Start at 78,50, head up the path (1). Follow it up to about 80, 40 then head right (2). You're heading along that ridge you can see stretching right in (3). In (4) you can look down and see some nice buildings. Don't get sidetracked, head kind of up and right to 82,58 (5). There's a little slope here that you should go round to the left of, not right, or you'll slip to the valley floor.
At 81,65, which is kind of straight on and left a bit (6), you can just see Searing Gorge in the distance. Head down veering left a little bit, carefully, as there are some steep falls around. head for 88,0 (7) which is a safe place to drop down from.
There's quite a big area to roam around in here (9), and you can drop down either in the Badlands (anywhere in the north really), Loch Modan (valley of kings), or Searing Gorge.
Don't ride down the spine between Searing Gorge and Badlands without due care and attention, or you'll fall in this hole (10) and have to hearthstone it out!
If you head west as far as you can, you'll find a place to drop down into Searing Gorge. Keep going west and stay as high up as you can to the north. Eventually you'll come across a small flat snowy area with some machines in it. It's deserted, so don't worry. Drop down into it and out the western exit. Follow the path down and you'll reach Thorium Point shortly. I didn't pull any mobs on the way down, but might have been lucky!
Once there, the flight master is kind of through the camp to the left a bit.
