Drywhisker Gorge
From WoWWiki
A gorge cutting through the mountains of eastern Arathi Highlands, to the North East of Hammerfall. At the end of the gorge lies a cave, which is the only known source of Bloodstone ore. It's currently inhabited by Kobolds. Deep within the cave, a mysterious stone shard can be found, in which a piece of essence of princess Myzrael was trapped. Some players feel the location of the case is to the south and east of Hammerfall. You run into kobolds to the south and east, but the cave is east and slightly north of Hammerfall. Obtaining the motes, as per the quest, can be solo'd but taking them to the shard inside the cave really requires a group. Kobolds are levels 35, 36, 37, 38.
Cave entrance can be found at 82,37 Arathi Highlands. Appears to be due east of Hammerfall on the map.
