Scoutmaster Hasark

Scoutmaster Hasark is an orc located north of the Dark Portal in Blasted Lands.

Attacking him would make Shadow Clones appear.

Speculation
Since he has a green skin, it is likely that he was a member of the True Horde and joined with the Iron Horde when they began their invasion. Or he could be a part of Okril'lon Hold and switched sides during the attack.
