'Game Of Thrones' Season 7 Spoilers, News & Updates: Euron Vs. Yara & Theon Greyjoy Battle To Unfold?

Viewers of "Game of Thrones" should prepare for another massive battle in Season 7. Reports say that the Greyjoy siblings, Yara (Gemma Whelan) and Theon (Alfie Allen), will finally face off against their uncle, Euron (Pilou Asbæk), in the upcoming season.

The set in Ireland has supposedly finished filming the great battle between the Greyjoys in "Game of Thrones" Season 7. Watchers on the Wall reports that the fight has taken place in the water, and unfortunately, one of the siblings has supposedly been taken by their evil uncle.

It is unclear which sibling has become Euron's prisoner, but Belfast locals are confirming that the actors are indeed in the area for the shoot. On Twitter, fans of "Game of Thrones" have been sharing photos of Gemma Whelan, Alfie Allen and Pilou Asbæk in Belfast during filming downtimes.

It should be recalled that in "Game of Thrones" Season 6, Yara and Theon escaped the Iron Islands, which Euron has taken over. Yara and Theon sailed to Meereen to seek an alliance with Daenerys, which they successfully sealed. But it looks like Euron also has something up his sleeves. The report says he's going to forge an alliance with Cersei in "Game of Thrones" Season 7.

According to Time, Euron Greyjoy is touted as "Game of Thrones'" next biggest villain, following the deaths of King Joffrey Baratheon in the earlier season and Ramsay Bolton last season. In the books the show is based from, Euron is described as a sadistic person who doesn't hesitate to sacrifice lives to win wars.

His scenes in the TV show last season were brief, as he only appeared in one episode. But despite the short appearance, "Game of Thrones" has established that he is indeed a big threat. Viewers will learn more about Euron Greyjoy's plans once the show premieres in late 2017.
