In the kingdom of the House of Mordasini, a future king is waiting for the day to come when his father will die. While there's nothing to suggest that King Maynard will be leaving this world anytime soon, his oldest son, Aldin, increasingly desires to be the one on the throne. With the darkness that has been residing in his soul since he was a child, ideas begin to flow inside of Aldin's mind. All around him, there are things happening that go against his idea of how the realm should be run. In particular, the realization that his father has granted permission to his brother, Prince Iztal, to wed is something that adds to Aldin's hatred for his brother - a hatred that has grown into an intense obsession.
While brothers continue to share their volatile relationship, their sister continues to experience signs that a beast will soon arrive in the realm, eager to cause destruction. Everyone thinks they are ready for the beast's return, but are they?
