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 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.
