The stories about deer-like skinwalkers always felt like they came from a deep, uneasy place in the traditions. They're not your standard boogeyman tales. From what I've gathered, it's less about a specific 'deer legend' and more about the shape-shifting itself being tied to places of power and specific animals. Deer are incredibly significant in many Nations—they're messengers, guides, providers. So the corruption of that form, a skinwalker wearing a deer hide, is a profound violation. It twists something sacred into a predatory, unnatural thing. That's the real horror: it's not just a monster, it's a perversion of a relationship.
I remember a Diné friend once mentioned how certain animals are considered yee naaldlooshii, 'with it, he goes on all fours.' The power comes from a dark place, a rejection of harmony. So a deer-skinned walker isn't inspired by a 'deer legend' per se, but by the broader, tragic lore of witchcraft that abuses the sacred bonds between people, animals, and the land. The deer just becomes a potent, heartbreaking vessel for that evil because of its cultural weight.
