This unnamed Elite Shipmaster is an Sangheili Shipmaster who fought in the Covenant-Human war and later became a Covenant Seperatist when the Great Schism broke out.
Battle of KholoEdit
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 Fleet of Righteous Vigilance 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, and destroyed three Orbital Defense Platforms, claiming he saw the best of Humanity's combat prowess at Reach.
The Great SchismEdit
When the Great Schism broke out, he confronted Conviction who attempted to kill the Shipmaster. He knocked out the Prophet and brought him forth in front of the crew, who were exposed to the images of the Elite Councilors assassinated by the Prophet's Brutes "puppets". When Conviction woke, he was later killed by the Shipmaster by crushing his neck.
Post Human-Covenant warEdit
From the day until at least 2559, he had been fighting the Brutes in the ongoing Great Schism. In that year, the Shipmaster returned to the human colony, Kholo, so that he could atone for his sins. The Shipmaster observed Humans in a small scuttle with a couple of Jackals, and came across a human who had been shot by a carbine. Believing the human would die from the 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 returned to the human and saw that the carbine round had passed through him and thought that the human could be saved, as he seen humans survive worse. This time he couldn't get the answers from the Prophets, but from a human, "Reclaimer" to the Forerunners.
