Dulam was a male mouse who lived in the North Shores with Luke the Warrior's tribe. He had gone to gather berries while the rest of the tribe was attacked by Vilu Daskar, and thus escaped the ensuing massacre. He participated in the attack on the Greenhawk, and later sailed on the Sayna when it went to attack the Goreleech.
Dulam was taken prisoner on Volcano Island, and rescued by Luke and Vurg. Later, he was one of the four survivors when the Sayna was destroyed. After being picked up by the Goreleech, he participated in the ruse to fool Daskar into bringing the ship back to the homeland of the mice. He was on the aft of the Goreleech when it sank, and thus survived the sinking of the ship. Later, he went back to Redwall Abbey, which was still being constructed, and presumably lived out the rest of his life there happily. Dulam was also along with the other surviviors adopted as an uncle by the baby squirrel Chugger who they all liked as he made food for them on the return journey to Redwall Abbey.
Not to be confused with Toolam.
