Hag are a creature type used for cards that depict a kind of malevolent female faerie, bearing the appearance of a wizened old woman. Sometimes Hags are described as nightmare spirits. Hags have appeared in all colors, save red.
Hags returned with a vengeance on the plane of Shadowmoor, where these witchy creatures were known as gwyllions. Gwyllions preyed on travelers who would dare cross through the rotting farmlands and bogs they call their home. Examples are Desecrator Hag and Gwyllion Hedge-Mage
- Gwyllions are the most human-like of all Hags.
- "Gwyllion" is actually the plural in Welsh, and an individual would be called a gwyll.
