed as sort of a healing experience for characters who have been run through the mill in various jamjars. I'd say it's slow-paced with a post every couple of days, but people will backtag into infinity.

It's set in a world being created by a new god. The characters brought into the world are helping to shape that god and, in turn, the world around them, as the god matures.
