Mists of Pandaria: Wowhead previews Vale of Eternal Blossoms
The Vale of Eternal Blossoms is the zone for max-level players to hang out and get their endgame faction work done. The Alliance and Horde each have their own settlements, which have every thing you would look for in a major city while also including many level 90 faction hubs.
The catch is that the only way to get into the vale is to complete a quest chain for the August Celestials, A Celestial Experience. At the Kun-Lai Summit, you must complete the trials of Xuen the White Tiger in order to gain access.
