It seems like a cosmopolitan city like Khromarium might have a priest of any religion, even if it's just an itinerant monk or lone madman.  So why not roll to determine which one?

(d4, d6)  Random Divinity
1, 1        Apollo
1, 2        Artemis
1, 3        Aurorus
1, 4        Azathoth
1, 5        Boreas
1, 6        Helios
2, 1        Kraken
2, 2        Krimmr
2, 3        Kthulhu
2, 4        Lunaqqua
2, 5        Mordezzan
2, 6        Rel
3, 1        Thaumagorga
3, 2        Tlakk-Nakka
3, 3        Ullr
3, 4        Xathoqqua
3, 5        Yig
3, 6        Yikkorth
4, 1        Ymir
4, 2        Yoon'Deh
4, 3        Ythaqqa
4, 4        Yug
4, 5        Other (Jove, Nyarlathotep, the Green Man, Buddha, Xemu, etc.)
4, 6        Small local god or venerated ancestor

(If you don't want to roll, my vote would be for Xathoqqua or possibly Mordezzan, since a tomb is being raided.  But I would have the priest of Mordezzan make trouble somehow.)

I would go Xath in the initial setup--or at least think my players would. They would expect a cleric of Apollo to cramp their (depraved, greedy, terrifying) style but would be nervous a cleric of Azathoth, Mordezzan, or Kthulhu would beat them at their own game!
