The Silvermoon werewolf capital is under siege by the army of cold-blooded vampires, yet Elias, the first heir, is still regarded by everyone as a "worthless good-for-nothing without a werewolf." He lives a life of debauchery in the royal tavern, secretly suppressing the Black Moon Blood Flame with the Eclipse Ring, guarding a secret from seven years ago. The old werewolf king Aldric retreats step by step to protect his throne, and his close advisor Kael seizes the opportunity to push the princess into the enemy camp. A moment of carelessness, with a spilled wine glass, reveals the cracks in the prince's facade.
