Swords of Sanghelios (Earth-2042)

"The Arbiter's forces eventually consolidated their strength under a single banner, the Swords of Sanghelios, an ancient title of honor expressing their nobility of their cause: the unification of the Sangheili people."

- C-3PO

The Swords of Sanghelios is an alliance of Sangheili keeps and the preeminent governing body on Sanghelios, as well as most Sangheili colonies through the galaxy. Originally an ancient Sangheili order, the Swords of Sanghelios was reinstated in the aftermath of the Great Schism by the latest Arbiter and the organization's leader, Thel 'Vadam. Individual members of the faction identify themselves with the title Sword of Sanghelios.

The Sangheili initially lacked organization after being cast out of the Covenant and the Confederacy of Independent Systems during the last months of the Clone Wars, leading various groups of Covenant separatists. Shipmaster Rtas 'Vadum led a significant number of their forces in the deciding battles of the war, although Thel 'Vadam would not formally establish the Swords until after the war's end. After the Covenant's defeat, the Sangheili-led groups would split off into various different factions, with the Arbiter and his followers coming to once again face opposition via the Galactic Empire. Secretly, the Swords of Sanghelios backed the Alliance to Restore the Republic, with 'Vadam and 'Vadum lending soldiers and equipment to the rebels.
