Speak to Dezco at the Temple of the White Tiger in Kun-Lai Summit.
Have you heard the news, traveller? There's been an attack at one of our most sacred places, the Vale of Eternal Blossoms!
Even now, there's a human prince within the White Tiger Temple arguing that you and the other races from beyond the mists should be allowed within.
The temple is in the northeast of Kun-Lai. Maybe you can convince the White Tiger to allow you inside?
I only hope the Vale has not been utterly destroyed...
