Two kings rule the kingdom of Avornis, trying to resist external and internal enemies. One of them, Lanius, is a hereditary monarch, but born of the king’s seventh wife, so his rights to the throne are questioned. The second king, a former galley captain who seized power peacefully, considers the welfare of the state his main concern. A dark shadow is approaching the kingdom - a deity excommunicated from heaven claims absolute power in Avornis. The Overthrown One can be defeated only with the help of the magical Scepter of Mercy. But he was kidnapped four centuries ago, and finding him is a dangerous and difficult task.
