In an attempt to lure several Jedi into a trap on the planet Vandos , Confederate General Grievous kidnapped Anx Ambassador Quiyyen and confined him within a dug - out cave . After learning about the kidnapping , as well as a Confederate invasion fleet arriving in the Vandos system , the Jedi Council sent a rescue team led by Jedi Master T ' chooka D ' oon to Vandos . During the mission , D ' oon was accompanied by his Padawan , Flynn Kybo ; Jedi Master Jmmaar ; and a group of clone troopers . As they entered the cave , Kybo learned that they had fallen into a trap as they were confronted by Grievous and his super battle droid force . After Kybo rescued the ambassador , D ' oon ' s team prepared to retreat to their landed gunship outside the cave . To give his team more time to board the transport , D ' oon attempted to distract Grievous , though the cyborg general quickly slew the Jedi Master . The fallen Jedi Master ' s team , however , managed to escape Vandos with Quiyyen . Prelude . In 20 BBY , Confederate General Grievous , a known Jedi hunter during the Clone Wars , established a plan to lure several Jedi into a dug - out cave on the planet Vandos . In order to attract their attention , Grievous kidnapped Republic Ambassador Quiyyen and imprisoned him in the cave . While the Jedi Order was unaware of Grievous ' trap , they learned about the kidnapping , as well as information about a Confederate invasion fleet arriving in the Vandos system . In order to rescue the Anx ambassador , the Jedi dispatched Jedi Masters T ' chooka D ' oon and Jmmaar ; D ' oon ' s Padawan , Flynn Kybo ; and a group of clone troopers from the Grand Army of the Republic . The mission . Believing that there was indeed an approaching invasion fleet from the Confederate Navy , D ' oon ' s team needed to land on Vandos and rescue Ambassador Quiyyen before it arrived . Once the team landed their LAAT / i gunship near the cave , they left the vessel and — to their surprise — faced a group of super battle droids . Kybo realized that they had fallen into a trap and that Quiyyen was only the bait . Grievous , who was leading the droids , told his battle droid soldiers to not let the Jedi escape alive . During the onslaught , Grievous killed Jmmaar and many clone troopers . Kybo , however , found Quiyyen and brought him safely toward the Jedi group . With the Anx ambassador under their guard , the team raced toward their gunship . As they proceeded to board their transport , the super battle droids continued to fire their wrist blasters at the Jedi team . Seeing that his comrades needed more time to board the gunship , D ' oon turned his attention to the approaching Grievous and engaged the cyborg general in a lightsaber duel . Kybo watched as Grievous made short work of D ' oon with his lightsaber , an event that would stay fresh in Kybo ' s mind . With the group aboard the gunship , they departed Vandos and headed for the Republic capital planet Coruscant . Aftermath . After the mission , Kybo was present in the Jedi Temple and entered a meeting with the Jedi High Council . Because of the death of his master , as well as many other Jedi , Kybo wanted to seek revenge against Grievous . Instead of military action to target Grievous , Kybo asked Jedi Masters Yoda and Mace Windu if he could organize a small group of Jedi and target the cyborg general , an act that both Windu and Yoda frowned upon . Behind their backs , Kybo disobeyed their advice and sought out Jedi who were interested . That action would later drive Kybo to his death , as he engaged Grievous in a lightsaber duel on the moon Belsus , where he was killed when an explosion caught him by surprise . Behind the scenes .
