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. 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.
