Bella of Brockhall

Bella of Brockhall was the daughter of Boar the Fighter, wife of Barkstripe, and mother of Sunflash the Mace. In Mossflower, she served as one of the leaders of the CORIM (Council of Resistance in Mossflower), a group of woodlanders against Tsarmina Greeneyes and her armies (although Bella was a peaceful beast). She and Barkstripe had lived peacefully in Mossflower until he was killed rebelling against Tsarmina's father, Verdauga Greeneyes. Sunflash ran away following that.

After Martin the Warrior defeated Tsarmina and restored peace to Mossflower, Bella helped lead the construction of Redwall Abbey. Seasons later, she helped raise Veil Sixclaw, but was also instrumental in banishing him after he attempted to commit murder. Not long after that, she was reunited with Sunflash, who stayed with her at Redwall until her death. Bella had the longest lifespan of any badger (and, since badgers are generally long-lived, presumably longer than any creature).
