The artifact bears markings that indicate its origins as being created by the Thunderlord clan orcs. These orcs used to live at Thunderlord Stronghold before they were changed into fel orcs.
For a time the Bladespire ogres inhabited the stronghold until recently when the Horde pushed them out.
You've heard of other artifacts that were lost. A drum, an arrow and a tablet come to mind as objects that you know are being sought after.
Find them in Bladespire Hold and return them to Rokgar Bloodgrip.
Details
The Arrow can be found at the top of a stone ramp which leads to the top of the stone structure with the dragon carcass within which 4-5 ogres tned to gather around. The Ogre Glumdor can be followed to find this ramp, as he walks up it himself during his patrol route. (location 41.5,52.7).
The Drum is in a small building on the southern side of the Hold (location 40.2,58.3).
The Tablet is in a hut on the north side of the Hold (location 41.2,46.5).
After you loot each object, it will despawn temporarily. It will return about 30-45 seconds. (Note: These items are not despawning on the current patch.)
The Drum and Tablet artifacts are guarded by Bladefist champions within their huts.
