The Dragonborn Seal is a symbol of Leondel's royal power, and it is also a curse that entangles the bloodline. It can grant the power to control the weather and see into the future, but at the cost of devouring emotions and turning people into cold stone. Alvin, a young man from the border, has the last dragon blood flowing in his body. In order to protect the village, he was forced to step into the chess game of power, dealing with the decadent kingdom, the fanatical revolutionary army and the unfathomable church. When the former mentor Lord Reiner held high the torch of ideals but wanted to pave the way to the new world with blood, Alvin had to make a choice: embrace divine power and become a new "tyrant", or cut off the source of the curse and find a way for mortals to survive among the thorns?
