Following the events of the mission on Shu-Torun, General Carlist Rieekan tasked the Wookiee Chewbacca together with the protocol droid C-3PO with a mission: to attract a significant number of Imperial Star Destroyers to the planet K43 and subsequently obliterate it. Initially, the Rebel Alliance assumed the world was devoid of sentient life; however, Chewbacca and C-3PO discovered the Kakran people resided on K43, which forced a revision of their strategy.
