He and Cinderkit are later apprenticed to Fireheart and Graystripe, now named Cinderpaw and Brackenpaw. Cinderpaw gets Fireheart, and Brackenpaw gets Graystripe. He is calmer during their apprentice ceremony. In one of their training sessions, his sister runs down to the frozen river. His mentor tries to catch a water vole, but the ice cracks. Brackenpaw stares at him in horror, until Silverstream comes to the rescue. This leads Graystripe to fall in love with her and Silverstream does the same thing. So Fireheart does most of his training after Cinderpaw cripples her leg permentaly and becomes Yellowfang's apprentice. When Brokenstar and his rogues Blackfoot, Russetfur, Jaggedtooth, Boulder, and Clawface attack, he is not mentioned, after the other rogues flee and Brokenstar is blinded and has lost 2 lives, Bluestar gives Brokenstar shelter in the camp and renames him Brokentail. Brackenpaw sees later that Tallstar, Nightstar, and their Clans are furious about Brokentail and they attack. Brackenpaw is training with Fireheart at that moment and he is the first to sent them. Fireheart warns ThunderClan and RiverClan fights on ThunderClans side. He recieves his name, Brackenfur.
MUCH, MUCH, MUCH, later, Bluestar gives him his first apprentice, Tawnypaw. Right before the battle with TigerClan, he and Bramblepaw notice that Tawnypaw is missing and tell Firestar. He whimpers thats is his fault. Firestar tells him how Goldenflower reacted and Bramblepaw says that she was FRANTIC.
He, much later, gets a another apprentice, Whitepaw, and then Hollypaw.
