Hailstar was a loner who lived in the forest with her family, her mother Snow, her father Jett, and her sister Izzy. After a while Izzy decided to become a kittypet because prey had become scarce, and Jett died soon afterward from being hit by a monster. Snow never left Hail's side from then on. When she was sixteen moons she and her mother came across a cat named Ice who let them stay in his camp. Ice said that Hail was really a warrior and that she should stay on the moor where she belonged. Hail tried to get Snow to stay too but she had refused saying that she didn't belong there but Hail should stay. After that day Snow went to live with the twolegs, and Hail has only ever seen her once after that.
