The Troll Hall Chronicles
Soul Shard of Vyrellis
The Soul Shards of Vyrellis are magical objects containing the essence of Vyrellis, a woman who has been trapped within the Pyramid of Shadows in the form of an obsidian sphere for untold aeons. They bind her essence to the prison and without them, she will never be free of it.
The shards are:
*The Moonstone, which was retrieved from the chambers of Grarash, the marsh mystic
*The Garnet, which was retrieved from the Chapel of Celestia
*The Amethyst, which has not yet been located
