In Diné tradition, a practitioner of corrupted medicine who gains the ability to wear the skin and shape of animals. Out of respect, the tradition holds that the subject should not be discussed casually or by name at night — the archive records accounts as submitted and adds nothing.
Field reports follow a stable pattern: a coyote, dog, or elk that moves wrong — jointed like a man, pacing vehicles at highway speed, standing upright when it believes itself unobserved — combined with an overwhelming sense of being specifically, personally watched.
The archive's standing guidance for the Four Corners corridor: do not stop for animals behaving anomalously at night, do not make eye contact, and do not bring anything from the site home with you.
