The stone is a corrupted piece of shadowstone, the same stone the Shadowstone Road in the dwarven homeland is made of and the obelisk monument in Silvergard, dedicated to the lives lost during the Shadow War. Chkikin also recalls a story about Lord Muzdum de Silvergard. During his quest to discover the fate of the original inhabitants of Silvergard, his brother had placed such a stone in Muzdum's pack without his knowledge to spy on him. It had been corrupted, however, and gave Muzdum and his companions visions of possible futures while also transforming the workers at a stone quarry near Vedlund into zombies. That particular stone was destroyed, or so the story goes.
