Meridian

Meridian was a human colony planet.

History
The Office of Naval Intelligence's Section Three had facilities on the planet, to which several SPARTAN-II augmentation chemical precursors were sent without Dr. Catherine Halsey's consent, likely in order to be researched for Project CHRYSANTHEMUM. Meridian was home to many Chalybs Defense Solutions facilities, before they were abandoned sometime after the Fall of Reach. The planet was glassed sometime during the Human-Covenant War by the Covenant Navy.

The Office of Naval Intelligence apparently researched Forerunner artifacts on Meridian prior to its glassing.
