Obi-Wan and Anakin are on a mission to save a group of workers from the surveillance post of Typha-Dor located on TY44, a moon of Typha-Dor. The workers are holding valuable information about the invasion plans of Vanqor’s fleet. Vanqor is a world with few resources but they are strong militarily and have conquered all the planets in the Uziel system, except for Typha-Dor.
After rescuing the workers, Anakin and Obi-Wan are forced to land on Vanqor because their ship is under attack, crippled, and nearly out of fuel. Anakin and the TY44 crew are then captured and taken to a prison camp amidst the Tomo Craters. The camp is used as a place for insane galactic scientist Jenna Zan Arbor to experiment with her new drug, the Zone of Self-Containment, which is tested on Anakin.
Obi-Wan rescues Anakin, and (after fighting through a gundark nest) with the help of other Jedi, they begin their journey to Typha-Dor—only to learn the invasion has already begun. In the end, Typha-Dor’s fleet, with the help of the Jedi, is able to get Vanqor to surrender and undergo peace negotiations with Van-Ith, the ruler of Vanqor.
