From Blood and Relics Introduction:
Welcome to Blood and Relics, a supplement for the Modern system that brings gothic conspiracy to life in the modern world! This edition of Blood and Relics focuses on the Blood War between the Sang Real, servants of the Higher Power, and those who serve the Dark Powers—the butchering Caeder. The Blood War has been fought in secret since the dawn of the time, unnoticed by the bulk of humanity; its battles have unfolded even in the halls of the Vatican itself. It is a war fought not only over lost artifacts of power, but over knowledge and the soul itself. Blood and Relics provides a variety of new advanced classes for your Modern game: Relic Seekers and Grave Robbers who hunt ancient treasures in a personal bid for fortune and glory; dark Cultists who worship and serve fiendish masters, currying favor through offerings of blood; the Dark Warrior, who willingly invites fiends by the dozen into his body to increase his sinister power; to the Monitors, vigilant guardians of the most precious treasure of all, the Sang Real; and lastly the Believer, able to perform miracles of healing.
