What is "ilvermorny"

Ilvermorny School of Witchcraft and Wizardry, shortened Ilvermorny, is a fictional North American school of magic in the universe of Harry Potter by author J. K. Rowling, tied in with the film Fantastic Beasts and Where to Find Them. The school was founded in the seventeenth century in Adams, Massachusetts on Mount Greylock, the highest natural point in the state. It is concealed from the non-magic world by enchantments which may sometimes appear as a cloud surrounding the peak. Modeled after Hogwarts, the school has four Houses in which the students are sorted upon arrival.
