Location: 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.

Founder: 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.

Isolt was now quite alone in a harsh, foreign country and, as far as she knew, the only witch for hundreds if not thousands of miles – her partial education by Gormlaith had not included information about Native American wizards. However, after several weeks alone in the mountains, she met two magical creatures of whose existence she had hitherto been ignorant.

Salazar Slytherin's indirect involvement: Slytherin’s wand remained inactive following Gormlaith’s command in Parseltongue. Isolt could not speak the language, but, in any case, she no longer wanted to touch the wand that was the last relic of her unhappy childhood. She and James buried it outside the grounds.

Ilvermorny Today: As might be expected of a school part-founded by a No-Maj, Ilvermorny has the reputation of being one of the most democratic, least elitist of all the great wizarding schools.

Should more than one carving signify its wish to include the student in its house, the choice rests with the student. Very rarely – perhaps once a decade – a student is offered a place in all four houses. Seraphina Picquery, President of MACUSA 1920 - 1928, was the only witch of her generation so honoured, and she chose Horned Serpent.

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.
