"Fantastic Beasts and Where to Find Them" is a fantasy book written by British author J.K. Rowling. Originally published in 2001 as a companion book to the Harry Potter series, it was presented as a textbook used by Hogwarts School of Witchcraft and Wizardry students. The book, authored in the wizarding world by Newt Scamander, catalogs a wide range of magical creatures, providing information on their habits, habitats, and classifications. In 2016, the book was adapted into a film series set in the same magical universe, exploring the adventures of Newt Scamander as he travels to New York City in the 1920s to collect magical creatures and encounters various challenges and mysteries. The franchise has since expanded, with multiple films and a promise of more magical adventures in the wizarding world.
