Unidentified shipmaster (Righteous Vigilance)

This unidentified Shipmaster was the Sangheili commander of the Fleet of Righteous Vigilance, who fought in the Human-Covenant War and later seceded from the hegemony along with his Sangheili brethren when the Great Schism broke out.

Battle of Kholo
In 2539, the Shipmaster served in the Fleet of Righteous Vigilance, under the command of the Prophet of Conviction. After discovering the location of the human colony Kholo by interrogating a human freighter pilot, the Shipmaster led his fleet to the planet and deployed forces on the surface. After the ground engagement, the Shipmaster hand-guided his ship's energy projector to carve the glyph representing "Faith" on the planet surface in a ritual glassing. After successfully carving the glyph, the fleet completed the glassing and the Shipmaster was bonded to the Prophet of Conviction.

The Shipmaster fought at the Fall of Reach, where he destroyed three Orbital Defense Platforms. He claimed that he saw the best of humanity's combat prowess at Reach.

The Great Schism
When the Great Schism began, he confronted the Prophet of Conviction, whose species, the San'Shyuum, had attempted to kill the Sangheili. The Prophet had heard of the start of the Schism and locked himself in his room, armed with his plasma pistol. On the way the Shipmaster was confronted by the prophets Honor Guards, with one raising his Energy Sword but the shipmaster only gently moved him aside and engaged the armed Prophet. The Shipmaster however, overpowered the Prophet after dodging his overcharged shot and brought him forward in front of the crew, who were exposed to images of the Sangheili Councilors assassinated by the San'Shyuum's Jiralhanae "puppets". He then executed Conviction and left with the crew to join the rest of the Sangheili.

Post-war
From that day until at least 2559, he had been fighting the Jiralhanae in the ongoing Great Schism. That year, the Shipmaster returned to Kholo so that he could atone for the sins he felt that he had committed. On Kholo, he discovered a human excavation operation among the ruins of a city. There, he observed humans in a firefight with a small group of Kig-Yar raiders, eventually fighting the Kig-Yar himself. Shortly thereafter he encountered two humans, one dead from multiple plasma shots in the legs and torso, and another who had been wounded. Thinking that the human would die from his wound, the Shipmaster moved on, but then stumbled upon pictures of humans observing Forerunner artifacts, including an "Oracle". He then returned to the wounded human; realizing that the carbine round had passed through the latter's body, the Shipmaster decided to try to save the human, calling in a medic from his ship, as well as a security squad, the ship's chief engineer, and a patrol of the surrounding area for Kig-Yar or human ships. It was his intention that once the human recovered, he would interrogate him in order to discover the reason for the excavations on the planet.
