She rules the city of Sigil from behind a veil of perfect silence. Feared by mortal and god alike, she flays her worshipers alive and casts her foes into inescapable labyrinths of despair. Only fools dare ask her to speak. And the Amnesian Hero has come with a question. When the god Poseidon tells a man with no memory how to recover his past, the unwitting warrior seeks out the Lady of Pain and finds himself banished to the Mazes. With the help of a beautiful - but dead - tiefling sorceress, a horned fiend with a dark disposition, and a deranged wind-priest who claims to be the center of the multiverse, he must discover the secret of the Lady's past - or confront a memory so horrifying it could tear him apart!
