The ship contained 94 holographic habitats, each tailored to make the stay of the prisoners as comfortable as possible. Habitats could be entered from the main body of the ship via hidden portals. These portals also linked one habitat to another. The habitats were individually named, including Argala, Bourget, and Zooabud.
The ship was shut down in late 2373 when the crew of the USS Voyager escaped and captured several high ranking Nyrians in the Argala habitat. They left the ship under the control of the other prisoners and disabled the translocater. (VOY: "Displaced")
