Murg "Oldie" Muckjaw is a level 70 quest giver located at the Dragonmaw Base Camp in the contested territory of Shadowmoon Valley. He is friendly to players who have completed  Blood Oath of the Netherwing. While he is a Fel Orc he has the model of a normal orc with red skin.
He starts the following quest at honored reputation with Netherwing:
-  Dragonmaw Race: The Ballad of Oldie McOld
It is odd that he rides a wyvern as they are not native to Draenor, said to be sentient in the Warcraft III manual, and the orcs had to convince them to join in Warcraft III.
