Liberation of Kessel

Shortly after the Imperial Remant was removed from Kashyyyk in the Liberation of Kashyyyk and Avatar Orbital Platform was destroyed, the Wookiees heard news that the Imperials shut down the air processing factories on Kessel.

Led by Han Solo, Chewbacca, Lando Calrissian, and Luke Skywalker, the Wookiees reactivated the processors and liberated the prisoners.
