Wanted: The Exarch's Soul Gem

Within Auchindoun's Auchenai Crypts many unsavory experiments are undertaken in the pursuit of a greater understanding of the necromantic arts. Many are the spirits that are tortured or destroyed therein. I have a customer who is interested in the liberation of one of those spirits. I have been informed that this spirit is contained within a soul gem held by none other than Exarch Maladaar himself. Seek him out within the crypts with all due haste and return to me with the gem.
