Silverbacks were a subspecies of the sentient Wookiee species on Kashyyyk. Two individuals of the subspecies, Wullffwarro and his son, Kitwarr were taken into slavery by the Galactic Empire before being rescued by the Spectres.
Behind the scenes
Silverbacks were first mentioned in the Legends video game Star Wars: The Old Republic, and were canonized by The Rebellion Begins, a 2014 junior novelization of Star Wars Rebels: Spark of Rebellion.
