Re: Scourge of the Silver Marches D&D 3.5
He didn't create it, he's a 14th level character. It's an artifact, actually it's part of the stone the main bad guys have that lets them control undead, he really had nothing to do with it being there. The amulet wants to rejoin the stone, so it forced the drow to the stone, and the main bad guys sent Gershalt to take control of her because they were too lazy to do it themselves.
