Reva 'Kuro was a Sangheili and a former Shipmaster in the Covenant. During the Human-Covenant War he was a lowly commander of a CRS-class light cruiser, the Supplicant, and tasked ingloriously with monitoring Kig-Yar privateers employed by the Ministry of Tranquility, a task which he resented. Later in the war he served as part of a raider force, ambushing human commercial vessels in an attempt to sever supply chains and recover navigation data.
