Los Angeles - JK Rowling has teased Harry Potter fans ahead of the release of Fantastic Beasts and Where to Find Them.
The 50-year-old author has announced the unveiling of a four part original series, titled The History of Magic in North America, on Pottermore.
A post on the website reads: "The first instalment of this exciting new series is called History of Magic in North America and will be published on Pottermore in four pieces, starting tomorrow at 2pm GMT. Another piece will be revealed each day at 2pm until Friday 11 March.
"You've got four days of new writing by JK Rowling to look forward to - as always, remember to breathe."
The four stories support the release of the hotly-anticipated movie in November, which stars Eddie Redmayne and is set 70 years before the initial Harry Potter stories began.
The message continues: 'We were able to share with you the name of the North American wizarding school earlier this year, but there's just so much more to tell you about witches and wizards across the world.
"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."
