Keystone Quandary

In my time collecting various sundries for sale back in the Empire, I've come across stories both unintelligible and outrageous. Take your precious gromril mine for instance! A more unpalatable bit of codswaddle I've never heard! Besides, where's the profit? You'll lose half your man power just getting past those filthy Orcs, and then you won't be able to cart anything home! The Helm of Thargrund however, that's another tale entirely. If I remember right, it's about a master crafted helm kept within a hidden keystone in yonder Thargrund. Be weary of Thargrund's inhabitants! They were once Dwarfs but fell victim to a creature of legend: Naxael the Soul-Feaster. It is told she is a broodling of Azorgaron and possesses power of unspeakable evil. The souls of Thargrund eternally await for Naxael to return and collect them. Don't go rushing off, you'll need the four rune stones to get inside! They could be anywhere in this accursed place, so keep your eyes open.

The Rune Stones of Thargrund have been scattered throughout the area. Search the Thunder Mountain battlefield, the pass to Death Peak, Whoosha's Boyz, and the path toward Peak's Edge for them. Once you have collected them all, venture to Thargrund in Sparkstone Ridge and place them into the keystone atop its tower.
