Ulon Glost, who held the title of Chief, was a male Mustafarian residing on the volcanic world of Mustafar during the era of the Galactic Civil War. He served as a crew chief overseeing mining operations for Mensix Corp at their Mensix Mining Facility.
In the year 1 ABY, a dangerous [tulrus](/article/tulrus/legends] that consumed humans launched attacks on multiple mining teams under Glost's supervision, resulting in injuries to several miners and the deaths of eight individuals who were conducting survey missions in the vicinity of the Tulrus Nesting Grounds. The mining crews, gripped by fear of the creature, refused to venture out until the threat was neutralized. Consequently, the Mensix Mining Company made the decision to contract a hunter to ensure the safety and security of its workforce.
Glost was pleased to encounter a skilled hunter at the Mensix Mining Facility who agreed to locate and eliminate the man-eating tulrus. Given the miners' inability to identify the specific tulrus responsible for the attacks, the hunter was compelled to kill several of the creatures to analyze the contents of their stomachs. However, while the hunter was still occupied with examining a deceased tulrus, the perilous beast struck again at a mining camp. By the time the hunter reached the camp, the majority of the miners were either dead or in the process of dying. The beast, a massive and enraged tulrus known as Foehorn, remained in the vicinity of the camp. The hunter engaged Foehorn in combat and, following a difficult battle, successfully killed the creature.
Upon the hunter's return, Glost presented them with a tulrus spine that had been mounted as a reward.
Chief Ulon Glost functioned as a Non-Player Character (NPC) within Trials of Obi-Wan, which represented the third expansion pack for Star Wars Galaxies, a MMORPG developed by Sony Online Entertainment, before the game's servers were shut down on December 15, 2011. Players could locate him at the Mensix Mining Facility situated on Mustafar, where he provided the quest titled The Man-eater. This questline tasked players with eliminating several tulruses, including the specific tulrus known as Foehorn.
