Under the complicated pattern of hundreds of kingdoms in Noah's continent, the human kingdom relied on the church system left by King Solomon to maintain a fragile order. The Kingdom of Anglia was blessed with "golden blood" due to the work of its ancestor King Arthur, and it enjoyed great honors but also shouldered heavy responsibilities. Princess Elinor, a girl who is unable to awaken traditional magic but is well-read and independent-minded. During a routine church inspection, she unexpectedly showed the legendary "blue blood" - a supreme blood form that far exceeds ordinary people's knowledge and contains ancient power.
Her awakening shocked the royal family and the church, and also attracted the prying eyes lurking in the dark. For the sake of the glory of the bloodline, the survival of the kingdom, or a deeper plan, Church Bishop Helios, in the name of "hardening", urged Elinor to join the "Northern Expedition" aimed at regaining the lost territory in the north. Elinor resolutely embarked on a journey to the Holy City of the Church.
However, this road to "glory" is full of thorns. The snobbishness of the nobles on the same train, the unpredictable intentions of the bishop, the strange choice of route, and the deadly threat of the ancient enemy "the dark species" came one after another. The accompanying church whisperers and the secretly guarding royal shadow guards seemed to indicate that this trip was by no means a simple trial. Elinor must rely on her own wisdom and newly awakened power to survive the game of the various forces and the flames of war in the north, and gradually uncover the ultimate secrets about her own bloodline, the truth about the church, and the annihilated history of the Demon God Era.
This is a Western fantasy epic about bloodline glory and personal choices, ancient contracts and imperial ambitions.
