Dyvo 'Lusovai was an Elite Zealot stationed aboard the small corvette,  the "Ardent Prayer"  which was on a refueling course with the Covenant Super Carrier, the "Long Night of Solace". He was one of the bridge commanders and attempted to defend the ship from the invading Spartans and Marines, but in the end, failed, and went down with the corvette and super carrier after Noble Five nuked it.
