Kel'Thuzad is back on the screen in Blizzard Entertainment's Warcraft III Reforged: Forsaken Kingdom, the campaign Blizzard released at BlizzCon 2026 in September. Blizzard's panel recap lists him among the familiar figures in the story, alongside Sylvanas Windrunner, Arthas, Ras Frostwhisper and Baron Rivendare. His history runs from the Kirin Tor of Dalaran through the Cult of the Damned and his rebirth at the Sunwell to 2 defeats in Naxxramas. Check out the official post down below:
Kel'Thuzad's original story runs through Warcraft III: Reign of Chaos (2002), Warcraft III: The Frozen Throne (2003) and the 2 versions of the Naxxramas raid in World of Warcraft, ending with Wrath of the Lich King. Blizzard's World of Warcraft: Chronicle Volume 3 (Dark Horse Books, 2018) and Christie Golden's 2009 novel Arthas: Rise of the Lich King retell parts of his life, and several of their details differ from the Warcraft III version.
An Archmage Of The Kirin Tor
Before the Second War, Kel'Thuzad sat on the Council of Six, the ruling council of the Kirin Tor in Dalaran. In the novel Tides of Darkness, he is the council member most eager to reach the Guardian's Library, the collection of knowledge Medivh kept in his tower of Karazhan, and he presses Medivh's apprentice Khadgar for details about the Order of Tirisfal after Medivh's death. In Cycle of Hatred, Jaina Proudmoore meets him in her third year as an apprentice, when Antonidas introduces him as one of the finest mages in the Kirin Tor.
Chronicle Volume 3 adds an origin for his interest in necromancy. Kel'Thuzad saw the Horde's death knights during their raid on Dalaran before the invasion of Draenor, and what their magic could do pulled him further into the subject. Warcraft III's own manual gives no single moment and describes him as a maverick who had studied the forbidden arts for years and considered his peers' rules outdated.
The Arthas novel dates his fall from the Kirin Tor to about 5 years before the Third War. In Golden's version, Antonidas learns that Kel'Thuzad has been reanimating dead rats, has his properties searched and destroys everything tainted by dark magic, then warns him that he will lose his rank and holdings and be exiled from Dalaran and Lordaeron if he does not stop. Kel'Thuzad leaves Dalaran, sells his holdings and stores away his fortune.
The Call Of The Lich King
A handful of powerful people across the world heard the Lich King's mental summons from Northrend, and Kel'Thuzad was the first to answer it. In the Warcraft III manual, he crosses land and sea alone, passes through the ruins of the nerubian kingdom of Azjol-Nerub, and spends months crossing the arctic wastes to Icecrown. The undead guards of the citadel let him pass, and at the bottom of the glacier he kneels before the Frozen Throne and offers his soul to Ner'zhul.
The Lich King promises him immortality and power in exchange for his loyalty and gives him his first mission: return to Lordaeron and found a new religion that worships the Lich King as a god. Ner'zhul leaves Kel'Thuzad's humanity intact for the job, so the aging but still charismatic wizard can win over the poor and the overworked with his powers of illusion and persuasion.
Blizzard added a stop to that trip in 2006. Road to Damnation, a short story by Evelyn Fredericksen published on the World of Warcraft site for patch 1.11, has the crypt lord Anub'arak meet Kel'Thuzad in Northrend with the words "The master has been expecting you, archmage." Anub'arak leads him through a nerubian ziggurat called Naxxramas, wing by wing. Kel'Thuzad is frightened by what he sees, teleports out and tries to escape, but wraiths surround him and bring him back inside. The Warcraft III manual has no Naxxramas visit.
Chronicle Volume 3 also moves the date of the Road to Damnation events. The official 2004 timeline placed Kel'Thuzad's summons in Year 18, while Chronicle places it after Year 15 and before Year 18.
The Cult Of The Damned And The Plague
Kel'Thuzad returned to Lordaeron in disguise and spent 3 years using his fortune to build a secret brotherhood he called the Cult of the Damned. The cult promised its acolytes social equality and eternal life in exchange for serving Ner'zhul, and most of its early members came from Lordaeron's overworked laborers. On Caer Darrow, he made a deal with the Barov family that moved cultists into the Scholomance, and he brought his friend Baron Rivendare into the cult.
The Lich King then placed his plague in portable artifacts called plague cauldrons, and Kel'Thuzad had them hidden in villages the cult controlled. Andorhal, the distribution center for the farm goods of Lordaeron's northern provinces, became the center of the operation. Plagued grain went out from Andorhal to the villages along the King's Road and to towns such as Hearthglen and Stratholme. People who ate it died and rose as the Lich King's servants, and Kel'Thuzad gave the growing army its name, the Scourge.
