There's two sorts of "Witches":>Witch in "name only"
These are exclusively women who've either gone into druidism, demonology or have otherwise dabbled in some form of mixed hedge magery and naturalism whether good or bad.
Witches in "name only" often get a bad rap since they have an amazing knack for staying suspiciously young, being promiscuous without getting pregnant or diseased and often hovering below the radar of civilized society and academic magic-users.
Overall they're usually nice enough women that live normal enough lives with the title of "witch" often given to these ladies by other women looking to chastise them or shame them for looking so good whilst being unmarried and middle-aged. This name calling only gets worse as when they do marry these "witches" often scoop up the youngest & cutest farm boys, huntsmen and outdoorsmen (often entranced by huge herbalogy bosoms) and in doing so earn themselves the title of "cradle robbers". >True Witches
Horrible, awful, fucking horrifying, dreadful magical creatures that at one point "were" women.
Magic is an expression of your soul, but so is your physical body, so what do you suppose happens when your soul forgets what you look like or for that matter you stop caring what you look like for the sake of power and magic?
Witches are essentially magic wielding female mutants made twisted and crooked by practicing such hideous spells and rituals: Murdering and skinning beautiful men and women (often prostitutes) so they can wear their hides and turn into them to later lure children so they can rape and eat them to extend their own wretched lives.
Casting and spreading warts onto peoples shoulders, backs, cheeks and other places so they can see through them and spy on villagers and other innocent folk.
Snatching up and kidnapping babies so they can slowly and painfully turn them into familiars or drain the blood from their bodies to produce misty miasmas that obscure their homes.
