Obtain 20 Mogu Archaeology Fragments.
Ah, an explorer. Just what I could use. I am on the verge of discovering the dark secrets of the mogu.
Not all of the secrets, mind you. They kept a lot of dark secrets. But I am on the verge of discovering "a" secret at least.
If, in your travels, you come across some fragments of the mogu past, bring them to me and I will happily reimburse you for them.
