|Chronological and political information|
Sometime before 4,000 BBY, Bacca was exploring in the Shadowlands when a ship crashed, killing all passengers on board. This was the Wookiee race's first encounter with advanced technology and the first evidence they had that life existed beyond their own planet. Bacca crafted a ceremonial blade from the ship's hull and rose to become Kashyyyk's greatest chieftain.
The blade was passed down from chieftain to chieftain as a symbol of leadership. At some point, Bacca's descendant Chieftain Rothrrrawr fought a terentatek, managing to wound the beast, but breaking off the blade inside the creature. He fled only with the hilt of the blade, which continued to be passed down through the generations. In 3,956 BBY, the blade was recovered by Revan and put back together with its handle.
His name was also carried with many Wookiees after him, such as Chewbacca, Kybacca, Weebacca and Lowbacca. "Bacca", as added to Chewbacca's name, denoted him as a descendant of Bacca's noble lineage.
The word 'bacca' translated into as "Ally" or "Friend" in Shyriiwook.
