In a different world than this; a world with curses and legends, ghosts and dragons, a war consumes the land. Two kingdoms who have not known peace for thousands of years fight for the upper hand. The kingdom of Psychi controls the West. The people there are soft from the easy lifestyle the land provides. They are kind, but their kindness holds deception. Kokato controls the East. The people there are rough around the edges, hardened by the never-ending fire and harsh conditions. This makes them tough, calculating, and controlling. Kokato holds a secret within its palace walls, an assassin. Once marked there is no escaping the edge of their blade nor the drip of poison that may sneak past one's lips. During a tender truce between the two kingdoms this assassin is given a mission that'll destroy that peace: kill the King of Psychi. And she never fails to complete her mission.
