The Scots author will be releasing the first instalment, entitled History Of Magic In North America, in four parts on her website Pottermore over the next week.
She will be uncovering topics including Ilvermorny, the name of the North American wizarding school; the Native American legend of skin-walkers; the Salem witch trials; and The Magical Congress Of The United States of America, the US equivalent of the Ministry of Magic.
A post on Pottermore read: “Magic in North America will bring to light the history of this previously unexplored corner of the wizarding world in the run-up to Fantastic Beasts And Where to Find Them. And you’ll want to get up to speed before the film comes around in November.”
A trailer released to accompany the news warned: “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.”
The new history comes ahead of the November release of the film Fantastic Beasts And Where To Find Them, starring Eddie Redmayne as Newt Scamander and set in 1920s wizarding New York City.
The first part of History Of Magic In North America will be published at 2pm on Tuesday March 8, with stories released at the same time daily until Friday March 11.
