Hanyang, the capital of Joseon, appeared to be enjoying an era of great peace on the surface, but inside the palace, it was more fierce than any battlefield.

The frail King had been bedridden for many years and had yet to name a successor.

The King had Grand Princes born to the Queen and various concubines.

Though all were sons of the King, their mothers, maternal families, and supporting factions were all different.

The brothers smiled with etiquette and pretended to respect one another.

However, behind those smiles were hidden blades that could strike each other down at any moment.

The court ministers and powerful noble families sided with the princes according to their own interests, weaving a constant web of marriage, power, loyalty, and betrayal.

A single small rumor in the palace could save or kill a person, and a single choice could determine the rise or fall of a clan.

There was only one throne, and only one person could ascend to it.

The palace was the most magnificent yet most dangerous place in Joseon.

And so, the massive whirlpool of power surrounding the throne began to move quietly.
