The most powerful witch on the Discworld, though she would phrase it differently. Granny Weatherwax believes that the most dangerous thing anyone can do is decide they are the hero of their own story, and she watches herself for signs of that mistake more carefully than she watches anything else. Her speciality is Borrowing — riding the minds of animals — and Headology, the art of making people believe things are happening rather than actually making them happen. She is formidable, lonely, sometimes cruel in her righteousness, and utterly unwilling to be anything other than what is needed.

Mother of fifteen children by various husbands, grandmother of an uncountable number, and the second of the Lancre witches. Where Granny Weatherwax is steel, Nanny Ogg is warmth — she likes people, enjoys company, and has a talent for getting information out of everyone she meets while giving nothing important away. Her cat Greebo is enormous, battle-scarred, and considered a public menace. She brews extremely strong cider and has written a cookbook of considerable notoriety. She is, in her way, as formidable as Granny — just more comfortable about it.

The third of the Lancre witches and eventually Queen of Lancre after marrying King Verence II. Magrat is earnest, sensitive, and has a deep interest in crystals, herbs, and the more romantic aspects of witchcraft — interests that Granny Weatherwax finds mildly exasperating. She is often underestimated, including by herself, which tends to be a mistake. Her arc through the Witches sub-series is one of the most satisfying in Discworld: from insecure novice to someone who discovers, to general surprise, that she contains considerable depths.

A large-voiced, large-framed young witch from Lancre who goes to Ankh-Morpork to sing opera and ends up investigating murder instead. Agnes has an inner persona she calls Perdita who is everything Agnes is too sensible to actually be. She has one of the greatest singing voices on the Disc, able to harmonise with herself. She joins the Lancre coven as the third witch after Magrat becomes Queen, and brings a certain grounded practicality alongside a permanent internal argument with herself.

A witch from the Chalk, a shepherd's daughter who began her career at nine years old with a frying pan and a horde of small blue Scottish men. Tiffany has First Sight (the ability to see what is really there) and Second Thoughts (the ability to think about your own thinking). She is practical, stubborn, and deeply attached to the land she comes from. Over five books she grows from a child who wants to be a witch into a young woman who understands what that actually means — someone who does the hard, unglamorous work of looking after people, because no-one else will.
