Danish actor Pilou Asbæk has appeared" Lucy," "The Borgias," and "Borgen."

He will be played by Danish actor Pilou Asbåk on the upcoming sixth season, Variety reported.

You may remember the actor from roles in "Lucy," "The Borgias," and "Borgen." He'll next hit the big screen as Pontius Pilate in the upcoming remake of "Ben-Hur" opposite Jack Huston.

Euron is the younger brother of King Balon Greyjoy (Patrick Malahide), and the eldest uncle of Theon (Alfie Allen) and Yara Greyjoy (Gemma Whelan).

Euron (Pilou Asbæk) is the eldest uncle of Yara (Gemma Whelan) and Theon Greyjoy (Alfie Allen) on "Game of Thrones."

In the books, Euron had sex (or raped) one of his brothers' wives. For that, he was banished from the Iron Islands, the land ruled over by his family and specifically his older bother Balon.

His casting means that the Kingsmoot may be ahead. A Kingsmoot is a captains' vote to choose the king of the region. If a Kingsmoot is going down, then that means Balon is dead. And if the show goes the way of the books, Euron is chosen to rule after he promises to bring down their enemies with dragons. That means his path will cross (possibly romantically) with "Mother of Dragons," Daenerys Targaryen (Emilia Clarke).

Asbåk joins two other newcomers for Season 6: Ian McShane in an unspecified role, and Max von Sydow, who will take over the role of Bran Stark's (Isaac Hempstead Wright) mentor, the mysterious Three-Eyed Raven.

"Game of Thrones" returns to HBO in Spring 2016.
