Drull was a male rat captain in Ungatt Trunn's Blue Hordes. Drull was in charge of all the soldiers and guard patrols on the ground floor of Salamandastron, and when the attack on the mountain started, he reported it to Trunn. He and his group were sent to kill Jukka the Sling. During a final confrontation in the Salamandastron cellars, most of his group were killed by Jukka and Fleetscut, who in turn were also killed. Later, when Byle was sent to locate Drull, he was unable to find him.
