J. K. Rowling has updated Pottermore
with new information about the great North American school of magic, Ilvermorny.
The great North American school of magic was founded in the seventeenth century. It stands at the highest peak of Mount Greylock, where it is concealed from non-magic gaze by a variety of powerful enchantments, which sometimes manifest in a wreath of misty cloud.
Founded by an Irish witch:
Isolt Sayre was born around 1603 and spent her earliest childhood in the valley of Coomloughra, County Kerry, in Ireland. She was the offspring of two pure-blood wizarding families.
Names of the four houses:
Horned Serpent – a ‘great horned river serpent with a jewel set into its forehead’
Pukwudgie – ‘a short, grey-faced, large-eared creature’
Thunderbird – a creature that ‘can create storms as it flies’
Wampus – ‘a magical, panther-like creature that is fast, strong and almost impossible to kill’
The sorting ceremony:
The Sorting Ceremony is not the only major difference between Hogwarts and Ilvermorny (though in so many ways the schools resemble each other). Once students have been allocated a House they are led into a large hall where they select (or are selected by) a wand. Until the 1965 repeal of Rappaport’s Law, which enforced very strict conformity with the Statute of Secrecy, no child was allowed a wand until they arrived at Ilvermorny. Moreover, wands had to be left at Ilvermorny during vacations, and only upon attaining seventeen years of age was the witch or wizard legally allowed to carry a wand outside school.
The robes of Ilvermorny are blue and cranberry. The colours honour Isolt and James: blue because it was Isolt’s favourite colour and because she had wished to be in Ravenclaw house as a child; cranberry in honour of James’s love of cranberry pie. All Ilvermorny students’ robes are fastened by a gold Gordian Knot, in memory of the brooch Isolt found in the ruins of the original Ilvermorny cottage.
