Adventures in Hyperspace: The Last Blade Master was the planned fourth and final volume in the Star Wars: Adventures in Hyperspace Legends young-reader series, which follows the smugglers Han Solo and Chewbacca in the employ of Jabba the Hutt prior to the events of Star Wars: Episode IV A New Hope. The book was to be written by Ryder Windham, illustrated by Jeffery Carlisle, and published by Scholastic Inc.
Although Lucasfilm approved Windham's synopsis for The Last Blade Master, the book was ultimately canceled along with the series' third volume, The Big Switch. The approved synopsis is now available on author Joseph Bongiorno's fan site, The Star Wars Expanded Universe Timeline.
Han and Chewie are transporting an antique business droid, CZ-4—a gift from Boonda the Hutt to Jabba—when their hyperdrive malfunctions. They are forced to land the Falcon on a world inhabited by the Numm, humanoid aliens with primitive technology. The Numm are unable to provide the parts needed to repair the Falcon's hyperdrive. Rotten luck! The Numm become nervous at the sight of CZ-4, apparently because they are fearful of droids. While Han and Chewie consider their next move, CZ-4 goes missing. This is bad news because the droid is Boonda's gift to Jabba. If they ever hope to do business with the Hutts again, they must recover the droid.
At first, Han and Chewie suspect that the Numm are responsible for taking the droid, but they soon discover that this moon has another population: a group of war droids who have been terrorizing the Numm ever since their ship crashed centuries ago. The war droids once fought on behalf of the Krath, a long-forgotten secret society that once menaced the galaxy.
It is the war droids who have abducted CZ-4. The war droids' leader is known as the Blade Master (his arms house retractable metal swords), and he wants to cannibalize CZ-4 for parts. Chewbacca winds up competing against the Blade Master while Han rescues CZ-4 from disassembly. Chewie defeats the Blade Master. Han not only rescues CZ-4, but deactivates the other droids.
CZ-4 and Chewie figure out a way to quickly reprogram the remaining Krath droids to aid the Numm. The no-longer-threatened Numm are grateful to Han and Chewie, and lead them to the ruins of a crashed freighter (maybe the one that delivered the war droids to the planet). Chewie is able to salvage parts from the freighter's wreckage, and uses these parts to repair the Falcon. Taking CZ-4, Han and Chewie are now able to continue on to Tatooine, where they deliver the droid to Jabba. Jabba tells them he has another job lined up for them.
