Sorceress: A sorceress is a female who normally practices Black Magic. They are not all necessarily ugly, unlike the hag.
Enchantress: A seductive female, enchantresses normally use their magic and bodies to seduce men for their own needs. They are typically quite selfish, and will go to any length to get what they desire, even if it's just a man.
Hag: Much like the stereotypical evil witch, hags normally have long, pointed noses and claws with greenish-gray skin. Many are known to eat children and raw liver, living within dark, secluded caves or forests. They possess archaic dark magic skills, normally more powerful than a sorceress.
Wise-woman: Like the hag, wise-women are very old, but do not all have pointed noses and sharp claws. They normally look like average elder women, and can even be of other human/humanoid races. Many are known to be master seers, miraculous advisors, and fantastic healers of magic. They are normally not evil.
