Eretiku/Eretnik/Elatoamsk/Eretitsa/Eretnitsa

The Eretiku is a creature from Russian mythology. This creature is seen as the female version of Erestun. They are thought to be deliberate blasphemers who practice black magic or women who sold their souls to the devil and return from the grave. They take the form of old women and seek out others of their kind to form covens. It can induce a sickness that causes the life force and sanity to begin wasting away, simply by staring into someone’s eyes. If they’re not strong enough to physically manifest, they take the form of a ghost that can manipulate physical objects. In this form, they rise from the graves they rest in at night to make disruptive noises.
