Kon Yel was a Kel Dor of the male gender, existing during the time of the Cold War that occurred between the Galactic Republic and the reconstituted Sith Empire. Working as a surveyor, Yel sought the assistance of someone allied with the Republic in order to prevent a catastrophic event at the destroyed Taris ChemWorks Factory located on the planet Taris.
During the period of the Cold War between the Galactic Republic and the Sith Empire, Kon Yel, a male Kel Dor, made his life. In the year 3643 BBY, he was employed by the Republic Resettlement, which was a part of the Taris Resettlement Initiative, fulfilling the role of a surveyor. He conducted an investigation of the remains of the Taris ChemWorks Factory situated in the vicinity of Lake Brell, where he discovered that the facility was on the verge of collapsing due to an impending meltdown.
Upon his return to Waypoint Station Draay, the nearest outpost belonging to the Republic, Yel made contact with his superiors and informed them that the impending meltdown would render the surrounding area completely uninhabitable. Given the high level of danger in the area, his superiors communicated to Yel that they would begin preparations for an evacuation. However, an individual allied with the Republic overheard the transmission and offered their help. Yel explained to this individual that the only means of preventing the meltdown involved performing a burnoff, which required the destruction of chemical stockpiles through the use of small, controlled fires. Because no teams were available to carry out the burnoff, the individual volunteered to undertake the task themselves. Despite the presence of rakghouls inhabiting the ruined facility, the individual successfully destroyed the chemicals and secured the area. Expressing his gratitude, Yel then contacted the project and shared the positive news with them.
The character of Kon Yel was originally created for Star Wars: The Old Republic, a massively multiplayer online role-playing game that was launched by BioWare on December 20 of 2011. He is featured in the Republic storyline on Taris at Waypoint Station Draay, where he assigns the "Burnoff" mission to players who choose the Republic faction.
