Kel'Thuzad's Chamber



Kel'Thuzad's Chamber is the final room of Naxxramas and the inner sanctum of its dread master. It is only reachable after defeating Sapphiron.

Trivia

 * The doors all around the chamber actually lead to a snow-filled area that has been partially copy-pasted from Winterspring. While the detail doesn't matter much in the version of Naxxramas flying over the Dragonblight, for the original one that was flying over the Eastern Plaguelands it hinted (years before the release of Wrath of the Lich King) that they were portals toward the continent of Northrend, something strongly implied with the Soldiers of the Frozen Wastes and Guardians of Icecrown mobs that were pouring out of them.
