Chain devil

Chain devils, or kytons, were a type of devil.

Description
Kytons were tall humanoids that wore chains as opposed to regular apparel. The chains wrapped tightly around the kytons like a shroud, rattling as they moved and slithering around their bodies as if they were alive. The areas where a kyton's eyes, ears, nose and hair would be were also wrapped in chains, with the only visible areas being their throats, grinning mouths and the occasional glimpse of a single, glinting eye.

The spiked shackles were covered in barbs and iron scraps that had been welded on, with each length ending in a hook, blade or weighty ball. Their normal weight combined with that of their chains made kytons weigh about 300 lbs (140 kg). It was often difficult to tell a kyton from a regular human draped in chains, although they were frequently mistaken for undead as they matched the traditional idea of a shackled spirit.

Personality
Sadistic and cruel, chain devils gained great pleasure from inflicting pain. Their love of torture made them easy to work with for any entity willing to let them indulge in their brutality. Kytons savored the terror of their prey so greatly that they carefully deciphered the best way to inspire dread in their victims through an enigmatic methodology. Whether through a foreboding direct chase, fleeting between the shadows, or stalking their prey for hours, kytons hunted with whatever method induced the most terror in their targets.

Abilities
Chain devils animated the chains on their body and swung them around to rend and restrain their targets. While kytons normally could move only their own chains, a ritual known as the Gift of Chains, allowed them to manipulate chains not attached to their bodies. Up to four chains near the kyton would be animated, causing them to rattle, dance, extend by or gain jagged spikes. The chains also increased a kyton's mobility, letting them freely move and climb along the metal ropes.

Chains within the possession of others could be mentally restrained to prevent the kyton from taking control, and if more than one kyton tried to control the same chain, it would not move until one kyton established dominance. Animated chains could restrict and lash out at opponents on their own, but could still be broken and would revert to normal after sustaining enough damage or if the chain devil that created them was incapacitated.

Kytons also had the ability to assume the faces of deceased individuals known by those that saw them, whether they be loved ones or hated foes. Although all one could see was the lower half of their faces, it was often enough for the victim to recreate the intended visage. Through this unnerving ability, chain devils temporarily caused their prey to run in terror or stand still in shock.

Kytons constantly regenerated from any injury, never bleeding and regenerating lost limbs when not simply reattaching them. They could not be harmed by the cold nor weakly enchanted weapons. Only weapons made of silver or those with stronger enchantments could harm them, but blessed weapons were capable of slowing their regenerative abilities.

Combat
After chain devils had finished stalking their foes they attempted to capture them alive in order to continue torturing them later. When seriously fighting, they danced around the battlefield wildly swinging their weapons and nimbly dodging any attacks made against them. They only used the Gift of Chains if sorely pressed, or if they believed doing so would strike terror in their targets. When met with blessed weapons, kytons immediately retreated.

Society
Chain devils were the jailers of the Nine Hells.
