One weird misconception that’s propagated is that the Acheri, the disease-causing ghosts of little girls that live in the mountains and react to the color red, are Native American. For instance, as in the image above by Robert Ingpen from the Encyclopedia of Things That Never Were, which has somehow ended up without attribution on Wikipedia.
Except they aren’t.
Acheri are Indian. As in from India, such as in Kumaon in hilly Uttarakhand.
How this came about is unclear, but I think hypercorrection of “Indian” coupled with an appearance in the EoTTNW (plus a suitably haunting artwork) led to the American version being popularized.
