Gerul was a young adult male barn owl. He was a good friend and traveling companion of Clecky and presumably lived with him in the Northlands. After meeting Martin II and his search party at the quarry, Gerul settled quite comfortably into the life at Redwall Abbey, defending the Redwallers against the gulls of Grall. Gerul had the peculiar and funny habit of frequently quoting his mother's advice and had a quaint northern accent. He and Clecky teased one another mercilessly. Not to be confused with Garul.
