The Shadowstone

The Shadowstone was an immensely powerful artifact that made Kadaena almost invincible. Many of the Maia and Vala feared this item. This item had the ability to devour souls and Kadaena wore this proudly on her necklace. Luckily Kadaena was killed by Utha and the Shadowstone was lost, unfortunately Ondoval eventually recovered this item.
