Here is all that i've found (directly relevant with any doubts to have) :
"These are fanatics, believing this Vault holds one of their greatest legends: The Grey One."
"The Grey One was a drogbar so evil, Neltharion encased him in stone as a lesson to us all. We must not let these zealots free him."
"Crok! The Grey One has been unleashed. We must get out of here before the vault's defenses return."
"You are too late, karkrun! The Grey One shall be free!"
"Even Deathwing could foresee the evil that the Grey One could unleash if left unchecked.This is a grim day for us all."
"Spiritwalker! What has happened here?"
"The Grey One. He came and... I am sorry my Chieftain. But the Grey One has taken your father's body."
"When you reach the spirit realm, tell your master that he'll never be set free so long as I breathe."
"Your time in this life is short. The Grey One has seen it."
"Let us rest!";"Let us rest!"
"I have seen it! The Grey One approaches!";"I have seen it! The Grey One approaches!"
"The darkness rises."
"The Grey One will pierce the veil."
"Embrace the shadow."
"He will return."
"Dark overcomes light."
"Accept the Grey One."
"He is master of shadows."
"Quickly hero, I can open a portal to the spirit world but you must move quickly before the Grey One can escape."
So... it looks like the Grey One has stolen the Ulan Hightotem's body, which is the father of Mayla High Chieftain of Highmountain.
Now look Ulan's skin : wowhead.com/npc=105211/ulan-highmountain
