Second Onyx conflict

On October 29, 2558, a new conflict was sparked on the Forerunner shield world Onyx after the joint occupying forces of the United Nations Space Command (UNSC) and the Swords of Sanghelios came under attack by the Servants of the Abiding Truth, only for both sides to be caught by surprise by the appearance of a Guardian and its armiger complement as part of the wider Created takeover across known space. This marked the second major conflict in the Zeta Doradus system after the three-sided Onyx Conflict in the final months of the Human-Covenant War in late 2552.

Servants of Abiding Truth incursion
In October 2558, the Servants of Abiding Truth managed to gain access to Onyx. Pax forces attempted to find them immediately, but couldn't.

Created conflict
On October 28, 2558, The Reclamation began with the leader of the Created, Cortana, delivering an ultimatum across the galaxy. This message was heard on Onyx in the middle of the night.

Prelude
When the Guardian invaded Onyx, the students at the Pax Institute were brought back inside by Kasha 'Hilot and evacuated to the lunchroom. Due to the conflict, classes ended early, but the teachers decided not to send their students home right away due to the dangers outside. Some students protested and questioned Kasha on why they couldn't be sent home early, despite some of them living near the Institute. Kasha informed them that the school is the safest place for everyone. Some of the students believed they would be safer at home and suggested voting on it. However, Kasha told them her decision was final.
