Betrayal from Within (1)

Objectives
Kill Nak, Kuz, and Lok Orcbane and bring their skulls to Mangletooth at Camp Taurajo in the Barrens.
 * Lok's Skull
 * Nak's Skull
 * Kuz's Skull

Description
Three of my tribe came out of the Kraul to lead the raids against the Horde,. They are ruthless and cunning, and if you defeat them, then your Crossroads and even most of the Barrens will learn peace... at least from the Razormane tribe.

Nak, Kuz, and Lok Orcbane are the ones you seek. They are far to the south of the Barrens. One is a spell caster, another a tracker, and their leader, the one called Orcbane, a warrior. Kill them,, like they have killed me.

Rewards
Upon completion of this quest you will gain:
 * 1500 XP (or at level 70)
 * +75 or +150 reputation with Orgrimmar

Progress
How goes your hunt, ?

Thork thinks he knows the truth about who leads the raids against his people, but he shall learn how wrong he is if you are successful.

My death is inescapable, but you have caused great pain to my enemies, so Mangletooth regrets nothing.

Completion
It is done then. Better it ends this way, says Mangletooth. They should have made sure I was dead when they turned their backs on me instead of leaving me here in this forsaken cage.

There is but one task left for you to finish,.
