Ilvermorny statues refers to the statues made for Ilvermorny School of Witchcraft and Wizardry in honour of Isolt Sayre and James Steward who founded the school. They were carved out of marble and flanked the front doors of the castle which opened into a circular room where the Sorting ceremony took place. Isolt's statue was tended to by the Pukwudgie named William, who may be her old friend. He was very protective of it and refused to allow anyone else clean it.
