Hagraven is a humanoid creature that can be encountered in regions of High Rock and Skyrim. According to legend, they were apparently once witches, but exchanged their humanity for the ability to become hagravens.
Hagravens bear a vitriolic hatred against nature, and hunt down spriggans to capture and sacrifice. The Forsworn revere them greatly, and it is noted that the hagravens were in the Reach since "the beginning." Once, they served as mercenaries alongside Bjoulsae horsemen, during the battle of Ain-Kolur. They are known to ally themselves with the Reachmen.
Hagravens are hideous, avian-like, female humanoids with scraggly gray hair, pale skin, hooked noses, and solid black eyes. Their limbs are long and bony, and their hands and feet each have four digits ending in sharp talons. They dress in tattered black garments and have black raven feathers bound to their shins and forearms.
