The camp's initial inmates were thirty-four Tal Shiar and Romulan Star Navy personnel left behind in Cardassian space after the joint Obsidian Order/Tal Shiar armada failed to destory the Founder's homeworld. Smugglers and other prisoners were added to the prisoner population shorthly thereafter.
They were shortly joined the next year by Klingons captured during their Empire's invasion of Cardassian space.
After the decimation of the Seventh Fleet in the Tyra System, over a three hundred Starfleet personnel from the destroyed vessels were brought to the camp, including Gedna Tachion, the highest ranking Starfleet Officer to be taken prisoner during the Dominion War.
At some point Br'enn began running genetic experiments on the inmates, namely Seff O'Rourke.
Like in many other Dominion POW Camps, prisoners were forced to fight the resident Jem'Hadar guards.
