Are these really the names of the four Houses of American Hogwarts?

A software engineer named Federico Ian Cervantez claims he's found the names of the Houses in JK Rowling's North American wizarding school Ilvermorny, after stumbling across hidden code in an "under construction" quiz on the Harry Potter website Pottermore.

If he's right, American witches and wizards could be sorted into...Horned Serpent, Wampus, Thunderbird or Pukwudgie.

The find was first reported by Hypable, and RadioTimes.com has since confirmed that the names do indeed appear on the site.

Harry Potter prequel movie Fantastic Beasts and Where to Find Them is set to explore magic in the United States, and Rowling has even written some background on the history of magic in North America.

The names revealed in the site above appear to be named after creatures from Native American folklore, following on from Rowling's – at times controversial – inclusion of Navajo beliefs as part of her fictional 'History of Magic in North America' series.

The House names, linked to an unpublished webpage on Ilvermorny School of Witchcraft and Wizardry, appear in the following section of code.

We'll have to wait and see whether these Houses either are featured in the film or included once the site goes live.
