Skirmish on Ossus The Skirmish on Ossus was a battle between Executor Sedriss QL ' s forces and the Jedi Knights Luke Skywalker , Kam Solusar , and their Ysanna allies . The skirmish saw the elimination of the Dark Side Adepts Sedriss and Goir along with the ancient Jedi Master Ood Bnar , and resulted in a mutual alliance between the Force - wielding Ysanna and the New Jedi Order . History . Prelude . Having been guided by a holocron to Ossus , Skywalker and Solusar traveled to the planet on Skywalker ' s new ship , " Jedi Explorer " . During the Old Republic era , Ossus had been a center of Jedi learning . Then in 3996 BBY , during the Sith War , Ossus was devastated when the Sith caused the planet ' s sun to go supernova . As a result , Ossus was reduced to a barren world and was forgotten for millennia . When Skywalker and Solusar arrived , they were attacked by an Imperial probe droid sent after them by Sedriss . However , the two Jedi defeated the automaton . They then traveled Ossus on their T - 77 Experimental Airspeeder . During their journey , they passed through ruins and canyons and they discovered that the Jedi had been strong on Ossus . They then encountered two Force - sensitive youths tied to a tree at the base of a canyon . Later Skywalker and Solusar would learn that the youths were Rayf Ysanna and Jem Ysanna and that they were members of the Ysanna , a tribe of warrior - shamans who were the descendants of survivors of the destruction of Ossus . Luke freed the two youths though they thought he was trying to kill them . They then encountered more Ysanna who rode on large beasts . The Ysanna — thinking that Skywalker and Solusar were enemies — attacked them with concussion - fired arrows . This was further enforced by the fact that the Ysanna spoke only Ysannan while the two Jedi spoke only Galactic Basic . These Ysanna used the Force to guide their arrows to the target . Skywalker and Solusar were forced to defend themselves with their lightsabers as a result . Impressed by the skill the two Jedi displayed , the Ysanna stopped fighting . The leader of the tribe , Chief Okko , then confronted them with his Force abilities . The other Ysanna , including Murra , joined in , but stopped when they saw that the two Jedi were friends . Though Skywalker did not bring C - 3PO , he was able to communicate with Chief Okko through the Force . Okko then realized that they were the long - lost Jedi Knights . Unfortunately , the Chief ' s cry of wonder was interrupted by the arrival of a long - range Imperial Hunter . The Skirmish . Upon landing , the vessel deployed a contingent of specially - trained Stormtroopers which were powered by the dark side of the Force . However , the Ysanna and the two Jedi fought them . During the confrontation , the Force - sensitive Ysanna were pitted against the best Stormtroopers in the Imperial arsenal . With the help of Skywalker and Solusar , the Stormtroopers were defeated . However , Sedriss and his cohort Vill Goir were still alive and they confronted the two Jedi Knights . However , Solusar defeated his former comrade Vill Goir for all time while Luke used the Force to hurl Sedriss to his knees . In desperation , Sedriss took the Ysanna girl Jem hostage . Unfortunately for him , he was standing behind the same tree the two Ysanna had been tied to and the tree was in reality the Neti Jedi Master Ood Bnar . Ood used his roots to grab Sedriss and then used the Force to disintegrate and destroy Sedriss . Unfortunately , Odd Bnar was killed in the process . On the positive side , the explosion revealed a vault which contained a wealth of ancient Jedi lightsabers . Also , Ood Bnar left a descendant behind . Skywalker , Solusar , Jem , and Rayf then took a lightsaber each from the treasure vault . They then discovered that the antiques were still operational . With this , Skywalker took Jem and Rayf Ysanna with him as students to start a new Jedi Order . Behind the scenes . The Skirmish on Ossus first appeared in the issue " " of the " Dark Empire " series of comics . The battle was conceived and written by authors Tom Veitch , illustrated and colored by colorist Cam Kennedy . Veitch used this as part of the rising action of the plot ; introducing the Neti Jedi Ood Bnar while killing off Vill Goir and Sedriss . The Skirmish on Ossus would eventually be featured in the " Dark Empire II " audio drama , which witnessed the skirmish take on a whole new personality through the voice acting of Jim Ward ( Sedriss and Kam Solusar ) , John Cygan ( Skywalker , Goir and Okko ) and Glynnis Talken ( Jem Ysanna ) . The audio drama of " Dark Empire " differs from the original comic " Dark Empire II " in regards to several aspects of the chronology of events in the battle . In the audio version , Sedriss is bested in duel with Skywalker , rather than being pushed back up against the tree - like Ood Bnar by the Force .
