Yaya Ceravieja
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).
