With only two episodes left in "Game Of Thrones" Season 4, fans are eager to hear what's next for the series. There have been some interesting rumors about characters who may appear in "Game of Thrones" Season 5.

Warning: Full "Game of Thrones" Season 4 spoilers and "A Song of Ice and Fire" discussion ahead.

Winter Is Coming reports on casting for three characters who may appear in Season 5. The warg Varamyr Sixskins is one character that WIC's source said the series is looking to cast. Varamyr first appears in "A Storm of Swords." His appearance in Season 5 would be intriguing as the series would have to use the character in a way that differs from the novels. 

Varamyr, using Orell's eagle, spots Stannis as he and his army are making their way north to the Wall. The warg also participates in the Battle of Castle Black. Varamyr, while a cool character, seemed likely to be cut from "Game of Thrones" as he serves no purpose in advancing any storylines (much like Coldhands).

Winter Is Coming's source says the series is looking for two girls that may be involved in the Maggy the Frog storyline. The scene, which appears in "A Feast for Crows," involves a young Cersei and two of her friends. Maggy the Frog is a fortune-teller who predicts a devastating future for the future queen. According to Maggy, a younger, more beautiful queen will usurp her throne and Cersei will outlive her children. This storyline makes more sense than Varamyr's appearance in "Game of Thrones" Season 5, as Cersei and Margaery will compete for power and Tommen.

The most recent news follows previous rumors of shooting locations in Spain and a casting call for several characters. The rumored list of characters focused on the Martells and Dorne, which makes sense following the death of Oberyn Martell, the Red Viper, and the upcoming storylines in "A Feast for Crows." The Sand Snakes, Oberyn's bastard children, Doran Martell, Trystan Martell and Aero Hotah are expected to appear, based on the report, and it seems likely Arianne Martell, the eldest child of Doran, will also appear.

So far the casting rumors have not included any mention of the Greyjoys, including Theon's uncles Euron and Victarion. The Iron Islands feature prominently in "A Feast for Crows" so it's likely the Greyjoys wil appear in "Game of Thrones" Season 5.

It will be interesting to see how series creators David Benioff and D.B. Weiss adapt "A Feast for Crows" and "A Dance with Dragons." The latest novels in George R.R. Martin's "A Song of Ice and Fire" series run concurrently, so there is a lot of material that can be rearranged and storylines that can be changed.
