Council Rock, a towering, unadorned black mesa, stood imposingly on Kashyyyk, encircled by platforms for observation; it served as the meeting place for the Wookiee government.
Prior to the Battle of Kashyyyk, Han Solo and Leia Organa Solo encountered Tarfang and Jae Juun, who sought to apprehend them. A struggle ensued between Leia and Tarfang over the Tyrossum jawbone, a symbol of conversational authority according to Wookiee tradition. The contest proved arduous and fierce for Leia, lacking her Force abilities, as Tarfang attempted to strangle her and strike her head against the stone. Ultimately, Leia managed to hurl Tarfang from the mesa just as Luke appeared. Tarfang then relinquished the jawbone, which bestowed speaking privileges at the Council, to Luke.
