Hoarg was an old male dormouse Gatekeeper of Redwall Abbey. He helped Mhera and Gundil solving the riddle of Abbess Songbreeze. He was also one of the guards on patrol on the walltops. Hoarg was once hit in the head with an arrow from Vallug Bowbeast, but no harm was done, since he was wearing a bucket as a helmet. He helped to capture Tagg. Hoarg also helped Cregga the Badgermum to hide the green pieces of the lilac-smelling cloth around the Abbey.