Chronicle Volume 3 says the plagued grain looked like normal grain and gave no sign of corruption until days after it was eaten. The Culling of Stratholme dungeon in Wrath of the Lich King handles it differently: Chromie says the infinite dragonflight cast illusions on the plagued shipments to make them appear normal, so that Arthas' men cannot find them.
Death At Andorhal
Warcraft III's Human campaign brings Prince Arthas and Jaina Proudmoore into the outbreak. They catch Kel'Thuzad in Brill, and he flees to Andorhal, where the Human mission The Cult of the Damned has the 2 confront him in the town center. He greets them with "Hello again, children. I am Kel'Thuzad, and I've come to deliver a warning. Leave well enough alone. Your curiosity will be the death of you."
Kel'Thuzad admits that he ordered the cult to distribute the plagued grain and says he serves the dreadlord Mal'Ganis, who commands the Scourge. He tells Arthas to seek Mal'Ganis at Stratholme. Arthas hunts him down and kills him, and Kel'Thuzad's last words are "Naive fool. My death will make little difference in the long run. For, now, the scourging of this land... begins."
Reborn At The Sunwell
After Arthas takes up Frostmourne and returns to Lordaeron as a death knight, the Undead campaign sends him back to Andorhal. In the mission Digging up the Dead, he cuts through the paladins of the Silver Hand guarding the cemetery where Kel'Thuzad was buried, and Uther the Lightbringer dies in the fighting. Gavinrad the Dire calls him a spoiled prince who has made a mockery of the order. At the tomb, Kel'Thuzad's ghost appears beside Arthas and says, "Told you my death would mean little."
The dreadlord Tichondrius tells Arthas that the remains are too decomposed to survive the trip to Quel'Thalas, and that only the energies of the high elves' Sunwell can bring Kel'Thuzad back. Arthas has to take the Urn of King Terenas from the paladins to carry them. On the road, the ghost tells Arthas that the dreadlords cannot be trusted because they are the Lich King's jailors, and he promises to explain everything once he walks the earth again.
Chronicle Volume 3 tells this part in a different order. In Chronicle, Arthas kills Uther and then recovers Kel'Thuzad's remains inside Andorhal, while in Warcraft III Kel'Thuzad died outside the city and Arthas killed Uther for the urn while recovering the remains on the outskirts of Andorhal.
Arthas breaks through the 2 Elfgates of Quel'Thalas, takes Silvermoon and places the remains in the Sunwell. With Tichondrius' help, Kel'Thuzad rises as a lich and declares, "I am reborn, as promised! The Lich King has granted me eternal life!" The well itself is covered in GB Lore Corner: How The Sunwell Rose, Fell And Returned In Warcraft.
Summoning Archimonde
With his body restored, Kel'Thuzad tells Arthas the truth behind the plague. The Lich King was created by the Burning Legion to prepare Azeroth for invasion, and the dreadlords were sent to make sure he succeeded. Kel'Thuzad says the Lich King knew Arthas would kill him in Andorhal and had chosen Arthas as his champion before the Scourge began.
At a Demon Gate in Alterac, Kel'Thuzad contacts the eredar Archimonde, who tells him to steal the spellbook of Medivh from Dalaran and begin the summoning 3 days later at twilight. Arthas leads the attack on Dalaran and kills Antonidas, and Kel'Thuzad reads through the book while preparing the ritual, saying Medivh's knowledge of demons was staggering. Archimonde steps through the portal, hands command of the Scourge to the dreadlords and leaves to destroy Dalaran. When Arthas asks what happens to them now, Kel'Thuzad answers, "Be patient, young death knight. The Lich King foresaw this as well."
Kel'Thuzad then sends Arthas to Kalimdor. The Arthas novel has him teleport the death knight to Felwood, directly to Illidan Stormrage, after telling him about Illidan. Chronicle Volume 3 instead says Arthas went to Kalimdor with the demons on the Lich King's orders and secretly worked against the Legion there before he found and manipulated Illidan on his own.
The Frozen Throne And The Plaguelands
The Frozen Throne's Undead campaign, Legacy of the Damned, returns Arthas to Lordaeron, where Kel'Thuzad has held the capital as one of the Lich King's lieutenants. Arthas chases the dreadlords out of the city, and the 2 then attack human refugees fleeing through the mountain passes. When the dreadlords ambush them, Kel'Thuzad escapes on his own, then saves Arthas from Sylvanas Windrunner and her banshees with the line "Back, you mindless ones! You shall not fall today, my king."
