Cephalyx

[The cephalyx are the Iron Kingdoms take on the psychic slaver trope that is so common in post D&D fantasy. And I loved them when I first discovered them. I thought they were so stylish with the black leather and blank faces and floating six inches off the ground, in ways that in retrospect were gender envy for a teenager who know that "he" didn't like "his" body but wasn't sure what would be better. Plus they lobotomize people and fit them with giant diving helmets and industrial equipment (Bioshock you hack!), which is a fun hook. The trick to this conversion was making them feel mechanically distinct from all the other psychic slaver monsters. The mutilating rend is borrowed from their 5e incarnation, but that version also has a weaker version of the mind flayer's mind blast. In the interests of giving them Pathfinder flavor, I tied them to the kytons/velstracs.]
Cephalyx CR 6 LE Monstrous Humanoid This humanoid figure is shrouded from head to toe in black leather. Its head has an elongated cranium, and its face mask is studded in eye holes and ports. Four long mechanical arms extend from its back, each tipped with sinister-looking blades. The creature floats slightly above the ground.
The cephalyx are more a subculture than a species—although they are biologically human, they have transformed themselves through a combination of occult power and surgery into something greater. They seek to expand their numbers, and do so through raiding, capturing and enslaving other humanoids. Each of their victims is scoured for whatever particular combination of traits the cephalyx believe mark a candidate for ascension. Those that fail these tests, and that is the majority of their captives, are surgically altered instead into drudges, incredibly tough and nearly mindless slaves that serve the cephalyx as physical labor and defense.
A cephalyx usually battles from the back lines, commanding an army of drudges to soften up opponents while they support with psychic magic and projectiles flung by telekinesis. They close to melee against surrounded or isolated opponents and tear them apart with their mechanical limbs. If a cephalyx can latch all four of its limbs into a single target at once, it can lobotomize them, tear their tendons or otherwise render them a mutilated wreck but still alive—perfect to be hauled off by drudges for analysis and further surgical alterations. Cephalyxes are not cowardly, but value their lives more highly than those of their drudges, and will not hesitate to sacrifice their minions in order to make an escape.
The first cephalyxes were devotees of the kyton demagogue Vevelor. They view their butchering art as a form of transcendence—they freed themselves from the confines of mortality and morality by becoming occult cyborgs, and free their drudges from the burdens of sapience and self-determination. Other cephalyx collectives may venerate different demagogues as their primary patron, but all view kytons as ideals and seek to emulate and ally with them. Cephalyxes do not die of old age, and some are hundreds of years old, but once they have completed some specific goal—known among them as The Great Work—they kill themselves in order for their souls to pass into the Plane of Shadow and take what they see as their rightful place among the kytons.
Cephalyxes prefer to communicate telepathically, and many of them have missing jaws, tongues or other appendages that make speech difficult.
