From DrivethruRPG:
Welcome to the world of THE VAMPIRE • ALONE IN THE DARKNESS, a game for Solo or Group Play. In this game, each player takes the role of someone who, after their death, is possessed by a powerful shadow demon who brings them back to life, transforming them into a mythical Vampire and granting them incredible powers of darkness.
But the cost of this transformation is high: the demon that comes to inhabit your body cries out for the blood of mortals and, at any sign of weakness, it will take control of your actions and will undoubtedly carry out its will without thinking about the consequences, being able to completely destroy your life in the process! You’ll try hard to resist the creature’s dominion and - who knows? - even overcome it and keep it silenced for decades or maybe centuries.
