J.K. Rowling gave fans a treat Tuesday morning. While it wasn't butterbeer or chocolate frogs, the "Harry Potter" author unveiled a redesigned Pottermore website, while also releasing new material about the family background of James Potter, Harry's father.

"New information will be revealed about the characters, places and magic you’re familiar with, as well as introductions to a few new characters, places and notions," Rowling said in a statement on the website.

Rowling's site is dedicated to all things Harry Potter and is loaded with information for fans to read and explore. It focuses on exploring the unknown parts of the Harry Potter world.

The "Harry Potter" author disclosed the history of the Potter family, including how the family became rich and Harry's grandparents, Fleamont and Euphemia. It turns out, Fleamont and Euphemia were the ones who gave James the invisibility cloak.

"Fleamont and Euphemia lived long enough to see James marry a Muggle-born girl called Lily Evans, but not to meet their grandson, Harry. Dragon pox carried them off within days of each other, due to their advanced age, and James Potter then inherited Ignotus Peverell’s Invisibility Cloak," the essay explains.

The invisibility cloak originally made it's way into the family around the 12th century, when Hardwin Potter married Iolanthe Peverell. Peverell received the cloak from her family because she was the eldest and there were no male heirs. This started the tradition of the cloak being passed down to the eldest child.

In addition to new essays and information about characters from the Harry Potter novels, the site will also have news about the upcoming spinoff film, "Fantastic Beats and Where to Find Them." The site will also offer writing by "The Pottermore Correspondent," who promises to "bring you new stories, new magical experiences, new interviews, and new sneaky-peeks behind the scenes every day until the end of time and/or the Internet."

“Fantastic Beasts and Where to Find Them” is scheduled to hit theaters Nov. 18, 2016. Rowling is writing the screenplay with the assistance of “Harry Potter” veteran David Yates.
