"Oh, good."
She watches the door swing shut behind him, uneasily. "There's no such thing in a private conversation in an Elven fortress, but you mistake the source of my earlier discomfort. At least slightly. There's - so, Elves live forever, and Men do not. That means Elves will be better at anyhting they care to do than Men, and while they're very genial about it they're mostly either keeping us around as charity or as foot soldiers - because the death of their own is a tragedy. But Men? Die anyway. And now you have magic, which we need and which we're grateful for, and which you get better at with practice, meaning eventually all Elves will be more capable at it than all but the greatest of Men.
We take the rules about their conduct very seriously. It's not because I'm worried you'll lose your head for an Elf, though you wouldn't be the first, it's because they rule this continent and we are something between their charges and their meat shields and we have absolutely no capacity to retaliate should someone decide he wants to stretch his religious rules.
Be careful, all right?"
