Ashpaw's mentor was Dustpelt while Fernpaw went to Darkstripe in hopes he would be distracted. Ashpaw's mentor had developed feelings for his sister Fernpaw. However Dustpelt trained Ashpaw well. His mother was killed by Tigerstar. Ashpaw and Fernpaw begged to be in Firestar's plan to lead the pack of dogs away from the camp. He allowed the two to run together.
Ashfur and Ferncloud became warriors. He received Birchpaw as his first apprentice. Brambleclaw was surprised that Firestar chose Ashfur because he wanted to get an apprentice. He soon fell in love with Squirrelflight but she wasn't interested.
Ashfur then hated Squirrelflight after she said she was in love with Brambleclaw instead. When he was still mentoring Birchpaw, he came allies with Hawkfrost, a RiverClan warrior. Hawkfrost told Ashfur to get his apprentice to trick Firestar into coming to a fox-trap.
He later got Lionpaw as his second apprentice. He became very harsh with Lionpaw, because his mother was Squirrelflight. When a fire started in ThunderClan, he trapped Hollyleaf, Squirrelflight, Lionblaze, and Jayfeather in it.
He told Squirrelflight that he was going to let her kits die for revenge of hurting him inside. Squirrelflight then reveals that they are not her kits. Hollyleaf was mad at him for hurting Squirrelflight, so she killed Ashfur.
