Earlier this week 'Game of Thrones' let slip a bit of insight into the fifth season in that the globe-trotting HBO fantasy drama would next head to Spain to stand in as a new Westeros location, though precisely which couldn't be said for sure. Now, a new casting call reveals an extensive roster of characters drawn from, and inspired by George R.R. Martin's books, which seems to suggest which 'Game of Thrones' location Spain may become.

From WinterIsComing, the latest intel on 'Game of Thrones' season 5 suggests that we'll be spending a fair amount of time in Dorne, considering what book readers know to be the outcome of next Sunday's climactic "The Mountain and the Viper." Most notably, the season 5 casting call also seems to continue the practice of picking and choosing from Martin's more recent books (hurry up, George!), and consolidating a few characters like the "Sand Snakes."

See for yourself:

Prince Doran Martell – Doran is described as the major new player this year, appearing in multiple episodes. The fifty-something prince uses a wheelchair, is reclusive and rules wisely. It appears the show is looking to continue the trend it started with Pedro Pascal, and cast Latino actors for the Martell clan.

Prince Trystane Martell – Trystane, the handsome fiance of Princess Myrcella, is being aged up to 18.

Areo Hotah - Doran’s personal bodyguard will appear throughout the season, assisting the prince with his duties. The show is particularly looking for a black actor to fill the role.

The Sand Snakes, Oberyn Martell’s bastard daughters (with ages ranging 18-25):

Obara Sand – The eldest and most athletic Sand Snake will be having a major fight scene with a series regular character- not one who crosses her path in the books. This is an interesting change.

Nymeria Sand – Nymeria is described as “mixed race,” with her father being the fairer Oberyn and her mother being darker skinned. The second oldest of these Sand Snakes, she’s beautiful, emotional and very strong.

Tyene Sand - The youngest of the Sand Snakes that we meet uses her wits and seductive powers, and is less of a physical fighter than the other Sand Snakes. She is just as deadly as her sisters, however, but her weapon is poison.

High Sparrow - The books’ pious head of a religious movement will be appearing in several episodes in season 5.

Septa Unella – The show is looking for a character actress to play the imposing and unrelenting septa who spends a lot of time with a major series character next year.

Maggy the Frog- A fortune teller in 'A Feast for Crows,' she’ll be in one episode next year.

Lollys Stokeworth – Just last week in “Mockingbird,” Bronn announced his intention to marry Lollys, whom Tyrion considers “dimwitted.” It looks like the sellsword will still be around next year.

Yezzan - A sleazy Meereenese slave owner.

The Waif – The strange child from the books that Arya encounters will likely be played by an older actress, one in her later teens, and we understand the show is specifically looking for a woman of East Asian descent for the part.

Three episodes remain in the current fourth season, and while we don't know exactly where they might diverge from the books (considering some wild detours already taken), the season 5 casting call definitely has us excited to see some new corners of Westeros next year. What do you think? Are any of the apparent changes too egregious to enjoy? Tell us what you want to see from the final three episodes of 'Game of Thrones' season 4, as well as the fifth season in 2015!
