Skinwalker

Skinwalker is a Witch/Spirit and a dangerous shapechanger that moves between human guises and animal forms. In the field it announces itself not with grand spectacle but small, uncanny details: a sudden, bone-deep chill that creeps under clothing; the sour tang of damp earth mixed with an iron note, like disturbed metal; and sounds that unsettle — a wrong syllable imitating a human voice, nails scraping at a window, or an animal cry that begins normal and ends with a staccato, unnatural cadence. Its presence is furtive and deliberate, as if an alert predator were learning how to be something else.
