Nuckelavee

Nuckelavee is a hostile Fae—an ocean-born, horse-like apparition fused unnervingly to a rider—most often seen at the edge of tidal flats or peat bogs. Smell: a corrosive mix of sea-salt, tar and hot iron that makes the nostrils sting. Sound: a hollow, surf-like slap of hooves and a low rasping exhale that seems to carry across marsh and stone. Temperature: the air around it grows oppressively warm and clammy, wilting vegetation and leaving a faint, sickly sheen on puddles. Field style notes: sightings favor dusk or storm-swirled evenings; the creature moves with the force of a breaking tide and leaves scorched hoof-prints where healthy grass once grew.
