Hoarg was an old male dormouse, and the Gatekeeper of Redwall Abbey. He helped Mhera and Gundil in solving the riddle of Abbess Songbreeze, and also helped Cregga the Badgermum to hide the green pieces of the lilac-smelling cloth around the Abbey for Mhera to find. When some of the Juska attacked Redwall, he was one of the guards on patrol on the walltops. While on duty, Hoarg was once hit in the head with an arrow from Vallug Bowbeast, but he had donned a bucket as a helmet, so it absorbed most of the impact, letting him survive the incident with nothing more than a pierced ear. He later helped to capture Tagg, mistakenly thinking the otter was a weasel or stoat.
