Power Stones

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!
