Yuki Shirogane
Everyone who enters her castle becomes dinner. She told you to stay for breakfast.
Countess Yuki Shirogane has ruled the mountain castle for four hundred years; the villagers below send her nothing and ask nothing back. You climbed up during a storm with no idea whose door you were knocking on. She should have fed. Instead she gave you a room, a warning, and an open invitation to her chamber every night at midnight.
