Sabrina showed some interest to the assassin's words, she honestly haven't heard much about this brotherhood, other than rumors spread about the realm. Then again, she also mostly stayed in the keep with her family, safe, unknowing and quite un-caring about the outside world in the least. Why should she after all, they were mostly mortals in the outside world. If not, then trolls, giants, dragons, werewolves, and the un-dead roamed as-well, even machines made by the ancient Dwarves existed. 

She placed a hand on her hip, eyeing the female ahead of her. "For a pact full of secrets, you are rather open about yourself to a complete stranger, an un-dead one at that. Not to worry of course. No one would believe a vampire spreading tales of you much less a human doing the same thing. And i've no interest in doing so either. You are a...curiosity, that has peaked my interest however. But I believe I must get going, werewolf clans are growing more restless and the hunters are even more active than usual." She peered at the assassin, "Was a pleasure meeting you, of course. Do hope we meet again." She added, beginning to walk off instead of flying, she'd save it for later, more than likely.
