Clans of the Horde " NOTE : Following information taken word for word from Warcraft 2 : Tides of Darkness manual . " Blackrock Clan Chieftain : Orgrim Doomhammer Clan Colors : Red Background : Although years of war have reduced their numbers , the Blackrock clan remains the strongest within the Horde . Ruled for many years by Blackhand the Destroyer , the Blackrock clan rose quickly in power and was responsible for numberless victories against the Humans in the First War . Orgrim Doomhammer – known also as the Backstabber – assassinated the ruthless , but careless Blackhand , and named himself clan chieftain and War Chief of the Horde . The Blackrock clan continues to dictate the course of the war intimidating the lesser clans within the Horde into following Orgrim ’ s lead . The forces of the Blackrock clan are fanatically loyal to the Doomhammer and will serve him with their lives . Domain : Blackrock Spire , Azeroth Stormreaver Clan Chieftain : Gul ' dan the Warlock Clan Colors : Blue Background : The Stormreavers are a small but powerful clan whose origins are fixed in the history of the Horde since its coming to Azeroth . As the last of his kind , the Warlock Gul ’ dan maintains absolute control over this clan . Gul ’ dan , who secretly ruled the Horde through his unwitting puppet Blackhand , has found that the shrewd Doomhammer harbors no trust or fondness for him . This forced Gul ’ dan to found the Stormreavers in order to protect himself from any action Orgrim might take against him . With the support of his clan , Gul ’ dan intends to find the lost Tomb of the Daemonlord Sargeras . It is legend that this tomb contains unimaginable power – power which Gul ’ dan means to possess . Domain : Stormwind , Azeroth and Balor , Azeroth Twilight ' s Hammer Clan Chieftain : Cho ' gall the Ogre - Mage Clan Colors : Violet Background : Obsessed with the notion that the Horde is the harbinger of apocalyptic doom to all the lands that it ravages , the Twilight ’ s Hammer feels a sacrosanct gratification in the destruction of all that it encounters . Led by the cunning Ogre Mage Cho ’ gall , the Twilight ’ s Hammer has strong ties to Gul ’ dan and the Stormreaver clan . Its loyalty to the Horde is not as strong as its belief in its sacred mission of oblivion . Domain : Northshire , Azeroth The Black Tooth Grin Clan Chieftain : Rend and Maim , the sons of Blackhand Clan Colors : Black Background : The Black Tooth Grin clan was originally part of the Blackrock clan , but splintered off before the Horde ’ s passing into Azeroth . After their father was deposed from his position as War Chief by Orgrim Doomhammer , Rend and Maim decided to gain control over their own faction within the Horde without directly opposing the Doomhammer ’ s ascension to power . The Black Tooth Grin , noted for its custom of each member knocking out one of his own teeth to symbolize his loyalty to the clan , is charged with the protection and preservation of the dreaded Portal . The unity of The Black Tooth Grin may be sorely tested should the opportunity arise for Rend and Maim to reclaim their father ’ s station and avenge his death . Domain : The Black Morass , Azeroth Bleeding Hollow Clan Chieftain : Kilrogg Deadeye Clan Colors : Green Background : The Bleeding Hollow clan was one of the largest in the Horde before passing into Azeroth . Led by the aged Kilrogg , the Bleeding Hollow embodies the unrelenting savagery required for many long years of successful Orcish warfare . In accordance with their unequaled performance in battle , they have been given the honor of safeguarding the refinement operations in the occupied lands of Khaz Modan . Allegiant to the Blackrock clan , these veteran warriors place the needs of the Horde above all else .

With its legacy dating back into the time before the Warlocks , the Dragonmaw was quick to become one of Blackhand ’ s strongest supporters in Azeroth . After his demise , the Dragonmaw honored its fealty to Blackhand by pledging itself into the service of his sons and The Black Tooth Grin . Using ritualistic magiks dowered by the ancient Shaman , the Dragonmaw clan was responsible for the capture of the Dragon Queen Alexstraza and the Horde ’ s current subjugation of the Dragons of Azeroth . Domain : Grim Batol , Khaz Modan Burning Blade Chieftain : None Clan Colors : Orange Background : The Burning Blade is not a clan as much as it is an elemental force of nature . Chaotic and unpredictable , the Burning Blade is a brotherhood of demented Orcs whose only objective is to raze and plunder with no regard for their own safety . This leaderless swarm is held in check by the Ogre s – to be unleashed by the clans in times of urgent duress . The Burning Blade holds loyalty to no one and will attack any they perceive to be a threat – even their fellow Orcs . Domain : Nomadic
