'Game of Thrones' Season 6 Spoilers, Release Date & Cast: Bran Stark Has a Vision of Lyana Stark at Tower of Joy [Rumor]

The rumor mill about "Game of Thrones" Season 6 continues to expand as keen GoT watchers caught sight of some members of the cast in Spain.

Fan-based website Watchers on the Wall translated Spanish website Los Siete Reinos which spotted that some of the cast and crew in the Guadalajara, Spain's Castillo de Zafra.

Apparently, they are currently filming scenes for the sixth season of the "Game of Thrones" set in the Tower of Joy and are staying at the nearby town of Teruel, Spain.

For those who were not able to catch up to past reports, the Tower of Joy is a significant part of Jon Snow's lineage since it was rumored to be the place where Lyanna Stark was kept by Rhaegar Targaryen prior to her death.

It was then that Lyanna allegedly gave birth to Jon and made her brother, Ned Stark promise to care for the child whom he now claims to be his bastard son.

The big news cited by the Spanish website's extensive report is that Isaac Hempstead-Wright, who plays Bran Stark, was seen there leaving the outlet to assume that the Tower of Joy would most likely be presented in his visions.

According to Watchers on the Wall, tying the Tower of Joy to another major character like Bran is something that "makes sense" particularly if the story is deeply tied to House Stark.

Aside from Bran Stark being in the Tower of Joy, two actresses were also reported to be filming at the Castillo.

According to L7R, one of the two ladies would be starring as Lyanna, leaving the other with what seems to be a new character to be introduced in the series' new season.

L7R guesses that the second actress would be starring as either Ashara or Ellaria while Watchers on the Wall thinks that she may be there to portray Wylla, the woman who was referred to as Jon's mother in future references.

Meanwhile, another report from Watchers on the Wall revealed that another set of cast and crew are filming a big battle at Saintfield, Northern Ireland.

According to the report, the battle is set to be part of season 6's episode 9 which has repeatedly been called the "Battle of 6 Armies" and is described by the outlet as "an epic battle heretofore unseen on either the big or small screen."

Two of these six armies are said to be bearing the logo of a Direwolf and a Mormont bear based on a leaked photo posted with the report.
