While fans will have to wait until the spring of next year for season 4 of HBO's hit medieval fantasy series, "Game of Thrones," an onslaught of spoilers and casting news may provide an exciting distraction until then.

WinterisComing.net reports that Italian-born actress Paola Dionisotti will be joining the Emmy award-winning cast for the fourth season as Lady Anya Waynwood, and a mysterious innkeeper's daughter has also been cast.

The news has been confirmed via Dionisotti's official CV, on which "Waynwood" is mistakenly spelled "Waywood," something only fans of George R. R. Martin's book series, "A Song of Ice and Fire" are likely to catch.

In the books, Lady Anya is a noble woman, the head of her house and sworn to House Arryn of the Vale. Although her character does not make her first major appearance (she was briefly present in the first book, "A Game of Thrones") until "A Feast For Crows," like other characters, she'll be making her debut in the story early as the show writers try and condense all of Martin's books into mere 10-episode seasons.

Dionisotti is best known for her work with the Royal Shakespeare Company, according to WinterisComing.net, having appeared in a variety of productions including "King John" and "Richard III," in addition to her reccuring television roles on British shows "Harbour Lights" and "Forever Green." She has also guest starred on "Doctors," "Midsomer Murders" and "Poirot."

Also joining the cast for season 4 is Gabrielle Dempsey, who will be playing the part of an Inn Keeper's daughter in the season premiere, according to her CV. Dempsey is a 2010 graduate of the Central School of Speech and Drama in London, and "Game of Thrones" will mark her first television role. It is unclear which innkeeper's daughter she will be playing exactly, as the show writers have taken quite a few liberties with the books, especially where the timeline is concerned. Season 4 will cover the second half of "A Storm of Swords," the third novel in the seven-part book series, "A Song of Ice and Fire."

"I can think of a few reasons to introduce House Waynwood earlier along with Royce, so this is more good news. Dionisotti is a  great actress, so I think she'll be a wonderful Lady Waynwood," WinterisComing.net writes, while fans have also expressed their delight at Dionisotti joining the cast in the comment section of the fan site.
