Green hag

Green hags use their magical powers to lure innocents into their traps. They will assume the form of beautiful women and enter a populated area to find a young man or woman to corrupt with vices. They will use their ability to mimic animal noises to lure children into the swamp, where they are captured and devoured.

Physical description
A green hag is about the same height and weight as a female human. They appear to be ugly crones with twisted bodies and wretched features. Their mouths are filled with rotten teeth, often coming to points which are used to eat humanoid flesh. Their fingers end in long, blackened claws. Green hags are known by many other names, including swamp hags and river hags.

Lair
Green hags are horrible, cruel, fey-like women found in desolate swamps and dark forests. They delight in destroying beauty and purity, wanting to match it to their own ugly, debased selves.
