Tempest Keep, Eye of the Storm key
Questline starts in Shadowmoon Valley at a guy named "Oronok Torn-heart"
First you do some small quests for him, then he sends you out to find his 3 sons.
After you have found them and done all quests you get a quest to kill a golemagg-lookalike (5 man group)
When you have done that Oronok Torn-heart sends you to Shattrath City and there you can
pick up 3 quests and in all 3 it stands like this:
"Four trials you must pass before you are deemed worthy of the Tempest key"
"Trial of the Naaru: Mercy (Heroic)" Completes in Shattred Halls, Heroic
"Trial of the Naaru: Strength (Heroic)" Completes in Steamwault and Shadow Labyrinth, Heroic
"Trial of the Naaru: Tenacity (Heroic)" Completes in Arcatraz, Heroic
After all this is done, you get the Tempest Key
Caverns of Time, Mount Hyjal questline
First you need to save Thrall in Durnholde keep after that is done you can do Black Morass
In Black Morass you can take a quest from a guy in the beginning of the instance and when
you have killed the last boss in that instance and completed it, you can take the quest:
"The Vials of Eternity (raid)" just outside Black Morass.
Completes in Eye of the Storm(Tempest Keep) and Serpentshrine Cavern(Coilfang Reservoir)
After this is done, you will most likely get the key to Mount Hyal
