Approximately every hundred years, the Lord of Darkness, Dracula, is resurrected thanks to the dark desires of man. His armies of demons and undead threaten to consume the world in shadow, eradicating mankind from the face of the Earth. And every hundred years, it is the duty of the enchanted family of the Belmonts to defeat him in an endless cycle. Such is as it has been since Mathias Cronqvist betrayed Leon Belmont in 1094 and became the ultimate force of evil, Dracula Vlad Tepes, and such it will continue to be until the end of time or the inevitable cycle is broken.
Until then, darkness will always have a place in the world, and the forces of evil driving man to their own destruction will continue to summon the demon castle of Castlevania, and with it, the Dark Lord Dracula.
