Nico Diath , a Human male , was born into a family that was known for producing a number of Jedi Masters . He was descended from the ancient Jedi Masters Sidrona and Dace Diath , who both fought in the Great Sith War . During the final decades of the Galactic Republic , he was trained in the ways of the Force by the Jedi Order and eventually achieved the rank of Jedi Master . During his time in the Order , Diath took his nephew Tae as his Padawan . Whenever Tae lost control of his telepathy , Diath made his nephew listen to his thoughts , which calmed the young man . Diath rarely visited the Jedi Temple on the galactic capital Coruscant ; instead , he roamed the Outer Rim Territories and liberated over one thousand slaves , which caused their Hutt slave owners to hate him . By the beginning of the Clone Wars , during which the Galactic Republic waged war with the Confederacy of Independent Systems , Diath was regarded as one of the legends of the Jedi Order . Four months into the Clone Wars , Diath traveled to the world of Queyta and met with Jedi Masters Jon Antilles , Fay , and Knol Ven ' nari in order to recover a sample of the antidote for the Separatists ' chemical weapon known as swamp gas . The Separatists had successfully tested the airborne gas against the Gungan colony on Ohma - D ' un , a moon of the planet Naboo . Diath was placed in charge of the team , and his group was soon joined by Jedi Knight Obi - Wan Kenobi . After he arrived , Diath and his fellow Jedi successfully infiltrated the mobile Separatist facility , which was located on a small island moving through one of the planet ' s lava streams . After accessing the facility , Diath and Ven ' nari noted the lack of battle droids guarding the base . As Ven ' nari prepared to attack the guards that were manning the base , Antilles noted that the guards were Skakoans — a species that breathed methane and was forced to wear pressurized armor — and that attacking them with a lightsaber would cause them to explode . Diath realized that the team would have to avoid the Skakoan sentries . Kenobi searched the facility ' s schematics and located the laboratory where the antidote was located . After reaching the laboratory , Diath and the Jedi confronted the Dark Jedi Asajj Ventress and the Gen ' Dai bounty hunter Durge , who were allied with the Confederacy . They informed Diath and his group that their spies had already informed them of the Jedi ' s presence in the facility . As Durge shot two of the Skakoans and caused them to explode , Ven ' nari used her pyrokinetic abilities with the Force to pull the fire toward her . After the fire subsided , Diath and the team found Ven ' nari with extensive burns . He used the Force to comfort Ven ' nari as she passed away . When the facility started to sink into the lava stream due to the explosion caused by Durge , the four surviving Jedi pursued Ventress , who had the antidote in her possession . However , both the Dark Jedi and the bounty hunter caused the facility ' s ceiling to begin to collapse . Some lava fell on Diath as he stood on a catwalk , burning the Jedi Master and causing him to fall into the lava stream . Before Diath was incinerated , he implored Antilles , Fay , and Kenobi to get out of the facility . Legacy . After Diath ' s death , Antilles and Fay were murdered by Durge and Ventress , respectively . Although only Kenobi survived , he was able to acquire the antidote and returned to the Jedi Temple on Coruscant . When Kenobi recuperated from his wounds , a holographic memorial service was held in honor of Diath and the other three Jedi Masters . During a Republic campaign on the planet Jabiim , Tae Diath came to believe that his uncle was stronger and more powerful than he and his fellow Padawans combined . Yet , due to Diath ' s death , Tae was losing control of his telepathy . Tae was killed during the conflict on Jabiim . Personality and traits . The Human male Nico Diath wore a set of brown Jedi robes and owned a lightsaber containing a blue crystal . He was regarded as one of the Jedi Order ' s nomads , rarely visiting the Jedi Temple on Coruscant . Diath , however , still fought for peace and freedom in the galaxy . During the mission to Queyta , Diath made it a point to stress the importance of their mission , despite the risk involved . As Knol Ven ' nari died , he took the time to ease her suffering . After her demise , he was determined to pursue the Dark Jedi Asajj Ventress . Before his death , he ordered Jon Antilles , Fay , and Obi - Wan Kenobi to flee from the facility . Powers and abilities . Diath inherited the Force - sensitivity of his family ' s bloodline , and eventually earned the rank of Jedi Master . When he trained his nephew Tae — who was a telepath — Diath encouraged Tae to listen to his thoughts whenever his nephew lost control of his telepathy . During the mission to Queyta , Diath demonstrated his ability with Force flight , using this to infiltrate the Separatist facility . Behind the scenes . Nico Diath was created by W .
