Warrchallra was a Wookiee male wroshyr wood sculptor from the city of Kachirho on the planet Kashyyyk, who fought in the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems. During the occupation of Kashyyyk by the Galactic Empire following the war, Warrchallra lived in exile and became a freedom fighter as part of the Wookiee underground. Prior to the formation of the Alliance to Restore the Republic, Warrchallra provided the concept for the propaganda poster "Liberty for All" to the Clawdite illustrator Tavris Bahzel while the shapeshifter was disguised as a Twi'lek, who toned down the graphic violence it depicted. By the year 34 ABY, Warrchallra was focused on creating art that celebrated the Wookiee people.
