Princess Diana is raised amid the deep love of her three protective brothers in the frozen realm of Frostmark.

Instead of tearing her apart, the mythical sovereign kneels before Diana, acknowledging her sacred bloodline and crowning her queen of the molten depths. As the brothers uncover the deceptive scheme and freeze in eternal winter, they march to the abyss begging for pardon, only to face Diana's blazing draconic wrath.
