A witch is anyone who practices witchcraft (ie herbology and other holistic practices). In game they are wizards because they practice wizardry (ie alchemy, manipulation of magical energy or exploitation of science) A warlock is any witch or wizard cast out from the circle and forced to work alone or in a secret cult. Gender means absolutely nothing in determining the title- major misconception. Of course I'm referring to historical, real life versions of the terms. Not science fiction such Harry Potter. Stories like that can make up their own rules.
