He appears again in Urchin and the Raven War, when the swans from Swan Isle come to Mistmantle Island seeking help from Crispin against the ravens serving the Archraven. Unlike his father, Crown is not bossy and cares about other animals; he is reluctant to leave Mistmantle and carries Pitter and Scatter to Whitewings Island to obtain aid in the war against the ravens. Crown tells Crispin at the end of the fourth book that he wants to be a king like Crispin.
In Urchin and the Rage Tide , he becomes Lord Crown. When Corr the Voyager comes to Swan Isle, asking his help, Crown helps save Sepia. On the way to Ashfire Island to find Sepia, they get hit by the second surge of the rage tide, and Crown breaks his wing. After their boat is wrecked, they wash up on Ashfire, where they find Sepia. They take Sepia's undamaged boat, and return to Mistmantle. On Mistmantle, he is called "Mistmantle's Friend".
