Griley is an Alliance soldier who worked with Tarlo Mondan at an unknown point in the past. Griley, Tarlo, and eight others would came across an old dwarven town while in the Wetlands. However Horde had learned of the town as well and established their own camp. In order to eliminate the Horde forces present, Griley came up with an idea to grab anything of value and then blow it up when the orcs approached. The orcs being suspicious, sent in goblins to check things out and when they dug deep enough Griley blew the goblins up. With the orcs distracted Griley, Tarlo, and the others tossed their ropes over the west gate and sneaked out.
His current whereabouts are unknown.
