(CNN) — The Harry Potter world is growing — again.
In four stories set to debut this week on Pottermore, the official Harry Potter site, author J.K. Rowling is introducing aspects of magic in North America, helping set the stage for this fall’s premiere of the new Potter movie, “Fantastic Beasts and Where to Find Them.”
“The official story is never the whole story,” says a video, which appeared on EW.com.
The tales span the history of the U.S., including a chronicle about Ilvermorny, the American wizarding school; a story about skin-walkers, drawn from Native American legends; and a piece based on the Salem witch trials.
The final story concerns the Magical Congress of the United States of America. Whether it’s less contentious than the real Congress of the United States of America is anyone’s guess.
Each story will roll out at 2 p.m. GMT each day (9 a.m. ET), beginning Tuesday.
The new works add to the Potter onslaught coming this summer, when the play “Harry Potter and the Cursed Child” opens. It will be followed by “Fantastic Beasts,” which Rowling said last week will be three films, not just one.
And fans, no need to hold your breath.
“As always, remember to breathe,” suggested the Pottermore site.
