Lord of Outland Lord of Outland is chapter 6 of Curse of the Blood Elves . It was the final confrontation between Magtheridon ' s demonic legions and Illidan Stormrage ' s followers for the control of Outland . Prelude . After successfully closing Magtheridon ' s Shadow Portals and thereby cutting off the mighty Pit Lord ' s supply of reinforcements , Illidan , Kael ' thas Sunstrider and Lady Vashj marched upon the Black Temple . Magtheridon was outraged by this development , but typically for his arrogant kind he was not unduly worried - his citadel was extremely well protected by war machines and armies of Fel Orcs and Demons , led by the powerful Mistress of Torment and Master of Pain . As Illidan ' s forces made their approach he swore to crush the Demon Hunter and his retainers . Battle . Illidan split his forces , joining Kael in a frontal assault of the Temple whilst Vashj and her Naga insinuated themselves into the vast citadel ' s sewer and aqueduct system . Kael and Illidan immediately ran into problems in the form of Magtheridon ' s infernal war machines , which slaughtered many blood elves as they assaulted the Temple gates . Fortunately , Akama and his draenei arrived , pledging their services to Illidan . They were able to infiltrate the Temple and destroy the network crystals which powered the war machines , allowing Kael and Illidan ' s forces to overrun the gates . They claimed an armoury containing several Fel Orc Demolisher s , which they used to blast apart the Fel Orc encampments . Using the shadowy might of the Draenei again and again to sabotage Magtheridon ' s war machines , Illidan and Kael swept aside the Fel Orcs and Demons to battle and then kill the Master of Pain . Meanwhile , Vashj and her small group of Naga routed several flotillas sent to engage them and destroyed two subterranean bases , the Fel Orcs proving no match for the awesome might of Vashj ' s Royal Guard . With her remaining troops Vashj then fought the Mistress of Torment and her retinue , the Sea Witch eventually overcoming the vicious Succubus . With both of his lieutenants dead , the door to Magtheridon ' s chambers opened . Illidan , Kael , Akama and Vashj joined forces along with several captive Fel Orcs and Demons and assaulted the Pit Lord directly . After a terrible battle which killed many of the Illidan ' s forces , Magtheridon was finally defeated . Magtheridon was shocked by his defeat at the hands of these strangers . The beaten pit lord asked Illidan if he was an agent of the Burning Legion sent to test him . Illidan laughed and replied that he had come to replace Magtheridon . Aftermath . Illidan claimed himself Lord of Outland , and the remaining fel orc s and demons bowed down to their new master . However , the Betrayer ' s triumph was short - lived ; barely an hour after the battle , the skies above the Black Temple clouded and the spectral form of Kil ' jaeden appeared , demanding Illidan complete his task of destroying the Lich King . Cowed , Illidan once again gathered the Blood Elves and the Naga to him and marched upon Northrend . As with Maiev Shadowsong , Magtheridon was originally thought dead , but instead Illidan held him captive underneath the Hellfire Citadel , using his blood to create more fel orcs . < br > < br >
