About World of Warcraft® Cataclysm Expansion Cataclysm™ is the third expansion set for the MMORPG game, World of Warcraft®. While the attention of the Horde and Alliance remained fixed upon Northrend, an ancient evil has been lying dormant within Deepholm, the domain of earth in the Elemental Plane. Hidden away in a secluded sanctuary, the corrupted Dragon Aspect Deathwing has waited, recovering from the wounds of his last battle against Azeroth. Soon, Deathwing the Destroyer will return to Azeroth, and his eruption from Deepholm will sunder the world, leaving a festering wound across the continents. As the Horde and Alliance race to the epicenter of the cataclysm, the kingdoms of Azeroth will witness seismic shifts in power, the kindling of a war of the elements, and the emergence of unlikely heroes who will rise up to protect their scarred and broken world from utter devastation. The face of Azeroth is altered forever as the destruction left in Deathwing’s wake reshapes the land and reveals secrets long sealed away. Players will be able to re-experience familiar zones across Kalimdor and the Eastern Kingdoms, rewrought by the cataclysm and filled with new opportunities for adventure.
