A while ago, I had an incident with the Shadowforge Dwarves. They brought me to Angor Fortress to study two types of strange stones from Uldaman. I discovered that the stones were sustained, stable power sources if treated correctly. It's amazing the things one can find in that old dig site!
Anyway, after I told them the secret of the stones they kicked me out of Angor Fortress and began digging for more in Uldaman.
I want those stones for myself! Bring me both types and I'll pay you plenty!
That's great, you found some! Thanks a lot, <name>. You're the most dependable <race> I've met!
I can't wait to try these on some devices I've been tinkering with. I bet that, under the right circumstances, devices powered with these stones will keep going, and going, and going...
