( CNN ) -- No tricks here , just the treat : In honor of Halloween , J.K. Rowling is delving into the back story of one of `` Harry Potter 's '' more twisted Hogwarts professors . On Rowling 's Pottermore website , the best-selling author has crafted a story about the life of Dolores Umbridge , whom fans will remember for her toad-like appearance , her hair bows and the gruesome way she chose to punish students . It turns out that Umbridge was inspired by a real person . There was a teacher of Rowling 's whom she `` disliked intensely on sight , '' and it seems the feeling was mutual . To be clear , this teacher was n't `` the real Dolores Umbridge , '' but her love of childlike accessories definitely inspired the character . `` What sticks in my mind is her pronounced taste for twee accessories , '' Rowling says in an essay about the character . So although this teacher did n't `` look like a toad , was never sadistic or vicious to me or anyone else , and I never heard her express a single view in common with Umbridge ... it is true to say that I borrowed from her , then grossly exaggerated , a taste for the sickly sweet and girlish in dress . '' As for Umbridge 's love of kittens , that was inspired by a former officemate of Rowling 's , whose adoration for small furry creatures was in contrast with `` a lack of real warmth or charity . '' New 'Potter ' character finds spotlight . `` So Dolores , who is one of the characters for whom I feel purest dislike , became an amalgam of traits taken from these , and a variety of sources , '' Rowling explains . `` Her desire to control , to punish and to inflict pain , all in the name of law and order , are , I think , every bit as reprehensible as Lord Voldemort 's unvarnished espousal of evil . '' If you have an account on Pottermore , you can read the story there , or you can check it out on Today.com . 'Harry Potter ' returns in a short story . Up next from the world of `` Potter '' are three movies that will follow the adventures of the author Newt Scamander years before his textbook `` Fantastic Beasts and Where To Find Them '' would be studied at Hogwarts . The first installment , also titled `` Fantastic Beasts and Where To Find Them , '' has Rowling writing the screenplay and David Yates on board to direct . That movie will arrive in 2016 , followed by two more installments in 2018 and 2020 .
