Aluco was an owl who lived in the tunnels beyond the Redwall Abbey cellars. He was once captured by the Painted Ones and held by them for five seasons. Their chief, Chigid, pulled out his pinion feathers so he could never fly again. While living in the tunnels, he ate Painted Ones. He also discovered one of the Doomwyte jewels and used its eerie green lights to pretend to be the adder Baliss, to frighten off the Painted Ones. He was found by Redwall residents who were searching for the Doomwyte jewels; Aluco then relocated to inside the Abbey.
