Belzenlok's Cultists
Cabalists are uniformly fanatical, tormented into zealotry by pain, greed, and the distinctive power of their dementia magic. From the Cabal's beginning, spellcasters known as dementists have manipulated the very stuff of nightmares, reshaping reality and creating items and creatures from the parallel realm of "dementia space." Though it has been greatly changed by centuries of hardship, dementia magic remains a powerful asset of the Cabal, and cabalists value prowess with such magic above everything except the favor of Belzenlok.
Cultists, Initiates, and Priests
Most members of the Cabal serve it in a religious capacity. Cells of Cabal cultists are found throughout the world, worshiping Belzenlok in secret. Once inducted into the Cabal more formally, cultists shave their heads and become initiates, assisting priests in their dark rites. As Cabal priests rise through the ranks, they dress more ornately, often wearing headgear or high collars that set them apart from initiates. Most Cabal clerics are dementists, and carry with them implements of sacrifice and veneration. But a few are more martial in nature, wielding heavy blades and viewing combat as the most active form of sacrifice to Belzenlok.
Grimnants
Cabal knights are all members of an order called the Grimnant. The armor they wear has been melted down from scavenged or stolen pieces and forged anew, painted in a black lacquer and with its edges honed. Often, the armor is molded to mirror aspects of the demon Belzenlok, a form of idol worship that Grimnant knights believe gains them power and favor.
Grimnants are brutal combatants who arrive after the Cabal's infiltration has weakened a target. Most have some minor knowledge of dementia magic or carry trinkets that give them the ability to wield dark magic in battle, but they're not generally known as spellcasters. Appearing stoic from afar, most Grimnant knights experience a bloodlust in battle and enjoy going in close for the kill.
Infiltrators and Assassins
In its cells throughout the world, the Cabal has need for more than prayer. Whether striking from the shadows or venturing out in full regalia to spread open terror, Belzenlok's infiltrators and assassins emphasize what many fear: that the Cabal is already everywhere.
Belzenlok's cultists can gain the Demonic Vigor trait. Favored cultists or cult leaders can also have the Unholy Tether trait.
