Vampires. From the Family Chronicle of the Counts Dracula-Kardi

An ancient abandoned castle stands amidst the majestic Carpathian mountains. At its foot lies the Valley of Witches, where men go missing with every full moon. A lake covered with dead, yet beautiful water lilies. It is said that in the moonlight, they take the form of enchanting maidens, whose beauty is deceptive and treacherous.
The heirs of Count Dracula begin their bloody hunt once again. Will you be able to hide from the children of the night and save your soul?
