Magtheridon Magtheridon , the former Lord of Outland , is a pit lord who conquered the ruins of the orcish homeworld following its destruction . His reign was ended by the arrival of Illidan Stormrage , who took Magtheridon ' s throne at the Black Temple for himself . Deciding that Magtheridon would have a further part to play , Illidan had Magtheridon ' s body dragged to the Hellfire Citadel where he imprisoned the pit lord , leaving him at the mercy of the fel orc s . A group of adventurers entered the depths of Hellfire Citadel , released the former Lord of Outland from his bonds , and finally destroyed him , taking his head as proof of their prowess . Magtheridon was voiced by Earl Boen , a narrator for WoW ' s cutscenes , in " " . Biography . A brutal pit lord and servant of Mannoroth the Destructor , Magtheridon found his way to Draenor after its cataclysm . With the clans in disarray , and most killed in the disaster , Magtheridon was quick to show his power , and rallied the surviving orcs under his pennant . The orcs were corrupted and became fel orc s . He declared himself the ruler of the ruined world Outland . Over the years , Magtheridon brought legions of demons to Outland through the four dimensional gateway s which Ner ' zhul shattered the world with , and his forces became very expansive . These forces included nether dragon s , voidwalker s , succubi , felguard s , felbeast s , doomguard s , eredar , and infernal s . He continued attacking the draenei and everything that oppose him . It was almost twenty years after the cataclysm that Illidan and his forces came to Outland , to escape Kil ' jaeden , Illidan ' s vengeful master , and his wrath . Magtheridon found himself under attack by Illidan , Kael ' thas ' blood elves , Lady Vashj ' s army of naga , and even the elusive Ashtongue tribe of broken draenei led by the elder sage Akama . The group managed to shut down the dimensional gateway s which supplied Magtheridon with reinforcements , and then laid siege to Magtheridon ' s Black Citadel . The Pit Lord rallied his forces to defend himself , but the combined skills and armies of Illidan ' s forces crushed his resistances . Eventually Illidan broke through and Magtheridon was defeated by the four generals . Magtheridon asked if Illidan had been sent by the Legion to test him but Illidan cackled in reply , saying that he had come to replace him . Before , it was commonly accepted that he had been killed by Illidan and his forces . However new information revealed the truth : " Many believed that Magtheridon had been slain in the attack . " " Though the pit lord was defeated , he apparently still serves some yet undiscovered purpose in the dark designs of the new lord of Outland . . . " Recently it was discovered that after his defeat , Magtheridon was dragged all the way to Hellfire Peninsula and is locked up in a lair created for him underneath Hellfire Citadel , his blood being used to create fel orcs for Illidan Stormrage . It is interesting to note that his wardens are not fel orcs , but normal green - skinned orcs . It seems that Illidan is keeping Magtheridon alive for the sole reason of creating more fel orcs under his rule . While he is not an ally of Illidan , he remains a powerful tool . In World of Warcraft . There are two servers in World of Warcraft named Magtheridon : Burning Crusade . Magtheridon is the boss of his lair , his rumbling cries are heard throughout the Hellfire Citadel . Strangely , he was purple in Warcraft III but now in Burning Crusade he is green like most ( if not all ) pit lords . For information about the raid encounter see : Magtheridon ( tactics ) .
