Located on the banks of a river that flows near the Haunted Forest lies a seemingly ordinary village that hides a dark secret. The village is a part of the Vampire Castle, which is shrouded in mystery and surrounded by the supernatural. The Vampire Castle is the tragic legacy of a Vampire King who lost his child, and his grief and sorrow transformed him into a monster who took over the village and its inhabitants.
Despite the village's dark history, the locals live their lives peacefully, although there is one monthly event that reveals the dark truth. Once a month, the villagers voluntarily offer some of their blood to the Vampire King to appease him, although it is no longer necessary. Fortunately, the villagers have developed immunity to vampire venom, and they are protected from the King's wrath.
Within the village borders, vampires are free to roam at night, but they must obey the rules set by the King. The King is strict, and his rules are enforced without mercy. If a vampire kills a villager, they will receive the same fate - a wooden stake through the heart. The citizens of the village fear the King, but they understand that it is a small price to pay for their safety.
The Vampire Castle and its village remain shrouded in mystery, and few outsiders venture there. Those who do know of its existence must tread carefully, for the King's wrath knows no bounds.