Kel'Thuzad escorts Arthas to a fleet he has prepared for the trip north. Arthas calls him a loyal friend and tells him, "I want you to watch over this land. See to it that my legacy endures." Kel'Thuzad answers, "I shall, King Arthas, I shall." While Sylvanas and the Forsaken take Tirisfal Glades, Kel'Thuzad rules the Eastern Plaguelands from the floating necropolis of Naxxramas.
Forsaken Kingdom is set in the 4 years between Warcraft III and World of Warcraft, and Blizzard says it explains how the Undercity was established and why the Scourge did not reclaim Lordaeron. Blizzard lists about 30 hours of gameplay and nearly an hour of in-game cinematics.
Blizzard's launch trailer for Forsaken Kingdom is below:
Kel'Thuzad also created the Four Horsemen, elite death knights who served as his royal guard, and the frost wyrm Sapphiron guarded his chamber. The Ashbringer comic fills in how the first leader of the Horsemen was made. Renault Mograine killed his father, Highlord Alexandros Mograine, with the Ashbringer under the influence of the dreadlord Balnazzar, and Kel'Thuzad took the body and blade and raised Alexandros as a death knight.
Shadow Of The Necropolis
Naxxramas opened in World of Warcraft with patch 1.11, Shadow of the Necropolis, in June 2006. The 40-player raid floated above the Plaguewood in the Eastern Plaguelands, and players needed Argent Dawn attunement to use the teleport spire in the Plaguewood that led inside. The necropolis was split into 4 wings, the Arachnid, Construct, Plague and Military Quarters, and clearing all 4 opened the Frostwyrm Lair, where Sapphiron and Kel'Thuzad waited.
The Kel'Thuzad fight ran in 3 phases. Killing his cat, Mr. Bigglesworth, triggered the line "No!!! A curse upon you, interlopers!" In the last phase he calls out "Master! I require aid!", and the Lich King answers by ordering the warriors of the frozen wastes to rise and fight. On death, Kel'Thuzad warns, "Do...not...rejoice! Your victory is a hollow one, for I shall return with powers beyond your imagining!"
Michael McConnohie voiced Kel'Thuzad in Warcraft III and in the original Naxxramas. He also voiced the Lich King, and Blizzard had a different actor re-voice Kel'Thuzad's lines for Wrath of the Lich King. The patch 1.11 trailer retells the Road to Damnation story in Kel'Thuzad's words, from "I was cast out by my comrades" to "Your curiosity will be the death of you." The trailer is on the official World of Warcraft YouTube channel:
His death was not permanent, because a lich can reform through his phylactery. The quest The Fall of Kel'Thuzad starts from the Phylactery of Kel'Thuzad and sends players to Father Inigo Montoy at Light's Hope Chapel instead of destroying it. The phylactery never reached the Argent Dawn, and a traitor in the order fled to Northrend with it. Chronicle Volume 3 adds the Alliance side of the first defeat: after the Scourge attacked Stormwind City in the first Scourge invasion, Bolvar Fordragon recruited Alliance heroes who raided Naxxramas and killed Kel'Thuzad.
Naxxramas Over Dragonblight
Patch 3.0.2 removed the 40-player raid on October 14, 2008, and Wrath of the Lich King launched on November 13, 2008, with Naxxramas rebuilt as the introductory level 80 raid in 10-player and 25-player versions. The necropolis now floated above the Carrion Fields in Dragonblight, besieging Wintergarde Keep. Montoy's hoarding of the phylactery had let Kel'Thuzad regain his body, and Montoy appears below the keep in the Wintergarde Mausoleum as the lich Thel'zan the Duskbringer.
Horde players also find Kel'Thuzad in the Borean Tundra. The quest The Plains of Nasam sends them out in a siege tank to identify the Scourge leader in the area, and Kel'Thuzad stands on a dais surrounded by stitched horrors and plague spreaders. Inside Naxxramas, he had appointed Baron Rivendare to replace Alexandros Mograine as the 4th Horseman.
The Wrath fight follows the original, with the Lich King answering the same call for aid, and players defeat Kel'Thuzad a 2nd time. The official accounts of that raid disagree on who went in. The short story Glory says the Alliance assaulted Naxxramas while the Horde invaded Azjol-Nerub, and Chronicle Volume 3 says champions of both the Alliance and the Horde attacked Naxxramas. Blizzard's cinematic trailer for the expansion is below:
Which version of Kel'Thuzad's recruitment do you prefer, the Warcraft III manual's walk straight to the Frozen Throne or Road to Damnation's detour through Naxxramas with Anub'arak?
