"Well, first I would like to find the authors of this book," he holds it up for her to look at, although that seems silly and pointless while he's doing it. Still, perhaps she can see all the way up there -- what does he know? "Just to, um, thank them for it -- I collect them, you see. Books and books of prophecy, and it's a bit of home I wasn't really expecting." Sure, the Priestess might have given it to him, but she didn't write it. And he's already thanked her.

As for what else -- "And ask them a bit about what they are, if they're open to that sort of thing and willing to answer. Back home, well. Those that are in attendance to God are rather special. I should like to know if there's any similarities here in this world."
