In Kuur, the war between the gods and the demons, who were bound by the bonds of magical stones, has died down, but prophecies say that the chosen one will free them by receiving the sword Urthanriel - the Bane of the Gods. Kirin is a thief from the gang of Night Dancers. Having climbed into the house, he witnesses the ritual of summoning a demon. He doesn't yet know what he's gotten himself into, but the goddess of luck is guiding him. Losing part of your soul, being betrayed and sold, hating your father, singing for a dragon and learning magic - is it luck or ridicule? What are people close to him hiding from him? And why is the demon prince hunting him?
