to get to vendor, vi'el. once in winterspring go south from everlook until you hit darkwhisper gorge (the area where the snow turns to dirt and there are elite demon guards). as you enter, do not attempt to go through the guards. i did this and aggroed, though it is easy to run out and lose aggro. it is FAR easier just to stick to the right, and ride the mtns past the guards(actually be in the mtns, going over the hills, not on the ground next to the mtns, though this should probably work too, but i think it is better to climb the mtn a bit), eventually you will get to the spot where you can go up to the cave. this is not too far past the guards, near the second pillar on the right. this is way easier than trying not to aggro as you walk through the guards. also, you will bypass the guard that is at the bottom of the hill where the road going up to the cave is, because you will hit the road about in the middle rather than at the bottom where he walks. at that point stick to the left of the road so you can pass the guard at the cave... do it as his back is turned. my ride here has produced no felcloth, but i'm gonna wait it out a bit and see if some shows up. good luck
