What a strange place. He's not unused to the idea of very Church-like motifs being used for other, and even poly-theist faiths; the Temple is one for example, with their towering windows of stained glass. Back home, it's not something he sees often beyond the structures of the Abrahamic faiths. But the universe is wide, and he could be wrong even on Earth.

This is all to say that the idea that this is somehow appropriated does not spring to mind, despite recent experiences with idolatry and blasphemy. Curiosity sparks in him instead, and he finds himself looking around for information of any kind, be they books lying around or plaques beneath the windows. Or if none of those are evident, perhaps peering more closely at the altar and the two-headed figure will be more illuminating.
