Holding chamber

s are Covenant prison cells.

They are found within High Charity and in other Covenant ships, and are used for holding traitors, prisoners of war, and convicts. They have some sort of energy barrier on the front, which can be deactivated with a switch, in the case of the CCS-class Battlecruiser. However, on High Charity the prison cells had bars on the front, much like present day jail cells.

Trivia

 * These holding chambers are similar to those used in the buildings on Uprising near Installation 05's Control Room, and it is possible, if not probable, that the Covenant designed their holding chambers around the Forerunner chambers.
