Alex Adams never considered herself a hero, much less the hero of the magical war she found herself a part of. She was only a mage because worlds never meant to interact were doing so. Merlin and Morgana trained her to control her powers, but nothing had prepared her for Arthur. Yet Alex has a promise to keep even if she didn't feel ready. Aiden's life was hanging in the balance and their best chance was in an artifact created by another Iron Soul and lost centuries ago. Now the newest generation of mages must leave Ravenslake behind and find the Iron Chalice to have any hope of saving their friend. Years after losing Arto to Medraut's betrayal Merlin and Morgana discover a young man with familiar talents. He is the key to answering a question from their past and revealing their futures. However, the Old One Badb is seeking the power of Cathanáil. It had taken all their power and the Iron Soul to end the last war, but now a new battle is looming on the horizon.
