Fortunately for Weller , the injury was non - fatal , and he was quickly evacuated to a nearby medcenter . Biography . A Force - sensitive Human male , Derrin Weller was inducted into the Jedi Order and had risen to the rank of Jedi Knight by the year 3643 BBY . Weller oversaw the Order ' s training grounds in the Tythonian Gnarls , a region on the planet Tython to the north of the Jedi Temple , during the Cold War between the Galactic Republic and the Sith Empire . He maintained an office at the nearby Masters ' Retreat , where he greeted newly – arrived apprentice s and gave them information on the Order ' s homeworld before sending them to the Temple to meet with the Jedi High Council . In this capacity , Weller greeted a young initiate who had been trained under several Jedi Masters and had a reputation as an expert duelist despite the learner ' s youth , but his plans to send the student on a speeder to the Temple were interrupted by an emergency signal that reached his office . The message was from the Bith Padawan Unaw Aharo , who frantically explained that the Flesh Raider s — Tython ' s violent native species — were attacking the training grounds and were using blasters . Disturbed by the possibility that the Flesh Raiders might be using advanced weaponry , Weller dispatched every available Jedi at the Retreat down to the training grounds , including the young apprentice who had just arrived , while he contacted the Jedi Council . After he reported the attack on the Gnarls Outpost to Jedi Master Orgus Din and the rest of the Council , Weller himself joined the battle against the Flesh Raiders , but he was shot in the leg while rescuing several Padawans . While preparing to be evacuated to a nearby medcenter , Weller contacted the apprentice from earlier and ordered the young Jedi to follow up on Aharo ' s transmission — locate the cave entrance through which the Flesh Raiders were entering the Gnarls and to stop them at the source . After reassuring the student that Master Din was also heading to the cave as reinforcements , Weller terminated the transmission and received treatment for his wound . Following Weller ' s orders , the apprentice discovered that the Flesh Raiders were being led by a Dark Jedi named Callef , and the young Jedi defeated Callef in battle before Din arrived to seal the tunnel . Personality and traits . Derrin Weller was fair - skinned with brown hair and eyes , and during his time on Tython the man wore dark robes like many other Jedi on the world . Weller was calm and reserved in bearing , and he was more than willing to share his knowledge with the young Jedi whom he greeted upon their arrival to Tython . He maintained the same cool head when tense situations arrived , and he understood the value of knowing one ' s enemy before engaging in battle . Once Weller was wounded in combat , he allowed himself to be evacuated to a medcenter but ensured that the battle would go in the Order ' s favor despite his absence by sending Master Din and the young apprentice to seal the cave tunnel . Powers and abilities . A Jedi Knight charged with the protection of the training grounds in the Gnarls , the Force - sensitive Weller was a competent lightsaber combatant and proficient in the use of the Force . He was able to single - handedly rescue several Padawans from many attacking Flesh Raiders , though he received a leg wound in the process . Behind the scenes . Derrin Weller first appears in " Attack of the Flesh Raiders , " the opening mission for the Jedi Knight class in the 2011 video game " " . He welcomes new players to Tython and sends them into the Gnarls to fight the Flesh Raiders , and later contacts players to send them to find the cave that the Flesh Raiders are using to enter the Gnarls . Despite having an office in the Masters ' Retreat , Weller is referred to as " Knight Weller " in all conversations . Players who choose dark side options in the mission " Dark Temptations , " in which the player can choose whether to spare , kill , or depose the Twi ' lek Ranna Tao ' Ven as Matriarch of Kalikori village after she participates in a failed plot to kill the player , will receive a message from Weller regarding the situation in Kalikori , as he has been appointed as warden there . Players who chose to kill Tao ' Ven are informed that the new Matriarch is far more cooperative with the Jedi than Tao ' Ven — who was reported as being killed by Flesh Raiders — while players who chose to depose her learn that Tao ' Ven ' s successor accepts Jedi law and submits to the Order ' s authority . Players who chose the light side option of sparing her receive messages from Tao ' Ven herself regarding her current situation , and this article assumes that the player chooses only the moral light side options as a Republic Jedi Knight character . Weller is also mentioned in the mission " Early Lessons " when Jedi Knight players speak with Master Relnex at the Gnarls Outpost , while the conversation for Jedi Consular players mentions Yuon Par instead .
