Warrchallra was a male Wookiee sculptor who worked with wroshyr wood. He hailed from Kachirho, a city located on the planet of Kashyyyk. This Wookiee participated in the Clone Wars, a conflict between the Galactic Republic and the Confederacy of Independent Systems. After the Galactic Empire occupied Kashyyyk following the Clone Wars, Warrchallra went into exile and joined the Wookiee underground as a freedom fighter. Before the Alliance to Restore the Republic was formed, Warrchallra conceived the idea for the "Liberty for All" propaganda poster. He shared this concept with Tavris Bahzel, a Clawdite illustrator (a shapeshifter who was then disguised as a Twi'lek), who then softened the violent imagery in the final piece. By 34 ABY, in that year, Warrchallra dedicated his artistic efforts to celebrating the people of the Wookiee culture.
