This section provides a deep dive into the Kytons 5e ecosystem—a unique class of fiends distinct from the warring factions of the Abyss and the standard hierarchies of the Nine Hells. While many DMs are familiar with the common Chain Devil, the Kyton species represents a far more complex society of industrial horror, obsessed with the interplay between metal, flesh, and the spiritual perfection of pain.
Kytons seek to transcend the physical form through torture and the application of sacred chains. They serve not just as wardens, but as dark philosophers of the Nine Hells. Each subtype of Kyton is optimized for a specific role in this “biology of agony,” making them cunning and dangerous enemies for any high-level campaign.

The Labyrinth of Chains: The Kytons’ Domain
Deep within Minauros, the third layer of the Nine Hells, lies the Kytons’ true seat of power. Beneath the acidic marshes of the polluted swamp, the Kytons have carved out a massive, three-dimensional labyrinth. This realm is a living nightmare of shifting architecture and gravity-defying design.
Architecture of Agony
The labyrinth is not merely a structure; it is a living entity tethered to the collective will of the Kyton species. It consists of:
- Shifting Chains: The primary building material. These chains rearrange themselves constantly, closing off paths and creating vertical traps that respond to the desires and fears of those within.
- The Gravity Well: The labyrinth distorts spatial orientation, making it impossible to navigate without Kyton guides.
- Functional Chambers: The maze contains thousands of specialized rooms, including Alchemical Workshops for chain-smithing, Shrines for the worship of pain, and Arenas where Kytons test their martial limits.
Strategic Importance: The Triple Gates
The Labyrinth holds a secret that even the Archdevils of the Nine Hells covet: three hidden gates leading to the Abyss, Gehenna, and Tartarus.
Because the labyrinth’s composition is so volatile, only a few selected Kytons know the location of these portals. Devils who trespass in search of these gates often find themselves lost—eventually becoming fodder and a source of amusement for the Kytons, who show no mercy regardless of the intruder’s rank.
For the Kytons, the labyrinth is the ultimate expression of their philosophy: Pain is the path to perfection.
