SI:7 Headquarters. Stormwind.

A you clerk sits nervously outside the door of Master Shaw's office wondering why he has been called from his normal duties. The door opens, a shady one-eyed goblin sticks his head out the door, looks at the clerk and with a wicked grin
"Ere you, boss wants a word"
The clerk even more nervous now stands up and stumbles into the office and stands in front of the desk fidgetting.
"Sit down man, why do you look so nervous?'
"Errr y-y-you called me to your office sir."
Master shaw looks at him absentmindedly and then looks down at the papers on his desk, after a few minutes of sorting through the piles of papers he finds the bundle he was looking for.
"Ah yes that was it. I have your first assignment, you've been here for a few months now and i think its about time you see some action."
"Action sir" the clerks says, gulping loudly and looking more nervous than ever
"Dont look so scared man, we have received a few reposts about something that idiot explorer Bran has gotten himself into and the king has asked me to intervene if i can. It seems that the dwarf has unlocked what appears to be a giant prison in search of treasure and its been decided that a team is needed to go in and secure the place. thats where you come in boy."
"Really sir?"
"Yes you see one of Bran's bodyguards a particulary stoic Paladin called Renever was involved in the opening of the place and that gives me an idea about who i can send into this Ulduar place or whatever its called. Renever is part of a group known as Acta Sanctorum and they did a pretty good job of bringing down the flying fortress Naxxramas for us a few years back. I think we can pull a few strings and get this group to do our dirty work for us."
Shaw hands the clerk the bundle of papers, which the clerk sees are files on a number of prominent adventurers from same group. After a few seconds of looking at names he has heard in stories across the land he looks back at his master who has a slight smile on his face.
"I want you to find these people for me and get them to Northrend and Bran. There is a problem, since the fall of Naxxramas most of these people have retreated from the public eye and we have been unable to locate most of them, well all of them except one. There is a blacksmith at Azure Watch outside Exodar, who fits the description of a formidable warrior named Zahriel, if it is him then he is the key to getting this group together, he knows where everyone is. And that is where you start."
"Exodar? thats on the other side of the world, how will i get there?"
"By boat of course, do i have to spell it out for you, i have had a horse, supplies and passage set aside for you, you can set off within the hour. Oh and don't fail me. Dismissed."
