Rhapsody of Blood Core Rulebook

Every generation the blood moon rises, and the castle exalts a villain with its dark gifts. They shall command its legions, use its powers to twist reality, and seek the godlike power of the unholy grail.
Youre here to stop them. Your bloodlines have fought the castle since its first emergence, and that legacy has granted you endless tenacity, strange powers, or unbreakable faith. Together, you will root out the wards of the castle where they have infested the mundane world, slay the acolytes of the castles regent, steal their dark power for your own and banish the
regent and the castle with them.

But the castle is immortal, and the blood moon will rise again. As generations rise and fall, what tales of heroic action and gothic bloodshed will you tell?
