Sister Atrata was a Redwall Abbey Infirmary Keeper, and the only sister during the time period of Abbot Daucus. She assisted in the recovery of Gorath the Flame. Atrata was later killed by the thieving watervole. It was mentioned that Sister Atrata dedicated her life to healing; she was a minor character, so not much is known about her. After her death, the Tabura stayed on at Redwall Abbey to perform healing duties.
