From Halopedia, the Halo wiki
Habitat La Paz was an area in the outer section of the Rubble. The area had several prisons, and was controlled by the Kig-Yar. The prisons were guarded by Unggoy equipped with plasma rifles. During the Battle of the Rubble in 2535, Thel 'Vadamee and his bridge crew were locked here. The Sangheili managed to escape to an airlock, by killing the Unggoy guards, where they hijacked a docked Kig-Yar shuttle.
Contrary to its name, which means Peace when translated, some of the more violent actions of the Battle of the Rubble happened here.
