Brambleclaw and his brother Hawkfrost are being trained to gain pwoer by their evil father, Tigerstar. Brambleclaw is appointed deputy, chosen by StarClan, and soon after, Hawkfrost sets a trap to test Brambleclaw. He lures Firestar into a fox trap and tells Brambleclaw to kill him. Brambleclaw refuses, and Hawkfrost decides that Brambleclaw must be killed. However, Brambleclaw succeeds in killing Hawkfrost and saving Firestar, fulfilling Leafpool's prophecy that "before all is peaceful, blood will spill blood, and the lake will run red."
