The "Once Upon A Time" season 6 premiere will be a loaded hour as the heroes deal with the arrival of Mr. Hyde (Sam Witwer), which is bad news for Storybrooke.

In a deal with Rumple (Robert Carlyle), Hyde was allowed to bring residents of The Land of the Untold Stories to the town. Regina (Lana Parilla) and Emma's (Jennifer Morrison) combined powers did nothing to stop him.

Hyde is looking to relocate the characters in Storybrooke in "Once Upon A Time" season 6, but not everyone is happy to get a new home as it meant continuing the tales they would rather want to be frozen.

In an interview with Entertainment Weekly, "Once Upon A Time" executive producer Edward Kitsis explained what The Land of Untold Stories is all about and who lives — or used to live — there.

"They're characters who we haven't touched upon in our show, and – for whatever reason – have found their way out of the Enchanted Forest or whatever realm they were living in into this other place," the EP said.

"What we're going to see is that they are a bunch of characters who have left their own story for various reasons, so they didn't like how it ended, they didn't like how they were going, they needed to be on the run," he went on to say.

In the first five episodes of "Once Upon A Time" season 6, there will be a lot of characters that fans will see, starting with Morpheus (Giles Matthey).

Jekyll (Hank Harris) and Hyde will also be a big part of the initial episodes, as well as the story on how Rumple and Hyde have become connected.

The "Once Upon A Time" season 6 premiere synopsis suggests that Rumple had help from a "stranger" with regards to Belle's (Emilie de Ravin) condition. Whether or not Hyde has something to do with it will not be kept secret for long.

The initial installments of "Once Upon A Time" season 6 will also reveal Jasmine (Karen David) and her mission, Aladdin (Deniz Akdeniz), a Savior like Emma, and Jafar (Oded Fehr) and his ruthlessness.

"Once Upon A Time" season 6 will premiere on Sunday, Sept. 25, at 8 p.m. ET on ABC.
