Ralg was a harvest mouse Dibbun of Redwall Abbey. His parents were the Gatekeepers, Hillyah and Oreal, and he had a twin sibling named Irgle. He and Irgle were quite the handful for their parents and often played in the pond. The twins were almost eaten by an angry gannet that had been wounded and residing in the Abbey attic, but they were saved by their parents and fellow Redwallers.
