Korm Bonegrind

Korm Bonegrind is a notably large orc that appears on a Horde gunship in the worgen starting zone quest Endgame (quest). He would appear to be a mechanic based on his title.

Speculation
Korm may or may not be a dire orc. It is possible that Korm Bonegrind is just an unusually large orc using a dire orc model for convenience. Nothing is said or shown of Korm's background, so it is unknown either way.
