"It's no better or worse here than anywhere else, as long as you aren't on the run."

She'll still watch out for vampires. Because diablerie can't be hidden, she's been told, at least not in the months or years after. It was all a bit vague, which she didn't worry about then but which makes this harder now. But it's a risk not worth taking.

And besides, she still can't figure out who even rules this city and where they are.
