The Dragon's Claw quest

not sure what i am doing wrong here, but i am unable to find the dragon claw key, i keep going back and forth between three different claws, where the quest helper sends me, and i cant find the key, the hint in the quest line says to search the street by the broken tower, lots of broken towers here, searched by them all, and i cant find a thing. any suggestions? quest broken maybe? or am i just not finding it?

ok, for those stuck on the quest, i finally got it figured out. the drop rate seems to be hard on these, but the claws should have a key in them, with green wisp like balls of light shooting around it, if you dont see it, move on to the next claw, after the 3 claws in the area are searched, if you find no key, switch realms, took me a few tries, but i finally got the keys, the dragon claws are indeed where the key is, its just a matter of the claw having a key in it, just a claw, no good, claw with key, your on your way to the next quest :-D
