The Siege of Aethia, formally known by the UNSC as Operation: OPEN GRAVE, was an engagement of the Insurrection that took place on the human Outer Colony of Meridian for three years between 2518 and 2521. After the Sundered Legion launched a campaign of antagonistic political ideologies throughout Meridian in 2495 that fueled several conflicts on the world, the United Nations Space Command intervened to prevent colonial destabilization.

After five years of near-constant conflict, the Sundered Legion was defeated by the UNSC at the Siege of Aethia. While rank and file members of the Sundered Legion were offered amnesty by the UNSC, the movement's leaders would stand trial in the courts of the Unified Earth Government.
