Installation 07

Installation 07 is one of the seven Halo Rings. Very little is known about it but it appears to have a desert like land scape.

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 the Arbiter, Master Chief and the Prophet of Truth, once again displaying that Installation 07 was on standby mode, prepared to receive the signal to fire. However, the Master Chief deactivated the installation before it could be fired.
