This is going to be a big week for Harry Potter fans. Specifically, those who care about the Wizarding World in the North America.

J.K. Rowling and Pottermore are set to unveil four new features about the U.S. Wizarding School Ilvermorny, the Salem Witch Trials, a group called Skin-Walkers, and the Magical Congress of the United States of America beginning this Tuesday, March 8. One will be released each morning between tomorrow and Friday.

A promotional video Pottermore has created for their “Magic in North America” series is hyping these up to be big deals.

“The Wizarding World you thought you knew is much larger than you imagined. History has many secrets,” the narrator says. “The official story is never the whole story. Look beyond the surface and you will find another world running parallel to our own. A secret world where magic is real. Ilvermorny, Skin-Walkers, the Witch Trials, and the Magical Congress of the United States of America. These aren’t myths. For the history of America is more amazing than you could ever imagine. Everything you think you know is about to change.”

When the video speaks of Ilvermorny, Skin-Walkers, and the witch trials, interesting and beautiful visuals appear. For example, this appears to be our first look at Hogwarts USA:

This shot appears to hint at the story behind the Skin-Walkers. They don’t like magic, do they?

And here’s a glimpse of the witch trials.

These reveals come as fans gear up for Fantastic Beasts and Where to Find Them, the Wizarding World spinoff movie opening in theaters this November. Newt Scamander’s adventures will be taking place in America, and a lot of this new information from Pottermore is expected to tie into the story.

J.K. Rowling revealed new information about three other Wizarding Schools in other areas of the world in January. At the time she also shared the name of the North American Wizarding School, but unfortunately, the name was all she shared.
