Wirga was an old female searat in Raga Bol's crew. She wasn't a good fighter, but she was a seer and a healer, and she fixed the hook on Raga Bol's paw. She had three sons, who used blowpipes with poison darts. They were sent with Jibsnout to ambush Lonna Bowstripe, but Lonna killed two of them and Figalok killed the other. Wirga didn't seem to ever miss them. However, this is probably because Raga Bol hid news of their deaths from his crew and slew the messenger. She was killed by Toran Widegirth near Redwall Abbey when she was trying to ambush Lonna.
