We're still doing the religious revival thing to maximize the anti-shadow gods' visibility of and degrees of freedom in the Vault, right? The only church we still need to hear from is Cayden Cailean.
Now, on the one hand, it's been argued, and convincingly, that Cayden Cailean might not be one of the most anti-shadow gods. On the other hand, in fact it has not been convincingly argued that Cayden Cailean is anti-shadow; I have no idea what that guy is smoking but would have assumed that someone smoking such stuff would think Cayden Cailean a natural ally?
And at any rate, Asmodeus's hiring spree has radicalized a somewhat greater number of people than it's cowed. Don't get it twisted, Korvosa isn't Infernal Cheliax - an entire 12% of us are within an alignment step of Chaotic Good (a solid 2pp of whom score the top-right square on Pharasma's two-dimensional manifold). And Cayden Cailean, for all that he's a subversive element in ordinary times and a bad influence on the youth, has never been said to be a friend of Asmodeus.
So, "Megapope". None of us have managed to get through to Cayden Cailean yet, but it's known that the gods often wait on clericking their patsies until some kind of religious experience brings the potential minion closer in tune with the god than they usually are, probably because this is less effort on the lazy god's end of things - indeed, the entire polytheistic revival was premised on this idea - so we're still holding out hope. (The other clerics figured that you should preach last in case you turn out to think it'd be useful for causing appropriate religious experiences to create wine again.)
So... here we are. Entertain us.
