Valkor was a male Klingon priest who was a cleric that attended to one of the temples at the colony established on Korvat, which was later subjected to attack from the radical Red Path cult. During this assault, Valkor was one of the earliest victims, having been murdered at the hands of Alexander Rozhenko, who later remembered the savage execution after his interaction with a version of the deceased inside an alternate universe where he was a Starfleet officer.
