Blizzard has just announced that a new dungeon will be introduced into World of Warcraft in patch 3.3.5. The Ruby Sanctum is the final Wrath of the Lich King dungeon and a precursor to the events of World of Warcraft: Cataclysm.
"Wyrmrest Temple has been breached. The Ruby Sanctum, hallowed domain of the red dragonflight in Northrend, is under siege.
"Now, the mighty dragons must rely on the mortal races for salvation. The fate of the red flight, caretakers of all life on Azeroth, hangs in the balance. Stalwart champions, Horde and Alliance alike, will rush to the defense of the sanctum. Will you be among them?"
