Set photos reveal that Theon (Alfie Allen) and Euron (Pilou Asbæk) are fighting each other. Meanwhile, several cast members were reported to be heading to Seville in Spain where the Dragonpit set is located.

Previously on "Game of Thrones" season 6, Theon and Yara (Gemma Whelan) waged a war with their Uncle Euron to conquer the Iron Islands. It was previously reported that the Greyjoy siblings will face their uncle at sea where Yara might be taken hostage.

Popsugar reports that Theon and Euron were seen fighting each other in Spain where the Iron Islands set is located. It seems that the two will catch up to each other back in their homeland, where their bloody brawl will finally decide who will rule the Iron Islands.

It is also possible that Theon is fighting Euron for the freedom of his sister, who has allegedly been taken hostage.

Meanwhile, a lot of "Game of Thrones" cast members were spotted at the Dragonpit set in Seville, Spain, while others are already on their way to film there.

According to the Winter is Coming fan news site, Jaime Lannister (Nikolaj Coster-Waldau) and Jorah Mormont (Iain Glen) were seen near the set of the stand-in Dragonpit at King's Landing. It seems that Jaime will be meeting the Mother of Dragons upon her arrival in Westeros, and Jorah will be by her side as he has always been.

The Instagram account got_updates also reports that Daenerys (Emilia Clarke), Missandei (Nathalie Emmanuel), Jon Snow (Kit Harington), and Davos Seaworth (Liam Cunningham) are all coming to Seville to shoot more scenes. It seems that all the action will be happening at the Dragonpit in King's Landing in "Game of Thrones" season 7.

And with Jon Snow and Daenerys meeting soon, will the former finally find out about his real family lineage?

"Game of Thrones" season 7 is expected to premiere in 2017.
