For Orual, Psyche has fallen victim to a delusion, and must be rescued from it. Psyche, as in the Greek legend, has been forbidden by her god to look on his face. Orual sets out to get her to break this command, and finally succeeds. You would fight your way through fire and spears to reach her. And I knew who wept, and what had been done to her, and who had done it.
Psyche ends up by becoming a goddess.
Orual fights against the consciousness of her guilt for most of her life, but in the end accepts it and is redeemed, with her sister's help. We also follow Orual's own life story, and it's very interesting. As queen, she rules with a compassion and wisdom practically unknown in ancient times, and not universal even now. For example, her father had used the silver mines as Stalin used the Gulag, to work his victims to death. She gave the slaves their freedom after they had dug out a certain quantity of ore, and the eventual result was that production soared.
