Kill Nak, Kuz, and Lok Orcbane and bring their skulls to Mangletooth at Camp Taurajo in the Barrens.
Three of my tribe came out of the Kraul to lead the raids against the Horde, <race>. <snort> They are ruthless and cunning, and if you defeat them, then your Crossroads and even most of the Barrens will learn peace... <snort> at least from the Razormane tribe. <snort>
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, <snort> a warrior. Kill them, <race>, like they have killed me.
