Power in Uldaman

==Objectives==
Retrieve an Obsidian Power Source and bring it to Tabetha in Dustwallow Marsh.
*Obsidian Power Source
==Description==
Now that the demon has been removed, we must gain a power source. Unfortunately, the best power sources are usually the oldest and the hardest to get. It's neat how fate likes to take a bite out of you sometimes, isn't it?
So you're going to need to go to Uldaman and defeat the obsidian sentinel there. He's big, he's tough, and his power source packs a punch!
I wish you the best of luck, <name>. And if you don't get lucky then, well... it was nice knowing you.
==Rewards==
You will receive:
*3900 XP
==Progress==
Have you been to Uldaman, <name>? Did you defeat the obsidian sentinel?
==Completion==
You did it? Well done!
I was chatting with some of my colleagues and when your name came up they said, "You know that <name> sure works well under stress!"
But when I told them I sent you to Uldaman against the obsidian sentinel, they said I was crazy! They said, "Tabetha, you're crazy! There's no way <name> could take on that sentinel!"
And I said, "We'll see," and then they said "Yeah, we'll see..."
Well we sure showed them, didn't we!
==Notes==
Although this is a quest to kill a level 42 elite boss in Uldaman, it is in fact quite possible for a mage to solo around level 40. As a class quest, it may have been the designer's intention to teach mages some creative strategies. See the Obsidian Sentinel page for more information and strategies.
When you kill it, loot the quest item and return to Tabetha for the final stage in the quest chain.
