The preserved remains of an inmate were located inside a Sith oubliette, situated inside a treasure-filled chamber on the world of Dromund Fels. In 3643 BBY, a reconnaissance group came across the Sith oubliette.
Approximately during that time, a person affiliated with either the Galactic Republic or the re-established Sith Empire, which were engaged in an ongoing conflict, dispatched an associate to Dromund Fels to investigate the oubliette. While there, the associate found the inmate who was being detained within the oubliette.
The inmate was referenced in the 2011 electronic game Star Wars: The Old Republic, developed by BioWare, during the Crew Skill assignment titled "The Forgotten Prison." An initial iteration of the assignment was only available to players aligned with the Sith Empire and identified the reconnaissance group as an Imperial team. However, this detail, along with information about the mission's conclusion, was subsequently removed from the game.
