Upper Blackrock Spire Key

From: http://wow.allakhazam.com/db/quest.html?wquest=4742

Get Quest or Hand in.
Enter Foyer.
Right hand side up ramp and turn right.
Stop at ledge and watch for Pat.
Jump down left side of ledge.
Down ramp and turn left and follow corridor.
Come into large room hard left to wall.
(note if you want to see where you have to then hard right. Look up and diagonally across room to about halfway point. You will see the quest giver/returner x2 up on a ledge. Look to the right and on same level as you are. There is a stone face slope you can make out beyond the flat wall. You need to go up that to it's far corner where you can jump up to same level as Valean.)
If you are 60 hug the left wall all the way around you will not aggro, the 55 that came with me did aggro the mob.
(So enter room hard left you will be safe either right or left no mobs there. Hug left wall turn left hug, turn right, hug, turn left to slope, go around stone slab/obstruction left and up to top corner. From there obvious.)

Approach Valean he looks like a bad guy but transforms and speaks to you.
He will give you the quest, a 55 came with me and could not get it so I'm guessing you need to be up near 60.

You get the quest (I had gems and seal). Hand in quest. He gives you a box with two items. Open the box put items in your bag. Now you have to go to Dustwallow Marsh to a cave where there is a Dragon. Take a group of 5 people have a healer.
You fight the dragon till about 5% of health remains. Tell your group not to be idiots and use DOT's. The round item from the box will take over the dragon. If you have a pet Dismiss before starting you cannot be in control of the Dragon and another pet.

Once you have the Dragon to about 10% place the Seal on the ground by right clicking on it.

Then at about 5% of Dragon health stand near or under Dragon (healer handy now) and use the orb looking item by right clicking. This is how you take over the Dragon. Once in control you will get an extra bar (like pet bar) use the Flame option. You will be in control of the Dragon it's like Eyes of the Beast if you are a Hunter. Take the dragon to where you have placed the second item (It can be placed more than once near each other 5 Max). It does not seem to target the Seal to be fordged so try clicking on the seal and zoom the dragon eyes onto the seal, remember time is limited. Activate the Flame action on the Dragon Bar. Have one of your members nearby so tey can see if the seal becomes "Right clickable for looting". If so your done kill the dragon loot the seal (not from the dragon) and return to Valean.

Now remember it becomes a Loot item so anyone can take it!!

The Key to UBRS is not a key it's a Ring. Approach UBRS door and it will just open for you.

Seal drops from about any mob easy to get, you can only carry one.
Gems are from Bosses -

Quest can be done in a raid. Here is a summary of who drops what (in order of appearance):

Gemstone of Spirestone = Highlord Omokk
Gemstone of Smolderthorn = War Master Voone
Gemstone of Bloodaxe = Overlord Wyrmthalak
Unadorned Seal of Ascension = random drop from any mob in instance (or buy it off AH)
