Constance was a Badger Mother, who resided in Redwall during the Late Rose Wars. She constructed a giant yew crossbow in order to thwart Cluny the Scourge once and for all. She was most commonly thought as one of the strongest forces in Redwall, and was greatly feared.
When Matthias and others went to search for the young ones kidnapped by Slagar the Cruel, Constance helped in the resistance of Redwall against General Ironbeak. She then tutored Auma on being a Badger mother, who was Constance's successor.
