The Veneficti belong to, and lead, The Circle of Red. This organization of wealthy merchants, vampires, and other supernatural beings seeks to corrupt creation and supplant God. To this end they subjugate demons, spirits, monsters and humans as they war with both God and those who would keep the world as it is. The Veneficti stand at the top of this order, an infernal sect of mages that believes no knowledge should be forbidden and strive to achieve a state that allows them to replace God himself, whose designs in the world they perceived as flawed and constructed to capture the weak. To this end, they deliberately summon demons from the Abyss to enslave them to their world and use their defilement to their own ends.
Their philosophy: by denying the power of the Judeo-Christian concept of right and wrong they can remove the control of Sin, by performing calculated acts from a Foundation of Sin they can attain complete control over body, mind and spirit. Deliberately sinning weakens the temptation that leads to spontaneous indulgence. Sinning repeatedly removes the power sin holds as a tainted pleasure or forbidden vice. Sin itself loses the power to gratify or instill guilt, and so becomes meaningless. Without sin, there is only choice and consequence, the fundamental essence of control. Absent any obligation to virtue or vice, Veneficti may work without the constraints of natural, or divine, order.
The Veneficti work their magic through the Subversions of the Divine Will, their pillars of: Abomination, the defilement of physical creation; Subversion, the defilement of knowledge; Diabolism, the defilement of faith; and Malediction, the defilement of truth. It is a common misconception that the Veneficti are slaves to demons. Those of this tradition scoff at such, for the truth is the other way around. The Veneficti summon, bind, command and banish demons as tools in their own bid for godhood and those that fall under the command of the slaves they would summon are considered weak and incompetent. For their part there are few beings demons hate more than the mages of this order and the power over them they can wield.
