Veshul

Veshul are born where human torment is given shape; when a soul has been broken and ritual torment lingers like a stain, a Veshul can congeal from the shreds of that spirit and the shadows around it. They are not summoned in the grand way of greater demons — rather they seep into existence from cruelty left uncared for, a byproduct of abuse and whispered rites performed by desperate cultists. Veshul are most often found in ruined tenements, abandoned asylum wards, or the cellars beneath brothels where secrets fester. Scholars such as Brother Maren of the Sable Archive have catalogued Veshul encounters and theorized that each Veshul carries fragments of dozens of lives; the creature's hunger is not for flesh but for recognition. The militia of the Iron Holl hold whole districts under curfew after a Veshul infestation is discovered, for these fiends spread through closed doors and small seams, driving households to paranoia. Folk remedies say that brass sigils hammered into thresholds and songs taught to children can keep a Veshul from slipping in, but only a cleansing of the original wound — and sometimes a funeral rite for the crushed spirit — will truly end one.

A Veshul appears as a low, constantly shifting mound roughly the size of a halfling when at rest, but it easily stretches into a sinuous column to slide through gaps. Its surface is glossy-black like wet oil, but under close inspection it is composed of layered silhouettes of human limbs and faces pressed together in perpetual torment. Individual faces open and close their mouths, eyes glide beneath the surface, and thin tendrils of shadow extrude like fingers that dissolve into smoke. When moving, the creature elongates into thin, ribbon-like streams that can flow under doors or through the seams of packed crates. Texture is slick and reflective; where it touches skin the area goes cold and collects a faint smear of gray residue that fades after an hour. Scale reference: at rest it is about knee-high to an average human; when slipping through cracks it can become a ribbon the width of a finger.
