Jedi Master Mavra Zane was assigned a group of Padawans around 21 BBY to train at the Kashyyyk Jedi outpost. They arrived there aboard a Consular-class cruiser.
After Master Zan arrived at the Jedi outpost with the younglings, an attack by a Confederacy of Independent Systems/Trandoshan alliance started. The Padawans took control of BARC speeders to assist the Wookiees. They fought against Trandoshan . They reached the nearby city and eventually fought off the first wave. Master Yoda departed to Coruscant to get reinforcements.
The second wave arrived sooner than expected. Zane ordered the Wookiees to get to their Raddaugh Gnasp fluttercraft, but they were destroyed. The younglings and Chewbacca took control of a Flash speeder and fought against the Separatist NR-N99 Persuader-class droid enforcer and OG-9 homing spider droids. Eventually they destroyed an Ubrikkian floating fortress. The younglings and Chewbacca were forced to escape to to the Star Runner.
They broke through the orbital fleet led by Nihilist, damaging several Munificent-class star frigates and HCT-2001 Dragonboat-class Reugeot 905 freighters.
The attack appears during the Jedi Destiny portion of the 2012 video game Kinect Star Wars.
