World of Warcraft: Cataclysm Twilight Highlands Preview

Blizzard provides a first look at a new high-level zone in the upcoming Cataclysm expansion, called the Twilight Highlands.
The highlands have undergone constant upheaval throughout their history, with races and factions thriving, collapsing, and changing seemingly without pause. The fortress-city of Grim Batol has played host to no fewer than three potent factions: the Wildhammer dwarves, who abandoned their home after a Dark Iron curse left it uninhabitable; the red dragonflight, which was forced to fight for the Horde in the captivity of the Dragonmaw orcs during the Second War; and, of course, the Dragonmaw themselves, who were driven from Grim Batol when the red dragonflight was finally freed from their grasp.
