Black Faiths

The Black Faiths is a term referring to in fact a single, yet highly decentralized and loosely connected religion. It is based on the worship of demons and the dark powers of the void. Its members are often nihilistic and apocalyptic, believing that the eradication of demonkind's enemies will grant them favor with their dark gods, and in turn mastery over the void. They are organized by various covens and cults, which are known as Chapels to them.
Many of these cults were started by warlocks and revenants, who claim to have heard whispers of the true gods. In reality, it was likely they were contacted by demons. 
The sadism of the Black Faiths is apparent to it's enemies, but some in moments of weakness find solace in its promises. The disenfranchised and peasantry are drawn to its promises of brotherhood, wealth, and even eternal life. Escaped criminals and slaves, or those with severe sentences, will sometimes find refuge in these Chapels. In other situations, people may be forcefully conscripted into the Chapel's ranks, lest face death, or a fate worst. Those wounded and left for dead by bandits or animals will sometimes be taken in and cared for by a coven of the Black Faith, who will in turn convert them, mutually or forcefully. During the Black Age, the Black Faiths reached their greatest heights. Multiple conditions fueled the growth of cults to massive sizes, some forming their own armies and assaulting entire kingdoms. However, the destruction and havoc these cults wrought, as well as victories against them, eventually diminished their popularity and power, until they became all but secretive covens.
The practices of the Black Faiths vary greatly from region to region, and sometimes they draw influence from local heathen beliefs, which have led to the heavy persecution of pagans as well. The Triune considers the doctrine of the Black Faith to be dangerously tempting and addictive, and heavily brainwashing. Most who follow these cults eventually become sadistic and insane themselves from their exposure to void forces, even if they had entered it skeptical. It is this dangerous ability to turn once good people into sick and ghoulish fiends which has made them a dangerous enemy to the Curators and the triune. 
The Black Faiths are seen as cursed by most and interacting or witnessing their dark practices is believed to be a bad omen.

Most religious groups which follow the Black Faiths are often warlock covens or some sort of nihilistic, demon-worshiping cult.
