Less than a month to go and your favorite fairytale characters from "Once Upon A Time" Season 5 will grace your TV screens again. The last season left viewers dumbfounded as Emma Watson sacrificed herself and was consumed by the dark side. How will the rest of the characters of Storybrooke deal with the Dark Swan, Emma's new character as she was engulfed by the dark side? Will they be able to save her or will she be consumed by the darkness within herself.

Speculations ran high a few months ago that a new character will join "Once Upon A Time" Season 5, Merlin aka Sorcerer, portrayed by Elliot Knight will play a big part in saving Emma.

Emma Swan's son Henry Daniel Mills played by Jared S Gilmore together with Josh Dallas' Prince Charming aka David Nolan, Ginnifer Goodwin's Snow White aka Mary Margaret Blanchard, Colin O'Donoghue's Captain Hook and the rest of Storybrooke will join forces and search for Merlin's whereabouts.

However, International Business Times revealed that the team's search turned out futile which may lead Henry Daniel Mills to make a decision to rewrite the whole book in order to rescue his mother, Emma, from the darkness.

Way ahead before Emma became the Dark Swan, Mills had the choice to rewrite the book, but he turned down the idea and instead broke the Author's plume. But, he probably regretted his action and will otherwise exhaust all efforts to save her.

Since Henry is the book's new author, he may eventually discover a way to reverse Emma's fate. According to Entertainment Weekly, executive producer Edward Kitsis has already disclosed that "Once Upon A Time" Season 5 will see a lot of Regina Mills' adopted son being the Author.

Meanwhile, Fashion&Style has revealed that a new picture taken from the set of the ABC fairy tale drama showed Elliot Knight dressed as the sorcerer Merlin.

Merlin is described as a man with great intelligence and wisdom ahead of his years and understands in sacrificing when duty beckons, as per TV Line.

Furthemore, other cast members who will join Storybrooke are Joana Metrass as Guinevere and Liam Garrigan as King Arthur.

Pop Sugar also detailed Disney/Pixar's Princess Merida will join probably in the search for Merlin, while Rebecca Mader as Zelena and Sean Maguire as Robin Hood were promoted to series regulars.

Catch "Once Upon A Time" Season 5 on ABC on Sept. 27, Sunday at 8 p.m.
