The story takes place in Alberia, the kingdom where dragons live. All royal members in Alberia are able to shapeshift, where they can wield a dragon's power by forming a pact with a dragon to borrow their form in battle. One day, a strange occurrence begins to happen in this kingdom. The Sacred Shard protected by the capital starts to lose its power. In order to save his people, Euden, the Seventh Scion, who has not made a pact with a dragon, sets off on his Dragon Selection Trial.[5]
The Seventh Scion Euden, the youngest prince of the kingdom of Alberia, is told by his father, the king Aurelius, to seek out Midgardsomar, the Windwyrm, to forge a pact after the Sacred Shard of the kingdom darkens. Such a holy object can only be moved by a pactbearer, and to replace the kingdom's Shard, he must forge the pact. He goes to Midgardsomar's home, the Mistholt with his sister Zethia and their friend, the faerie Notte.
