Well, if ever we showed disappointment with Game of Thrones Season 6 snoozing its way through Comic-Con without a hint of casting, the world of Westeros is more than making up for it. On the heels of adding Ian McShane, Game of Thrones has added Star Wars star and the all-around prolific Max von Sydow to the cast, and we actually know his role!

According to Entertainment Weekly, the revered Sydow will appear as someone we’ve already met, replacing actor Struan Roger as the Three-Eyed Raven glimpsed in Season 4 finale “The Children.” We’ve known that Isaac Hempstead-Wright’s Bran would return in Season 6, following the character’s absence this past year, and the addition of Sydow as Bran’s Greenseeing tutor casts a large shadow on the character’s significance this year.

That said, EW notes that while Sydow is already on set filming in Belfast, the actor follows McShane in that neither are “expected to have a lot of screen time next season, but both roles are crucial in their own way.”

Elsewhere of Game of Thrones Season 6 (which may not prove so penultimate as we’d thought), we know that casting on a number of other new roles suggests we’ll follow Samwell Tarly on his departure from the Night’s Watch, while others seemingly confirm we’ll pick up with George R.R. Martin’s discarded Iron Islands subplots, and additional locations point to a number of flashbacks.

Apart from a list of directors, debate continually rages as to whether Kit Harington’s Jon Snow will participate in Season 6, even as Harington can clearly be seen in Belfast, and story logistics seemingly confirm scenes set at The Wall in Season 6.

That’s two major additions thus far, but who else might join the world of Westeros when Game of Thrones Season 6 bows in 2016?
