Thrantin, or OM813, was the planet headquarters of Barosa Warren and the Galactic Outdoor School of Survival. It was located in the Ollonir Boundaries of the Colonies. Around 59 BBY, or before that moment, Old Republic scout Barosa Warren decided to retire and tried to create a survival academy. He obtained financial backing from some friends, enough to buy OM813 (renamed Thrantin). Then, during the four decades after it, Warren planetscaped all of Thrantin, aiming to create a training camp. While Warren admitted he should take students to different worlds to teach them, he also believed in having a "controlled environment" to ensure that none of his students could cheat. Warren thus created Zero-G areas, an Ammonia Ocean and the Heavy Grav Mountainous Zones.
