Urheld Darkstone, despite being an alchemist of great skill, was thought insane by his contemporaries and, hence, did not share his research. Instead he etched it onto tablets. He hid one of these, the Darkstone Tablet, which contains old alchemical recipes, in the Hall of Fortune in the Blackrock Spire. Vivian Lagrave now searchs this tablet for the Royal Apothecary Society.
