That's what Zilla and I agreed to, though that question can't be fully anwered without Zilla's input, of course, so I'll link him over.

I don't think we have actually put thought into how they converted, though I would assume Spodism was brought to Mirus directly by the CoS at the time of the Great Expansion. At the very least, Zilla and I agree that the races that now form the Theocracy were once direct subjects to the Clericarch. The Second stagantion would hit these territories hard, causing each of the three Mirisian satrapies to enter isolation on it's own, becoming de facto independent (though de jure they would still count as part of the CoS until the very end). This would also result in the genetic drift between all of them. As for the conversion before/after becoming spacefaring, it would probably depend on the race.

@Zilla: Input?
