Unidentified shipmaster (Righteous Vigilance)

This unnamed Sangheili Shipmaster was the main character in the story The Return, which took place six years after the death of the Prophet of Truth on the Ark. the Shipmaster returns to the human colony Kholo so that he can atone for his sins, which is the glassing of the colony during the Human-Covenant War. The Shipmaster served in the Fleet of Righteous Vigilance, under the command of the Prophet of Conviction, whom the Sangheili was eventually binded to after he successfully won the battle over Kholo.

The Shipmaster was there at the Battle of Reach, and destroyed 3 orbital MAC cannons. He claimed he saw the best of Humanity's combat prowess at Reach.

When the Great Schism broke out, he confronted the Prophet of Conviction, who attempted to kill the Sangheili. He knocked out the Prophet and brought him forth in front of the crew, who were exposed of images of the Sangheilian Councilors assassinated by the San'Shyuum's Jiralhanae "puppets". When Conviction woke, he was later killed by the same Shipmaster he was binded to during the war with humanity.

From that day until at least 2559, he has been fighting the Brutes in the ongoing Great Schism. The Shipmaster observed Humans in a small scuttle with a couple of Unggoy and Kig-yar, and came across a human who was shot by a carbine. Thinking that the human would die from his wound, he moved on. But he stumbled upon pictures of Humans observing Forerunner artifacts, one of which that resembled the Forerunner Oracle on High Charity. He went back for the human and saw that the carbine passed through him and thought that the human can be saved, as he has seen humans survive worse. This time he would not get answers from the treacherous Prophets, but from a Human, "reclaimer" to the Forerunners.
