J.K. Rowling set the would-be wizarding world aflutter Tuesday when she released a new Pottermore story, outlining the four houses in Ilvermorny, the North American school of witchcraft and wizardry featured in her new Magic in North America series. Fans were quick to compare the four houses — Thunderbird, Horned Serpent, Pukwudgie, and Wampus — to the four Hogwarts houses, but Rowling shut down ideas that there is any direct correlation to Gryffindor and co. in a tweet sent out early Wednesday morning.

“There is no equivalence between Hogwarts and Ilvermorny houses,” Rowling wrote when a fan asked if Wampus was equivalent to Hogwarts’ Hufflepuff. “But don’t diss Hufflepuff!”

The new houses do have similar traits to those of Gryffindor, Ravenclaw, Hufflepuff, and Slytherin, but are also less fleshed out so far, since we’ve only read about them in one Pottermore story. (Though Pottermore does host a quiz that will sort fans into houses. Shoutout to all the Pukwudgies!)

Each house is said to embody a core part of the ideal wizard. Per Pottermore’s descriptions, Thunderbird (Rowling’s own house) identifies with the soul of the wizard and favors adventurers, Horned Serpent represents the mind of the wizard and favors scholars, Pukwudgie speaks to the the wizards’ hearts and favors healers, and Wampus is the body of a wizard, favoring warriors.
