I'm playing on Vox. Did the quest bit by bit over the last week. It still works! Took a long time to get Entalon/Gylton to spawn, and after clearing many mobs in the area, and waiting for probably 4-5 hours, each of them spawned. Gylton dropped the dragon scale. Same story for Gullerback/ Azdalin.
Some of the dialogue is missing for Lord Lyfyx of Burwood but the turn in for the 3rd dragon scale still works.
For the turn in to Tektite, on my wood elf bard, level 65, I managed to invis with the travel song to run behind him, then used sneak to con indifference. Turn in was a piece of cake. Make sure you give him the Carnelians single stacked, and in the same trade window at the same time, or you won't get the Tektite.
For the turn in of the 3 dragon scales, I hailed the barbarian lady in the FV allied settlement which supposedly spawned Sir Hobble. I say supposedly because I did it 6 or 7 times over the course of 3 days and I'm now convinced that its just a matter of commitment to waiting for a solid 4 hours before you'll see him spawn. For me, Hobble spawned WITH the squire, and GOOD NEWS is that he and Squire Fuzzmin no longer run through the zone. They walk the entire time AND they also no longer attack any creatures that they cross. It's as if they are invisible the entire time. This makes the turn in WAY easier...
I can confirm that Hobble and the Squire spawned near the LOC listed previously on this thread, just southwest of the tunnel entrance to the FV allied settlement. They march in a pattern, and if you set yourself up to track them in the middle of the zone, near the two white pillars (one cracked in half) you should have no trouble finding him on track when he spawns. I followed them for almost 2 hours just to see where they pathed, and the result was what looked like a sunburst or half-wagon-wheel spoked loop cycle, with the center being at the tunnel entrance to The Dreadlands.... Throughout their walking loop, they travel out to a handful of locations in the zone, then head straight back to the DL tunnel entrance, proceed a small distance down one of the branches of tunnel, then go back out and repeat.
For those who want specifics, the LOCs for the end of those wheel-spoke paths are as follows:
484.09, 5058.21, -55.96
380.08, 1498.67, 28.45
114, 1315.79, 26.16
1374.80, -171.83, 122.39
1066.38, 24.09, -125.97
The center of the wheel is at the DL cave entrance by the iksar statues.
