Hags
Completely based on myth
The word hag is a an old english translation of the modern word witch. They are described as wretched old women with the ability to fly on objects, create animated objects, and steal children. Green hags are based on the more modern rendition of hags, that being green skin and an affinity for tragedy. Night hags are based on the english and North American settler's folklore. They are able to cause terrible dreams and become ethereal. Sea hags seem to have been based on the northern english Peg Powler myth, a woman with greenish-blue skin that would drown children by pulling them underwater.
Sea hags are the weakest and most ugly of hags. They dwell underwater and have a symbiotic relationship with other aquatic horrors. They have seaweed hair, lifeless glassy eyes, and blueish scaled skin as well as aquatic adaptations.
Green hags have long grey hair and repulsive warty skin. They're the most well rounded hags and can mimic speech and even become invisible.
Night hags are the most powerful and magical of the hags. They have long left the fey to become fiends, now scavenging dreams to sell souls to each other. They have purple, freckled skin and long bronze horns coming from there long foreheads.
