Installation 06

Installation 06 is one of the seven Halo Rings. Very little is known about it and it has yet to be directly observed. Readouts of the ring on the Ark show it to be covered in blue with few distinguishing features, however, it cannot be said for certain if the ring is an icy world. Though it might be just the holo-image.

Activation
In 2552, during the Battle of Installation 05, a signal was sent to this Installation from Installation 05, putting it on standby mode. A readout from Installation 05's Control Room showed that Installation 06 was fully prepared to fire on demand.

Deactivation
A more comprehensive readout was later observed in the Installation 00, showing the inner ring to be covered in water or some form of blue rock, during the battle by the Arbiter, John-117 and the Prophet of Truth. Once again displaying that Installation 06 was on standby mode, being prepared to receive the signal to fire. However, John-117 deactivated the installation before it could be fired.

Trivia
