Take the reward voucher to Bena Winterhoof in Thunder Bluff.
I shall focus my energies on these discs; they will reveal their true workings to me in due time.
As for you [player], I will now reward you for your diligence in bringing this to my attention. Take this voucher to Bena Winterhoof, the alchemy trainer for Thunder Bluff. She will give you a special item I believe you will find appealing, and she will supply you with a choice of potions from my personal stock.
Return to me soon, as I sense there is much more at hand for us to do regarding this find.
