Installation 03

Halo Installation 03 was a Halo ring monitored by 049 Abject Testament. Everyone forgot that this was the ring that the Didact decided to hide his spare Composer, in case some bully bullied him out of his original one.

The ring itself had a desert climate but it still had oceans. This ring was the only other Halo apart from Installation 04 and 05 to be discovered by Humans before 2600, and was the only one that they found themselves after the Human-Covenant War.
