Installation 07



Installation 07 is one of the seven existing Halo Rings of the original twelve. Very little is known about its fate after the events of Halo: Primordium, where it's purpose and origin are detailed.

In 2552, during the Battle of Installation 05, a signal was sent to this Halo from Installation 05, putting it on standby mode. A readout from Installation 05's Control Room showed that Installation 07 was fully prepared to fire on demand.

A more comprehensive readout was later observed in the Ark during the Battle of the Ark by Thel 'Vadam, SPARTAN-117 and the Prophet of Truth, once again displaying that Installation 07 was on standby mode, waiting to receive the signal to fire. However, SPARTAN-117 deactivated the installation before it could be fired.

Brief History
Installation 07 was the Halo that was in possession of 05-032 Mendicant Bias when it was stolen from the Forerunners. Its diameter was originally 30,000km, but was nearly destroyed after a failsafe collision course orbit with a rocky planet, which reduced its diameter to the same as the other six rings that survived the Forerunner-Flood War. This was enacted by rogue Lifeworkers and presumably the Master Builder in order to stop 05-032 Mendicant Bias, in the event they failed or finished finding a cure for the Flood on the ring, in any genetic memories or observed immunities of humans. Thus, 05-032 Mendicant Bias enacted a plan to save the ring for the eventual use of destroying the Forerunners. Once 05-032 Mendicant Bias was eventually defeated in his plan, the Didact, out to save the life on the ring, ejected unessecary, unfinished, and damaged sections of the Halo to reduce its size and allow it to pass through a small portal, which lead to the Lesser Ark. This was necessary due to Installation 07's severely drained power supply At the command of the Didact, this Halo was sent through the portal after repairs were made one last time, holding the (presumably) Flood infected Forerunners processed by The Composer, the timelocked Graveminds (of which approximately ten had already developed), as well as any remaining species infected or otherwise; to remain untouched as a sacred tomb for approximately the next one hundred and one thousand years.

Trivia

 * This ring is often confused with Installation 01 because it is the first ring from the entrance to the Citadel. Although, it is in fact the furthest ring from the Ark's control terminal and is the last ring to have its hologram light up during the activation sequence
