'Once Upon A Time' Season 4 Theories: Who Wrote Henry's Story Book? Plus Who Is The Sorcerer?

ABC's hit fairytale drama "Once Upon a Time" is already midway through the season and there are so many questions! Like who is the author of Henry's story book? Plus who is this almighty and powerful sorcerer? We don't actually have the answers to these questions (because if we did we'd spoil the show for you) but we've got a few good ideas. Check out these top theories on who is the sorcerer supreme and who wrote the book.

Merlin "The Sword in the Stone" - Merlin is a powerful wizard master from Disney's "Sword in the Stone" film. Merlin does not appear on the show. However, it is established in season 3, that he lives in Fairytale Land where he enchanted the sword Excalibur and hid it in Camelot. If anyone can wield power such as the hat it is him!

Sorcerer Mickey Mouse "Fantasia" - This would obviously have to be a human version of Mickey Mouse but the hat does belong to this character. Sorcerer Mickey is one of the most powerful characters in the Disney universe. Sorcerer Mickey can bring objects to life, control water and fire, fly, levitate, and more. Sorcerer Mickey most famous ability is the power to control water. Sorcerer Mickey was also shown to control the stars and comets.

Madam Mim "The Sword in the Stone" - Madam Mim is the main antagonist of "Sword in the Stone" and claims to be just as poweful as Merlin. She is an expert in dark magic and has the ability to harness such power as the hat.

Hades "Hercules" - The greek god of the underworld and main antagonist from Disney's "Hercules" movie. This guy definitely has the goods to wield an all powerful hat.

Jafar "Aladdin" - This would be an interesting plot twist and bring back Naveen Andrews who portrayed the dark sorcerer in "OUAT in Wonderland." Though he was punished and forced to serve eternity as a genie in a bottle he may have found a way out and is now a supreme sorcerer. It's a stretch but this show has a way of making the impossible possible.

As for writers of Henry's story book the list is a bit shorter. There aren't many Disney characters that are book enthusiast and powerful sorcerers.

Yen Sid "The Sorcerer's Apprentice" - Though an obscure character Yen Sid is Mickey's teacher and a powerful sorcerer. He definitely has the power and ability to create a magical fairytale book.

Aslan "Chronicles of Narnia" - Yes this is a long shot and wouldn't really make sense story wise but hey that's why it's a theory and not a fact. We've always wanted to see characters from the 'Narnia' franchise introduced in OUAT and maybe this is how Edward Kitsis and Adam Horowitz will do it.

Zeus "Hercules" - King of the Olympian Gods! Again, why not? He's powerful, legendary and all knowing. He could easily write a book based on our Storybrooke/Enchated Foret characters.
