The 5th century. The world is undergoing change and stands on the brink of one of its greatest conflicts ever: Christianity has set out to conquer the world and confronts the old pagan religions. In the shadow of these events, druids and monks engage in an unrelenting war. While the Bretons settle the rocky coast of southern Brittany, Gwenchlan, the last druid of this region, and Taran, his apprentice, try to free their people from the clutches of fanatical opponents. Morrigan, a goddess from the otherworld, assists them in this difficult challenge. Hidden among the remnants of ancient Celtic customs lies a dark and ever-growing threat. A dense and thrilling thriller, illustrated by Lamontagne in beautiful, detailed images that transport us to the Middle Ages.
