Annis hags, also called Black Annis or Black Agnes, are the most physically powerful of the hags.
Annis hags are giant crones with blackened skin; stringy, black hair; fingers that end in long talons; and sharpened teeth that look like iron nails. They stand over 8 feet tall and weigh 325 pounds. While annis hags can assume a more attractive form, they cannot change their size. Thus, they always assume the form of a gentle giantess or extremely tall woman.
Annis hags make their lairs in dark caves, burrows, and ruins, where they stalk and feed upon the unwary. Of all the hags, annis hags delight in tearing their victims to shreds with their bare hands, all while relishing in the screams of pain and terror.
