Ura was a child of mixed spirits who was promised to Durc She was the daughter of Oda, a Neanderthal woman, and a Cro-Magnon man. The Clan regarded Ura's appearance as a deformity.
Oda told Ayla that a man of the Others had accidentally killed her daughter when he relieved his needs with her. Oda grieved for her lost daughter, and when she discovered that she was pregnant, she hoped that the child would be a daughter. Oda did not want to keep Ura when she saw that she was deformed, but Oda's mate forced her to keep the child as punishment for wishing for a girl.
When Oda saw Ayla's baby, Oda suggested to Ayla that Durc be mated to Ura, since they were both deformed and were unlikely to find normal mates. The leaders of both clans arranged for Ura to return with Brun's clan after the next Clan Gathering.
