"The door's been kicked and the information's been taken," Martel says, matter of fact, "all that's left now is to bring down the building."

He isn't, notably, explaining how he intends to do that; that's not accidental. They don't have time for Kirk to decide he's a madman and argue the reality of sorcery - god only knows the man's context, but even in Martel's own world the believers are few and far between outside of the knighthoods and Styricum - so he's not going to bother with it. He'll see it for himself soon enough.
