Two new characters from the northern parts of Westeros will reportedly be introduced in “Game of Thrones” Season 6. Meanwhile, pictures from the production set of the show have leaked online.

[Spoiler alert]

According to a report by WatchersOnTheWall , Smalljon Umber will appear in the next season of the show. The character has so far not appeared in the show, but in the books Umber fights alongside Robb Stark. The report said that the introduction of the character at this juncture marks a departure from the books, in which Umber died at the infamous Red Wedding.

The other major character to be introduced in the next season is Lord Karstark. The report does not indicate the first name of the northern lord so it is still unclear which character from the books will be introduced, or if this is a new character altogether. The House Karstark is a major House in the north.

According to the report, the producers are also looking for an actor to play the role of a “rugged pirate.” The actor has to be in his 30s with a “sharp mind and machismo.” The character is described as being a “tough sort with a violent temper.”

The report speculated that the rugged pirate character will be seen in a Kingsmoot scene in “Game of Thrones” Season 6, where the people of the Iron Islands will select their new king. The new character apparently has many “forceful” dialogues with some of the “leading cast members” in the scene. The shooting for this scene is expected to take place next week in Northern Ireland.

Meanwhile, leaked photos from Almeria, Spain posted on DiariodeAlmeria shows a circular building nearing completion. The report speculated the building to be some sort of a temple. The set pieces being used in the construction are said to have been manufactured in Belfast, and have been transported to the production site by trucks.

Filming at this location for “Game of Thrones” Season 6 will take place between Oct. 10 and Oct. 23. It is still not clear which part of the fantasy world will be depicted at this site. The producers of the show have apparently hired private security to maintain secrecy at the production site.
