Attack on the Wookiee command center A command center built by members of the Wookiee species on the moon Alaris Prime was attacked by four predatory gundarks sometime between 39 BBY and 36 BBY . The command center was one of the early Wookiee bases on Alaris Prime during their colonization effort there , and prior to the attack , Jedi Master Qui - Gon Jinn had been instructing five Wookiee workers on techniques for gathering various resources . After a short period of time , the gundarks found and attacked the command center , but the workers retreated into the building and fired at the creatures with its turret , killing all of them . The Wookiee colonists later launched an attack on the gundarks ' nest in order to exterminate them . Prelude . Sometime between 59 BBY and 56 BBY , the Wookiee species from the planet Kashyyyk rediscovered Alaris Prime , a moon of the gas giant Alaris . These explorers , represented by the Wookiee Chieftain Attichitcuk , petitioned the Senate of the Galactic Republic to give their species colonization rights to Alaris Prime . After twenty years of debate , the Wookiees finally won the rights and headed for the moon sometime between 39 BBY and 36 BBY , with Attichitcuk being named leader of the colonists as a reward for his victory in the Senate . Attichitcuk ' s son , Chewbacca , was also selected as one of the colonists ' leaders , and Qui - Gon Jinn , a Master in the Jedi Order , was also sent to Alaris Prime by the Jedi Council to aid the Wookiees . Soon after they landed on the moon and established their first base , the Wookiees were attacked by gundarks , a non - sentient predatory species . The Wookiees defeated the creatures and began to expand their colony , with the next base established being a lone command center . Three Wookiee workers were stationed at the base , where Jinn taught them how to gather food for the colony by harvesting fruit from muja fruit bushes . Later , a fourth worker arrived at the base , whom Jinn instructed on how to catch fish from the nearby river . Another worker arrived at the command center after a sufficient amount of food had been gathered , and Jinn afterward had the Wookiees practice a drill in which they retreated into the command center to use its turret system to defend themselves in case of attack from the gundarks or any other enemy . Following the drill , the workers began gathering carbon from the nearby trees , which could be processed into duraplast and used for building . Chewbacca later arrived to assist at the base , and simultaneously four gundarks approached the command center . The attack . Using the Force , Jinn sensed the approaching gundarks and alerted the five workers . They immediately ceased gathering resources , retreated into the command center as they had practiced in the drill earlier , and fired at the gundarks with the turret . Chewbacca also used his bowcaster to attack the creatures , and all of them were killed without any serious damage done to the command center or the Wookiees . Aftermath . The workers exited the command center and returned to gathering resources for the colony . Chewbacca scouted the area around the base further and discovered supplies of nova crystals , a form of currency used in the galaxy , and ore , a mineral that could be processed into durasteel , which was useful for strengthening buildings . The workers gathered enough of these resources to sustain the base . Following the attack on the command center , Jinn decided it was time to take action against the gundarks , and he had the Wookiees train a small army to wipe out the creatures at their nest . When they launched the attack , the Wookiees encountered a squad of battle droids belonging to the Trade Federation , a corporation that had illegally started its own colonization on Alaris Prime . This led to several battles between the two groups , which ultimately saw the Trade Federation driven off the moon in the Battle for Alaris Prime Behind the scenes . The attack on the Wookiee command center was first mentioned in the for the 2001 PC video game " " , and it later appeared in the game itself and its 2002 expansion , " . " The attack is featured in the second level of the Wookiee tutorial campaign , " Gathering Resources , " in which the player uses the Wookiees and has to fight off the gundarks . The player may lose the level when the gundarks attack if the command center is destroyed .
