World of Warcraft: Mists of Pandaria | Zone Preview: The Wandering Isle

Separated from Pandaria for millennia, the Wandering Isle meanders the oceans of Azeroth. When the weather changes unexpectedly on the Isle and it begins erratically spiraling toward the Maelstrom, the elders at the Temple of Five Dawns request the aid of four elemental spirits to unravel the mystery. Heroes must figure out the cause of the land's illness before the entire island plunges into the abyss!
 
It is the rare pandaren indeed who sought a way beyond the mist. Generations ago, pandaren explorers began to gather on the back of a giant turtle: Shen-zin Su. The great sea turtle roamed Azeroth's oceans, perhaps the only contact pandaren had with the outside world. Eventually, they too lost contact with their mist-shrouded homeland.
 
Players who choose to create a pandaren character will start their journey on the back of Shen-zin Su. When the great turtle is threatened, and their whole wandering homeland is in jeopardy of being swallowed by the sea, players will have to accelerate their training and spring into action.
 
During their time on the turtle, players will first encounter the Alliance and Horde. Before they are finished, they'll have to make the most important decision of their lives: Which of the two factions will they support as they venture out to heal a world broken by the Cataclysm and threatened by a global war?
