“Game of Thrones” has brought viewers several bloody battle throughout the years — “Battle of the Bastards” in Season 6, the White Walker’s Season 5 attack on The Wall and more. The HBO original series may be gearing up for another face-off in Season 7, and this one appears to be more epic than any of the others.

Fans have spotted various members of the “Game of Thrones” cast on set in Spain, with photos providing major insight into what’s coming in Season 7. With so much information leaking, producers have tightened security, a move some speculate may be intended to keep a major scene under wraps.

Several months ago it was reported that “Game of Thrones” would be filming in various locations in Spain, including Basque Country and Seville. While in Seville, the network was said to have been using the Italica ruins, which some — including Vanity Fair writer Joanna Robinson and spoiler group Watchers on the Wall — speculate will be used as the Dragonpit.

In the books the Dragonpit is fighting arena dug into the ground, located high above King’s Landing. Cast sightings around Seville, Spain, have lead fans to believe that a number of important characters will come together at the pit for a battle royale. Watchers on the Wall theorizes that Daenerys (Emilia Clarke), Jon Snow (Kit Harington), Theon Greyjoy (Alfie Allen), Ser Davos (Liam Cunningham), Cersei Lannister (Lena Headey), Jaime Lannister (Nikolaj Coster-Waldau), Ser Gregor Clegane — also known as The Mountain (Hafþór Júlíus Björnsson), Euron Greyjoy (Pilou Asbæk) and more will gather at the site in the final scene of Season 7. What may ensue at the Dragonpit is expected to be the most brutal clash in “Game of Thrones” history — which is really saying something.

While this is likely to be one of the more action-packed moments of Season 7, there is plenty more to look forward to. Fan photos have revealed that after several seasons of anticipation, Daenerys and Jon — who are unaware of their relations — will finally come together. Before taking on the Dragonpit, the Mother of Dragons and Bastard of Winterfell will meet, hopefully joining forces. Fan photos, which hit the web Oct. 24, show the pair in what Spanish-language “Game of Thrones” spoiler site Los Siete Reinos believes it Dragonstone — an ancient city that the Targaryens once called home. The nature of their meeting remains unclear, but the pair were seen calmly chatting while looking out from a cliffside onto the water.

Other photos, snagged by Watchers on the Wall, show Daenerys and Jon bonding with her dragons. The site speculates that Jon was seen petting Rhaegal, the dragon she named after his father Rhaegar Targaryen. While it was difficult to tell how much of the moments photographed by fans was for “Game of Thrones” and how much was simply Harington and Clarke having fun with the dragon heads, many Thronies believe the sighting is a sign of confirmation of a long-standing theory about the dragons and their riders. The theory is born from a portion of George R.R. Martin’s “A Song of Ice and Fire” novels, which states that Daenerys’ dragon “has three heads.” Fans of the show believe the idea will be represented symbolically in Season 7 as the three Targaryen riders. The dragon wrangling trio is believe to be made up of Daenerys, Jon and Tyrion Lannister (Peter Dinklage).

There is currently no evidence to support claims that Tyrion is a Targaryen in the show. In the books, however, his character is said to have similar features to members of the family and is obsessed with dragons. It is also written that the Mad King had his way with Tyrion’s mother during his lifetime, which makes it entirely possible that he is Tyrion’s father rather than Tywin Lannister (Charles Dance). The last, and perhaps most pointed clue to Jon, Daenerys and Tyrion’s connection is that in the books the mothers of all three characters died during childbirth. While it may be mere coincidence, we and many other Thronies are hopeful it’s a sign of a deeper connection.

As for what else is in store for Season 7 of “Game of Thrones,” fans will have to cross their fingers for more spoilers or wait patiently until 2017.
