Among the seven realms ruled by a single crown, twins were born to the queen under a prophecy that said: "One will rule all the realms… and the other will be banished to rule forgotten kingdoms." Marsius was the calm of power and the language of the throne, while Cassian was the unquenchable spark of rebellion. The twins grew up with one heart… until she appeared. A woman of the lineage of the Ladies of Balance, without whom the reign of a true king would be incomplete. She was not merely a witness to the heirs' struggle… but became the center of the conflict, the spark that altered their destinies. Her love… her strength… and her place in the prophecy redrawn the lines of fate between the brothers. The conflict ignited, not only over the throne, but also over her—the royal prize that would accompany the next ruler. And today… one of them will sit on the throne of the seven realms with her, and the other will be banished to build his kingdom in a land that does not know his name. And yet… a brotherly love remains between them, a love that neither the prophecy—nor she—could extinguish. Welcome to the world of Marsius and Cassian… a world that is merciless and chooses only the strongest.
