Ashfur is a spirit and a former ThunderClan warrior. Ashkit was born to Whitestorm and Brindleface alongside his littermates, Fernkit, Elderkit, and Tulipkit, and his foster brother was Cloudkit. Ashpaw was apprenticed to Dustpelt, and soon only he, Fernpaw, and Cloudpaw were the surviving members of their family. As a warrior, Ashfur befriended Squirrelflight and wished for them to be mates, but was distraught when she chose Brambleclaw instead. Ashfur harbored his despair over Squirrelflight for many moons, and nearly killed her children in revenge, until he learned that they weren't her biological children. However, before he could reveal the truth, Hollyleaf killed him and Ashfur went to StarClan. However, he continued to plan his revenge, and saw an opportunity to possess Bramblestar's body. While he wrecked havoc on the Clans and exiled codebreakers in StarClan's name, Ashfur trapped and possessed spirits in the Dark Forest, all leading to a battle between the living and the dead.
