Laughing Skull clan The Laughing Skull clan is a very deceptive and treacherous clan of orc s that is distrusted by most of the other clans for their kinship of thievery and assassination . Although their loyalty is questionable , their skill and audacity are unequaled . Their treacherous leader , Mogor the Ogre , and most of his clan remained in Draenor during both of the crossings . Beyond the Dark Portal . Before the reopening of the Dark Portal . When the elder shaman Ner ' zhul first began developing his plan to open more Dark Portal s , he required the knowledge of a specific order of death knights who knew how to rebuild the original Dark Portal . Mogor , the renegade ogre - mage of the Laughing Skull clan , had taken control of this group of death knights and was using them for some dark purpose of his own . Ner ' zhul ordered a small force of orc s , ogre s , and a death knights from the Shadowmoon clan to attack the Laughing Skulls and subjugate Mogor ' s death knight , although the death knights were using the color of the Shattered Hand clan , they were secretly manipulated by Mogor . Ner ' zhul forces rescued Grom Hellscream , who had been held prisoner by the Laughing Skull clan , and with his help the attack was carried out successfully and Ner ' zhul gained the knowledge required to open to portal back to Azeroth and begin the next stage of his plan . Second crossing . After the reopening of the Dark Portal a group of Laughing Skull warriors crossed it , they established near the citadel of Nethergarde , there they fought against Danath Trollbane and his army , in this battle all the Laughing Skull warriors on Azeroth were killed by the Alliance of Lordaeron . The Alliance invasion of Draenor . When the human armies invaded Draenor , the Laughing Skull clan fended off the Alliance Expedition with a daemon and skeletal warrior s but were defeated . Then the Alliance Expedition invaded the shipyards of Zeth ' kur , with this the clans were driven to new heights of fury , one of the nearby island of Zeth ' kur had a Laughing Skull encampment and was destroyed by the Alliance . After defeating Deathwing the Alliance attacked the Skeletal Coast , one of the islands near the coast had another Laughing Skull encampment , the clan ' s warriors were defeated , however they delayed the Alliance and before they could attack the Fortress Shadowmoon , the Laughing Skull stole the Book of Medivh from Ner ' zhul . The betrayal of the Laughing Skulls . When the Alliance Expedition went in search of the Book of Medivh , they sided with Mogor and his clan . In exchange for the dominance over the northern clans of Draenor and securing the passes across the Blade ' s Edge Mountains , he promised to deliver to the human s the Book of Medivh . The Alliance forces had now formed a truce with the Laughing Skulls . Khadgar , Alleria , Turalyon , and their strongest warriors reinforced Mogor and the Laughing Skull clan and stopped the Bonechewer clan , then attacked a stronghold of the Thunderlord clan ( possibly Thunderlord Village ) and destroyed it , gaining the control of the region . Mogor was uncharacteristically true to his word , and managed to escape the wrath of the shaman Ner ' zhul , when the world of Draenor tore appart , Mogor and his clan went with it . After helping the Alliance obtain the Book of Medivh , Mogor and his clan apparently remained with their newly won lands as the Alliance continued on to the Dark Portal . While the Shadowmoon clan fled through one of the newly created portals there is no sign that Mogor and the Laughing Skull clan did the same . Current state . Following the destruction of Draenor , a brutal pit lord named Magtheridon rallied the surviving orcs under his rule . After Illidan captured Black Temple and imprisoned Magtheridon , the forces of Outland ( as named by Magtheridon ) were once again united under one banner . The present - day Laughing Skull clan is now based in the northernmost reaches of Nagrand , possibly still under the sway of the aforementioned pit lord . Laughing Skull assassins can also be found throughout the Blood Furnace of Hellfire Citadel , striking from the shadows before adventurers knew they were there .
