Kirel narak! I am Mal'Ganis! I AM ETERNAL!
~ Mal'Ganis

Mal'Ganis was the main antagonist of the human campaign in Warcraft III: Reigns of Chaos, and a supporting character in World of Warcraft: Wrath of the Lich King.


Mal'Ganis worked with Kel'Thuzad to spread a deadly plague of undeath throughout the entire kingdom of Lordaeron. When Kel'Thuzad was killed by Arthas Menethil and Jaina Proudmoore, Mal'Ganis was left to continue the spreading of the deadly disease through one of the kingdom's largest cities - Stratholm. Arthas, along with a group of loyal soldiers, raided Stratholm and murdered all of its inhabitants before they could succumb to Mal'Ganis's evil plague. Arthas and Mal'Ganis finally met face to face, and the two had a short battle. Not long later, Mal'Ganis escaped to the frozen wastelands of Northrend, the homeland of the living dead.

Arthas and an entire army of soldiers chased Mal'Ganis to the north, where they fought his undead legions. Arthas and his friend, Muradin Bronzebeard, came across a mystical sword called Frostmourne, which Arthas took as his own and used it in battle. Arthas and Mal'Ganis met once again near the sacred Troll temple known as Drak'tharon Keep. In their final battle, Arthas thought he had killed the demon, but it was far from over...

Years later, during the War in the Frozen Wastes, Mal'Ganis returned disguised as the human, Admiral Barean Westwind. He used this disguise to secretly rule over the Scarlet Onslaught and use them as his puppets until he could kill Arthas, now the Lich King, and have his revenge. Unfortunately, a rebel group of Death Knights known as the Knights of the Ebon Blade learned of his presence and sent in adventurers to put an end to his evil. The adventurers assaulted Admiral Westwind's hideout and killed many of his most powerful warlocks. Westwind and the heroes had an epic battle, and Mal'Ganis was forced to remove the disguise so that he could be at full power. He was defeated, but escaped to the Twisting Nether, swearing revenge on the Lich King AND them.

When the Infinite Dragonflight sent in a strike force back in time to the raid on Stratholm in an attempt to kill Arthas, the Bronze Dragonflight sent 5 heroes to the same time to defeat the Infinites. They aided Arthas in fighting Mal'Ganis's evil minions, and eventually fought the demon himself. In the end, Mal'Ganis escaped to Northrend, and time itself was saved.
