AboutThe Swords of Sanghelios is a Sangheili faction that rose to power following the dissolution of the Covenant at the end of the Human-Covenant War in 2552. They are led by former Arbiter Thel 'Vadam, who allied with humanity during the later parts of the Battle for Earth and the Battle of Installation 00. The Swords' primary goal is to unite Sanghelios around a single leader and to cease fighting with humanity in order to focus on rebuilding Sangheili culture, livlihoods, and their homeworld.
When the Covenant fell at the end of the Human-Covenant War in 2552, billions of Sangheili were left leaderless and with a sense of betrayal after the Prophet of Truth tried to remove the Sangheili as leaders of the Covenant military in favor of the Jiralhanae. One Sangheili who thought he had the clout and support to fill the power vacuum was Thel ‘Vadam, who had served as fleetmaster during the war and at the tail end became the Arbiter, fighting alongside the UNSC against Truth and his remaining Covenant forces. In 2553, ‘Vadam formed an alliance based around Vadam Keep known as the Swords of Sanghelios who gained the support of the UNSC due to their stance of leaving humanity alone rather than resume the war. Though they also had the support of much of Sanghelios due to ‘Vadam’s notoriety and service record, they were also admonished by many others for their attempted peace with humanity, creating several competing factions who all vied for control over the Sangheili homeworld and the future of the species.
For over five years the Swords of Sanghelios fought off would-be usurpers during the Sangheili civil war, or known to the Sangheili as the Blooding Years. This included Avu Med ‘Telcam’s Servants of the Abiding Truth and Jul ‘Mdama’s Covenant. Though both proved a worthy adversary, the Swords of Sanghelios, with the assistance of the UNSC, won out, leaving them the sole leadership on Sanghelios by the end of 2558.
