The End Is Near

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, nursing his hatred for the inferior creatures that infest the surface realm...and biding his time until he can reforge the world in molten fire.
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 massive monstrosity before you rises up like a black, crag-covered mountain of scales and hide. The head is a spade-like terror spiked with cruel red eyes that shine with a frightening malevolence. Rivulets of lava and magma are visible beneath the great wyrm's scorched scales.
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.
Deathwing, the Destroyer, originally Neltharion, the Earth-Warder, is one of five Dragon Aspects and leader of the black dragonflight. Thousands of years ago, Neltharion was empowered by the Titan Khaz'goroth with dominion over the earth and the deep places of Azeroth. However, driven mad by the Old Gods, he turned against the other Aspects during the War of the Ancients, capturing a portion of their power in the Demon Soul. Among both humans and dragons his name has become one whispered with a feeling of fear and contempt.
Few have fallen as far from grace as ancient Neltharion has. As one of the five Dragon Aspects chosen by the titans, he was given dominion over the earth and the deep places of the world. He embodied the strength of Azeroth and served as the greatest supporter of the Dragonqueen, Alexstrasza. But mighty, kind-hearted, and wise as he was, even Neltharion was not beyond the reach of dark forces sleeping beneath the surface of Azeroth. Over time, sinister whispers sank their claws into the dragon's thoughts, seeding Neltharion's mind with madness. He betrayed the other Aspects, and when he turned against his brethren and let corruption take complete control, he ceased being Neltharion the Earth-Warder and became Deathwing the Destroyer. Eventually, he was defeated by the combined might of the other Aspects-defeated, but not destroyed. Hidden from the world, he has been licking his wounds and nourishing his burning hatred. His return will change the face of Azeroth... forever.
