Ah, I suppose I might as well bring my monstrous swarms here, after all. What would you say of a tribalistically theocratic community, ruled by the highest echelons of an alien cult, which dwells in a maze of subterranean caverns and is adept at domesticating the various local more or less hideous creatures?

I'm working on a faction of Mad Max-style raiders which also have domesticated a kind of blind canine, which lives underground with them on secret caves. Hopefully our factions won't be too similar.
