The Dreamers of the Black Sun are a left-Handed Legacy of the Mastigos that are founders and leaders of the Mexican Black Sun cult, that draws its traditions from the days of the Aztecs. Among the Aztecs, the Dreamers were a death cult without the power to match their rivals, constantly at risk of complete destruction. Even in modern nights, their numbers are too few and their practice too dangerous to allow functional long-term organization. Turnover is frequent in the cult, and on average, the Dreamers lose members faster than they gain them.
Members of the Black Sun Cult believe that the mortal world is warped and corrupt by design—a misbegotten, chaos-laced creation built by hubristic, degenerate gods. In these mages' eyes, perversion is implicit in the design of every earthly object and inhabitant. A paradise once existed, they argue, and it was torn apart to provide the base material for the ruinous human world. This paradise is identified with Tamoanchan, the mythical Aztec world of Itzpapalotl. The only survivors of its destruction are the demonic Tzitzimime, distorted spirits of vengeance bent on the annihilation of Earth. Trapped in the sky and hidden by the sun, they await the day of unending eclipse when they will drop to Earth and visit the righteous fury of their forgotten world on all of humanity. The Dreamers often communicate with spirits they identify as Tzitzimime, hearing their whispers from the rippling chaos of Pandemonium. To empower the agents of Tamoanchan and better receive their guidance (or even encourage their manifestation in the mortal world), the mages of the Black Sun Cult work to provide sacrifice on a grand scale, sabotaging structures and transport systems in an effort to murder dozens or hundreds of souls at once. These sacrifices are ritually prepared and carried out so as to channel energy to the Tzitzimime, providing them with the strength to slip their bonds and come to Earth. Eventually, the Dreamers hope, the energy gathered will be sufficient to bring about the day of unending eclipse and end the pain of life.
They primary utilize the Mind Arcanum in their twisted rituals that make use of the raw power of fear, ritually occluding conscious thought by immersing the practitioner in base terror and opening a conduit for the energies of Pandemonium to pass through. They call this "opening the bone passage," a practice that puts considerable physical strain on the mage. To help stimulate the effect, Dreamers often subject themselves to threatening circumstances with little or no guarantee of survival, trusting their own power to preserve them. Many actually remain at the site of a planned sacrifice (for instance, sitting as a passenger in an airplane that has been sabotaged), allowing themselves to participate in the tragedy and risk becoming its victims. The heightening of fear that precedes the event often provides them with enough power to survive once it begins—but not always.
