Star Wars Missions 20: Total Destruction, a book published by Scholastic in April of 1999, is the twentieth and concluding installment in the Star Wars Missions series for young readers, which also functions as a roleplaying game.
As a Rebel operative on a faraway planet situated within the Unknown Regions, you must confront the Empire's deployment of a device with the power to manipulate hyperspace travel. Should they achieve their goal, the Rebellion will face utter defeat, and the Empire's reign over the galaxy will become eternal. You represent the Rebellion's last chance. Your objective is to neutralize the Imperial device and foil the wicked schemes of Darth Vader.
May the Force guide you.
After discovering the Stellar Manx has been seized by Imperial forces, Han Solo commandeers a Marauder-class corvette belonging to the Corporate Sector Authority and gives chase. In the meantime, Chewbacca, Q-7N, and R2-D2 are concealed within the Millennium Falcon, located in the hold of the Manx.
Upon their arrival at Malagarr, Frap Radicon elucidates the concept of a gravity well projector to Tix and Mordak. Suspecting Radicon's sanity, the two Imperials decide to turn against their former allies, planning to steal the Falcon. They encounter Q-7N, who advises them to avoid provoking Chewbacca. The Wookiee, along with the newly converted Imperials, escape the planet and rendezvous with Solo's Marauder. Solo interrogates the Imperials and becomes convinced of their potential value.
Two Rebels pilot IRD-As down to the planet, successfully navigating through a field of Imperial space mines. Q-7N secretly boards Scout One's craft, which subsequently suffers a crash landing. Scout Two also crashes, but Scout One rescues them. Scout One then deactivates the gravity well projector before making their escape.
Q-7N reveals that Malagarr poses a significant threat to organic lifeforms and must be destroyed. With Q-7N being the only one capable of destroying the planet, Scout One and Scout Two quickly evacuate in the Manx, while the diminutive black droid obliterates Malagarr.
