Lunk

Lunk is a pacifist ogre, involved in quests in the Searing Gorge requesting the player to do peaceful alternatives of what other quest givers asked.

Firelands Invasion
He later appears in the employ of the Guardians of Hyjal, working with them to push back the Firelands invaders. On a repeatable quest involving powerful elite monsters, and on another one involving gathering reagents for the injured Hamuul Runetotems medicine he fights alongside the player with a few other allies.

Trivia
This Ogre is most likely a reference to Oxhorn's Thunk, the good hearted Ogre who just wanted acceptance.
