Noxenthar

Noxenthar are not born but called. The ritual to bind one is old and austere: a priest carves an aperture of obsidian, murmurs the Name of Unlight, and offers a handful of frozen breath and a grave's hush. In return the Noxenthar becomes guardian, tied to the shrine or vault until its charges are fulfilled or until sunlight bleaches its bindings. Temples of the funerary cult known as the Keepers of Quiet still use them in remote crypts, and several crypt-robbers' broadsides preserve warnings about the ‘silence that eats hands.’ Scholars such as Master Veldin of Idris have argued Noxenthar are fragments of a colder plane — a bruise of night that learned intent from ritual. They haunt places where shadow is plentiful: vault corridors, dim catacombs, candlelit mausolea. Legends tell of a Noxenthar turned mad when its ward was desecrated; it abandoned its post to wander cities, slipping into the shadows of alleyways and preying on unsuspecting sentries. Priests who bind them carefully mark the tombstone; the unmarked places are the ones thieves come to regret.

A Noxenthar appears as a roughly humanoid silhouette of matte black that seems to be made of smoke condensed into oil. Its edges ripple like fabric in a draft, but the center is thick and velvety as night. Where talons form, the darkness sharpens into finger-like icicles: translucent black-blue claws that steam cold breath. Its 'face' is a field of thinner shadow with no features except two pinpricks of darker void where eyes might be; these eye-like voids suck in light slightly, leaving nearby surfaces rimed with frost. Around its torso and shoulders dark filaments coil and slip into cracks or the gap between plate and skin, as if the creature can flatten and flood narrow seams. Scale reference: when standing beside a human, it is about the same height but appears maddeningly thin and capable of flattening to the width of a dagger. Textures should show dense crosshatched black for core areas, lighter hatching for drifting edges, and stippled white highlights to suggest frosted cold on edges.
