Magrat Garlick (pronounced Magg-rat) is the daughter of Simplicity Garlick, granddaughter of Araminta Garlick and niece of Yvonnel Garlick. She was the original Maiden in the Lancre coven, which consisted of herself, Granny Weatherwax and Nanny Ogg. She is often described as "a wet hen", generally by Granny Weatherwax. Magrat believes in crystals, folk wisdom, and cycles of nature, and is overall a gentle parody of New Age pagans.
Despite appearances, beneath her silver jewelry and heavy eye makeup, Magrat is surprisingly practical. She can defend herself physically when necessary, and is capable of performing impressive feats of real magic (as seen in Wyrd Sisters when Magrat uses her magic to turn the old wooden door into a rising oak—a display that impresses even Granny Weatherwax). Magrat's gentle personality allows her to serve as a mediator between the often-clashing Granny Weatherwax and Nanny Ogg, but she does occasionally display a strong temper herself. In Witches Abroad Magrat was chosen to serve as a Fairy Godmother, but her inability to master the use of the wand (which had a tendency to reset to "pumpkins") prevented her from taking full advantage of the powers associated with this position. Magrat is technically a better doctor than the other two witches, since she actually believes in herbalism while Granny tends to use whatever plant or bottle of coloured water comes to hand as a prop for her headology (in this case the placebo effect), as explained in Lords and Ladies.
After a long engagement, Magrat became Queen of Lancre by marrying King Verence II. As of Carpe Jugulum the couple has one daughter, Princess Esmerelda Margaret Note Spelling. This unusual name was the result of Magrat's attempt to correct a mistake made by her own mother, who had intended for Magrat to be named "Margaret" but was unable to spell the name properly when she wrote it down for the priest. In an effort to ensure the proper naming of her child, Magrat appended "Note Spelling" in the note she passed to the priest. This back-fired when he read out the complete sentence, and was mortified afterwards, but the deed had been done and no attempt to change it could be made.
Magrat renounces witchcraft shortly before her marriage, partially to prepare for her duties as queen, but mostly out of frustration with the way she is treated by the senior members of the Lancre coven and is supplanted by Agnes Nitt after the events of Maskerade. Her absence from Maskerade seemed to confirm that Magrat had retired from her career as a witch, but after Princess Esmerelda's birth she was forced to assume the Mother role in the coven when Granny Weatherwax decided to temporarily step down during the events of Carpe Jugulum. Nanny was none too pleased with this development, as Magrat being the Mother forced Nanny "to be the... Other One". Despite her new (temporary) role, at the end of the novel, she was asked, and acquiesced, to make tea by Granny Weatherwax, a role usually performed by the Maiden (in this case, Agnes Nitt).
Magrat makes a brief appearance in I Shall Wear Midnight, alongside her husband Verence as guest to the wedding of Roland de Chumsfanleigh (the new Baron of the Chalk) and Letitia Keepsake (the daughter and only child of the Duchess and late Duke of Keepsake), and was flown down from Lancre by Granny Weatherwax and Nanny Ogg. In The Shepherd's Crown, she is one of the people across the Disc who feels Granny Weatherwax's death when she dies of old age; she and Verence were attending a conference in Genua at the time. It is also revealed that since the events of Carpe Jugulum Magrat and Verence have had two more children.
