"My mistress rewards an empty vessel." The princess of the Qlippoth- who eats the souls of the damned but is never sated. She who conceals the light of Mercy and Truth.

To those who seek answers, it will provide in kind. The Keeper of Secrets bears no malice to its visitors, though the Night seems to take offense to its presence.
