This is a fantasy epic that combines Eastern and Western characteristics. The core revolves around blood, curses and rules. The Edwin Dragonborn Dynasty respects dragon blood, and the Holy Dragon Church has monopolized magic for thousands of years; those who cannot awaken their elemental talents on the Day of Divine Grace are "embersless" and will be deprived of all identities and rights. The third prince, Kailuo Edwin, was originally the proud son of heaven, but during the awakening ceremony, he was judged by the Holy Dragon Crystal to have no elemental response, and was exiled to the north by his biological father in public. The hard labor in the mining town and the screams of the elf slaves are intertwined with the black dragon crystal deep in the mine veins. A bloodline scam that has been hidden for thousands of years is being uncovered by this "waste prince" himself.
