 * After nearly nine decades of war, a tentative truce is brokered between the Reformist San'Shyuum leader Breaking Shadow and the Sangheili leader Pelahsar the Strident. The Sangheili and San'Shyuum end the War of Beginnings, merging to form the Covenant. The High Council of Concordance ratifies the Writ of Union, clearly defining the roles of the San'Shyuum and the Sangheili. In addition to both species laying down their arms, they commission the construction of a shared mobile homeworld, the Holy City of High Charity. This event begins the First Age of Reconciliation.
