It begins as the complaint of Orual as an old woman, who is bitter at the injustice of the gods. She has always been ugly, but after her mother dies and her father the King of Glome remarries, she gains a beautiful half-sister Istra, whom she loves as her own daughter, and who is known throughout the novel by the Greek version of her name, Psyche. Psyche is so beautiful that the people of Glome begin to offer sacrifices to her as to a goddess. The Priest of the goddess Ungit, a powerful figure in the kingdom, then informs the king that various plagues befalling the kingdom are a result of Ungit's jealousy, so Psyche is sent as a human sacrifice to the unseen "God of the Mountain" at the command of Ungit, the mountain-god's mother. Orual plans to rescue Psyche but falls ill and is unable to prevent anything.
