Noth the Plaguebringer

Noth the Plaguebringer is the first boss of the Plague Quarter in Naxxramas. Once a notable wizard and alchemist of Dalaran, Noth heard the Lich King's call as Arthas and Kel'Thuzad did. He was quick to turn his back on the Light and joined the Scourge, where he believed that real power lay. During the Third War, Noth saw that many innocent lives were needed to feed the growing might of the Scourge and he came to a point where he started opposing himself. Kel'Thuzad resolved the matter by freezing his heart in his chest with his frost magic. Noth the Plaguebringer, now more undead than human is an extremely powerful necromancer with a various array of deadly spells and curses.
