Andorhal The city of Andorhal ( Andorhall ) is a destroyed human city located in the Western Plaguelands , formerly one of the largest cities in northern Lordaeron . Today , the ruined city is firmly in the Scourge ' s grip , with a population of 30 , 120 , mainly undead . After several years though , Andorhal becomes a battleground between the Horde and the Alliance with the remaining Scourge forces trapped in - between . The Alliance side has been slightly rebuilt and the Horde side is decimated by the Forsaken ' s chemicals and potions . Beneath Andorhal is the School of Necromancy , a sprawling subterranean labyrinth akin to the Undercity but on a much smaller scale . The waters around Andorhal are contaminated by the Plague of Undeath . History . Scourge invasion . Andorhal was once the distribution center for all agricultural supplies in the northern provinces of Lordaeron east of Lordamere Lake before the Third War . It was used by Kel ' Thuzad to spread the plague , infecting the grain there , which was sent to different northern towns . Andorhal was gripped by the original outbreak of the Plague of Undeath , but remained uncontrolled by Scourge agents . Kel ' Thuzad was initially defeated by Arthas in Andorhal . However , Andorhal fell at the hands of Arthas when he returned here to claim the remains of Kel ' Thuzad for reanimation , therefore falling under Scourge control . Following the defeat of the Burning Legion and the consolidation of the Western Plaguelands by the Scourge , Andorhal became a regional bastion effectively separating the lands of the Lich King from those still under mortal control . Later , Andorhal became the headquarters of the lich Araj the Summoner who used the ruined city as the base of operations , from which he oversaw the use of the mighty plague cauldrons situated throughout the Western Plaguelands . The roads leading north out of Andorhal are occasionally patrolled by forces of the Scarlet Crusade — either survivors of Andorhal or troops sent from nearby Hearthglen . Failed Retaking of Andorhal . During the time of The Burning Crusade , Andorhal was invaded by Maddox and an army of mercenaries and the Argent Dawn . However , the army consisted in just 100 soldiers and were easily beaten by the Scourge . Cataclysm . Due to the Argent Crusade cleansing of Western Plaguelands . Most of the Scourge Reformed To Andorhal . Andorhal has become a warzone between the Alliance and the Forsaken under the command of Thassarian and Koltira Deathweaver respectively . Araj the Summoner leads what remains of the Lich King ' s forces in Andorhal , their power diminished by the death of their lord . During the Battle for Andorhal ' s beginning , the Alliance establish a hold on the South - Western side of the city , reinforced by Chillwind Camp . The Forsaken have a strong front on the North - Eastern side of the town . The combined forces relentlessly slaughter Scourge and ultimately slay Araj . Thassarian and Koltira exchange pleasantries , and give each other time before they must ultimately come to battle with one another . Shortly after , battle is joined , with Alliance militiamen taking the field , having come North in hope of farmland that was promised , yet unavailable . Despite this advantage , it is revealed that Sylvannas has been observing the battle , and will not have it lost . Using Val ' kyr , she turns the tide of battle , forcing the Alliance to flee . Despite the Forsaken victory , Sylvanas Windrunner is displeased with what she perceives as weakness on Koltira ' s part , knowing of his long - standing comradeship with Thassarian and the truce they made in the field . Confronting him after the victory , Sylvanas has Koltira taken to the Undercity so that he can be made to serve the Horde - or , more specifically , the Forsaken - exclusively , without any regard for his prior service to the Knights of the Ebon Blade .
