This is just a patch for the awesome XMage_Portals addon by Xcrystal all it does is add Valley of Eternal Blossoms to your Port/Teleport list.
The download only contains 1 file please copy this file into your "World of Warctaft\Interface\AddOns\XMage_Portals" folder.
Not playing WoW atm but it should still work leave a comment if it dosn't work or wait until xcrystal updates the main addon.
