Witch

Witches in The Elder Scrolls II: Daggerfall, were found near Daedric Shrines and could do "Daedric Summoning" (would summon the Daedra corrosponding to the shrine you are near) if you had a high enough reputation with the Witches and for a sum of gold. The NPC would change from a beautiful woman, to an ugly old woman holding a staff.
