Miridem

Miridem was a human controlled colony world. In 2544, the Covenant invaded the planet that eventually led to the Battle of Miridem. All that is known of this conflict is that SPARTAN-II Sheila was killed by the Sangheili Major Thel 'Lodamee and that Dr. Halsey was eventually taken hostage. The exact fate of Miridem is unknown, but given the events of the Human-Covenant War, it is likely that it was glassed by the Covenant.

Lance Corporal Morton, having previously lived on Eridanus II, lived on Miridem before moving to Minister.
