Located within the Twilight Highlands, the Twin Peaks remains a crucial point of high ground for staging effective and debilitating attacks against the black dragonflight and the Twilight's Hammer, who dominate this foreboding environment.
As with Uldaman and Ulduar, Uldum houses one of only a few of the known titan constructions, the existence of which predates that of mortal life on Azeroth. For years historians have explored southern Kalimdor for a means of entry into this ancient titan land, searching for more evidence of Azeroth's origins. But the Cataclysm will change everything, for the façade behind which Uldum has been tucked for millennia will be ruptured, leaving powerful mysteries vulnerable to discovery by the bravest, smartest, or perhaps even most brutal explorers.
After years in exile, the Darkspear trolls are preparing to invade the Echo Isles and reclaim the land once bestowed to them by Thrall. Led by Vol'jin, a wise and highly regarded Darkspear, the tribe's bravest warriors will set out from Orgrimmar and Sen'jin Village, seeking to bring about Zalazane's fall and begin the process of rebuilding their homes and villages on the Echo Isles. In World of Warcraft: Cataclysm, new troll adventurers will begin their journey on these tiny islands off the coast of Durotar, where they'll be able to experience this time of trial and transition firsthand.
Once a great Highborne city housing some of the most revered night elves of Kalimdor, Vashj'ir was swallowed by the Great Sea during the Sundering and thought to be lost forever. Queen Azshara, formerly a beloved leader of the night elves, escaped death in the depths of the sea when the Well of Eternity imploded. Such salvation came at a great cost, as the queen and many of her fellow Highborne were forever transformed into the monstrous naga, doomed to wander the seas for thousands of years. Their existence mostly remains a mystery to the peoples of modern Azeroth, though the Earthen Ring has learned of Azshara's naga seizing Vashj'ir for an unknown purpose as the cries of the elements echo across Azeroth from the abyss.
For years, Mount Hyjal and the wounded World Tree, Nordrassil, have remained cut off from the rest of Azeroth. Sealed away within a protective field of dense foliage by Malfurion Stormrage, Nordrassil has been slowly recovering from the devastation of the Third War, when Malfurion called upon the tree's power to destroy the archdemon Archimonde and repel the forces of the Burning Legion and Scourge. Now, with the impending cataclysm, the World Tree's well-being is threatened once more. From the Firelands within the Elemental Plane, Ragnaros and his minions prepare to burst into Hyjal and set Nordrassil ablaze -- and the conflagration would endanger all life on Azeroth.
