Dance of the Laughing Skull is the eleventh mission of the Human campaign in Warcraft II: Beyond the Dark Portal.
You have proven your strength in battle, but none can stand against the combined might of the Horde. We of the Laughing Skull clan, however, seek advantage from the turmoil of this war. With the aid of your strongest warriors, our clan can gain dominance over the northern clans of Draenor.
Do not show surprise, Human - only the strongest survive within the Horde.
You must secure the passes across the Blade's Edge Mountains and destroy the stronghold of the Thunderlord clan that dwell there. We will supply you with warriors and supplies culled from our villages. In return, we will give you the Book of Medivh, which we seized from Ner'zhul's stronghold before your armies could destroy it.
