But for a brief moment during the opening episode of Game of Thrones Season 7, fans went wild as one of the characters made a subtle reference to JK Rowling's wizarding world.
Earlier this year, to celebrate the 20th anniversary of the first novel, the publishing house released four new editions of the book, one for each of the houses featured at Hogwarts - Gryffindor, Hufflepuff, Ravenclaw and Slytherin.
Fans of the "Harry Potter" franchise took to Twitter once news spread of the upcoming additions. A new pair of books spotlighting the historical significance and cultural importance of the wizarding community is arriving by owls this fall.
Eddie Newquist, chief creative officer of GES, added: "GES is delighted to be a part of creating a new way for fans to experience the world of Harry Potter, this time in a holiday setting".
The second is called Harry Potter: A Journey Through A History of Magic, and will be a bit broader, with a focus "from alchemy to unicorns, ancient witchcraft, to Hogwarts".
Back in 2007, when the last Harry Potter book came out, Potterheads across the globe were saddened by the end of the book series. That matches the structure of the exhibition at the British Library, titled Harry Potter: A History of Magic; the exhibit will feature potions, herbology, and care of magical creatures among other subjects, so the book will likely include those topics.
