Undercity The Undercity is the capital city of the Forsaken undead of the Horde . It is located in Tirisfal Glades , at the northern edge of the Eastern Kingdoms . Far beneath the ruined capital city of Lordaeron , the royal crypts have been turned into a bastion of evil and undeath . Originally intended by Prince Arthas to be the Scourge ' s seat of power , the budding " Undercity " was abandoned when Arthas was recalled to aid the Lich King in distant Northrend . In Arthas ' s absence , the Dark Lady , Sylvanas Windrunner , led the rebel Forsaken to the Undercity , and claimed it for her own . Since taking up residence , the Forsaken have worked to complete the Undercity ' s construction by dredging the twisted maze of catacombs , tombs , and dungeons that Arthas began . History . The Undercity was so named many years before the Forsaken claimed it as their own . Far beneath the palace of Lordaeron , the Undercity held the ancient crypts and catacombs of Lordaeron ' s royalty , as well as the city ' s dungeons and sewers . Although the Undercity was only intended for prisoners and the dead , the poorest of the Lordaeron people lived within . When the Alliance captured Orgrim Doomhammer , they sent him to the Undercity ; sometime later he managed to escape and wandered for many years afterwards . Lordaeron ' s capital city stood for centuries , a monument to humanity ' s might . In the Third War , Prince Arthas slew his father , King Terenas , in Lordaeron ’ s throne room and ransacked the city . He planned to use Lordaeron as his capital on this continent and ordered his minions to expand the catacombs beneath the city . Then the Lich King summoned Arthas to Northrend and the work was left uncompleted . During Arthas ' exodus , Sylvanas Windrunner broke free of the Lich King ’ s control and took many banshee s and other undead with her . With Varimathras ' assistance she defeated the dreadlord s that controlled the city and set her newly dubbed Forsaken to finish Arthas ' job in the dungeons . The Forsaken carved the Undercity and now rule the surrounding countryside . While the forces of the Horde and the Alliance were concentrated on a joint effort at Angrathar the Wrathgate , an uprising broke out within the Undercity . Demons of the Burning Legion and Forsaken rebels led by the dreadlord Varimathras and Grand Apothecary Putress managed to take control of the Undercity , killing several Forsaken and nearly killing the Dark Lady as well . In response the Horde led by Sylvanas Windrunner and Warchief Thrall attacked from the front entrance to reclaim the city . While the Alliance led by Varian and Jaina attacked from Sewers to restore Lordaeron to the Alliance . The ensuing battle ultimately killed both Varimathras and Putress , along with their fellow demons and Forsaken rebels . Wrath of the Lich King . However being no stranger to broken dreams , it is only fitting that Lordaeron bore witness to the end of the Horde - Alliance treaty as King Varian declared war upon the Horde after seeing the status of the once proud city . Jaina subsequently teleported the Alliance back to Stormwind . With Patch 3 . 3 . 0 , Thrall sent a legion of Kor ' kron Guard led by captain Bragor Bloodfist , who replaced Varimathras , with Kor ' kron Overseer s replacing the Undercity Guardian s , in order to ensure that the events of the Battle of Angrathar the Wrathgate never occur again . Some guardians still remain in the Sewers ; it ' s unknown if this is an error or not . Stormrage . After the death of Arthas , the Undercity was attacked by the Emerald Nightmare ' s mists and shadowy warriors of nightmares . Sylvanas , half of the Forsaken and all Horde representatives were having nightmares . Sharlindra and some Forsaken witnessed Sylvanas ' murmur and moments later , shadowy figures attacked Sharlindra and her followers - thus the whole Undercity was enveloped by the Nightmare . World of Warcraft : Cataclysm . In " " , the Undercity was " redesigned to accommodate flight . " , as seen on the image to the left . The city has been fleshed out from its original " cardboard cutout " setup and is now a complete edition of the broken Lordaeron . Geography . The Undercity is an extension of the crypts and dungeons originally beneath Lordaeron ' s capital city . The Forsaken dredged out complex catacombs and caverns . The place is dark , smells of corpses and has an evil feel . Spiders , oozes and other subterranean creatures occupy the distant passages . It is drastically different from any of the other capital cities for the Horde . Unlike Thunder Bluff and Orgrimmar , which are at the surface and often the sites of multiple festivals , the Undercity is dark , dreary , and cold . The Forsaken , however , are known for holding two festivals , Hallow ' s End and Pilgrim ' s Bounty . Quarters . The city is made up of roughly symmetrical quarters arranged around a circular center . Orb of Translocation . Since the release of " The Burning Crusade " , players with the expansion are able to access an Orb of Translocation to the Silvermoon City palace , making it easy for anyone to travel between the two cities without having to go through the Plaguelands . The translocator works both ways . The Undercity orb is located in a newly opened city section west off the main part of the Ruins of Lordaeron . The translocator teleports you to the Inner Sanctum of the Sunfury Spire within Silvermoon City . It cannot be used by the Alliance . King Terenas ' tomb . It is unknown who constructed the memorial to Terenas . It ' s possible that some Forsaken , feeling some residual loyalty to Lordaeron did it . It could also have been the members of the Silver Hand from when they retrieved Terenas ' body . Another possibility is that the remaining Alliance forces in Lordaeron under Garithos erected the memorial during the short time that they controlled Capital City before Sylvanas took control . It is also unclear what the tomb actually contains , since Terenas was cremated and his ashes were scattered by the wind . Voices In The Throne Room . Some may note they hear whispers and voices throughout Undercity , but within three areas in the Ruins of Lordaeron , there is significant words spoken . All of these sounds relate back to Warcraft III , in which Arthas returned to Lordaeron and killed his father , King Terenas . In the area where the bell is , you can hear the bell ringing in the ambiance , signifying Arthas ' return . Upon moving from the bell tower to the hall before the throne room , the ambiance heard is the cheers of the People of Lordaeron welcoming Arthas back home . Upon the ground is dead rose petals , significant from the cutscene in Warcraft III in which the citizens showered Arthas with them as he walked to the throne room . Upon entering the throne room , multiple voices are heard , the first being King Terenas and the warning given by the prophet , Medivh . Soon after , you hear the exchange between Arthas and his father as he kills him . The blood stain of the crown falling on the floor from Warcraft III can also be seen on the floor near the throne . The following are the lines heard , which come in 5 separate waves . To best be heard , turn off your music and sounds , leaving only ambiance on and turned up . For those who want to hear this without venturing to Undercity , it was once possible to hear the sound by going into the data files , however , with the new file structure implemented by Blizzard this sound can only be heard by typing the following : / script PlaySoundFile ( " Sound \ \ Ambience \ \ WMOAmbience \ \ UnderCityThorneRoom . wav " ) It may be easier to execute this by using a macro , as to make sure you don ' t misspell anything . Also , this is considered a sound when executed this way , so you must have your sound on and nothing else to hear it best . Below are the two cutscenes where the voice clips are taken from . Notable characters . From her throne in the Royal Quarter , the banshee queen Lady Sylvanas Windrunner rules with the support of the dreadlord Varimathras ( Bragor Bloodfist , post - Battle for the Undercity ) and the ghostly Sharlindra . Other luminaries include Bethor Iceshard , who is a powerful wizard that heads the joint warlock and mage guilds in Undercity , and Master Apothecary Faranell of the Royal Apothecary Society .
