This is a world where only strength is decisive. A world where the weak are used, humiliated or kept in slavery, and the strong are forgiven everything. Here, only those who can vouch for their words with steel and blood are considered. Well, true power is recognized only for those who managed to ignite the Spark of their own Soul to the state of a hot flame. These are called Owners. They are the military elite of the empire, trump cards in any dirty game and the decisive argument in every dispute. Great warriors and talented artisans. Those who every child dreams of being from an early age. Dunmar, a cursed boy, intends to become one of the Owners, in whose body, at the behest of the Devil himself, the tormented soul of an ancient sinner has settled. To awaken his Spark, Dunmaru will have to train side by side with arrogant aristocrats, in the very thick of their intrigues and machinations. Will the knowledge and experience of a thousand-year-old soul, which has gone through countless battles, help a young boy not to drown in the whirlpool of other people's plans?
