Witches

Witches (魔女 - Majo) are the fate of all those contracted to become Puella Magi. Upon the corruption of their Soul Gem, the Magi are transformed into hideous, near-mindless monsters devoid of anything but utter despair. Not much is known about the 'culture' of witches, beyond the fact they have their own, eldritch dialect and written language in the form of runes. It is said that a witches form reflects the mind and thoughts of a magi the moment before they despaired, creating an intricately woven web of fantastical and magical, if somewhat disturbing designs and imagery.

Rebellion gave us a deeper look into what it means to become a witch, and it is possible that (in the magi's mind) the world continues on without change while the witch rages on continually outside.

Witches, though dangerous, are often the favorite "prey" of the magic-eating Archfiends, who crave it above all other things.
