Here we go again.
I've already found 2 posts about this.
But first one required you to get feared from WG.
The other one seemed to miss the most epic part.
So i decide to continue those threads.
The only thing you will need is a flying mount and the ability to fly in Northrend.
1.

This screenie is taken just above the long stairs that is the Entrance to Icecrown Citadel. Whil stand on the stairs you need to fly up abit to see this.
2.

Once your up there it should look something like this.
Just fly where the arrow points.
3.

Once you've done that it should be like this.
4.

Press "X" (if its bounded to Sit) Otherwise just fly down the hole.
Then should be here. And as you can see theres another arrow!
Follow it! (Heres where the other thread didn't show)
5.

When you get to this place you will be stuck! (WTF? GOOD GUIDE NOOB)
Yes indeed. Though the devs failed pretty hard on this invisible wall. Just fly up and over it.
6.

Like this! Then fly down or press "X" to get down.
7.

And finally. In the hole! Easy huh?
When you go down the hole. Its not to hard to get where you want for example you will see WG to the right if your in to that kind of stuff.
TRYED THIS SATURDAY 15TH AUGUST! And it worked.
Sorry for spell misstakes and bad english. And my bad graphic card.
I hope you like it though its a repost. But this one is better. -> IMO <-
I was writing this thread when

Was added. But it pretty much the same but this one seem to be alot more effortless.
