HBO recently dropped two new video trailers for the upcoming seventh season of its highly popular television series, "Game of Thrones." The trailers, called "The Great War is Here" and "Winter is Here," both revealed a slew of brand new details regarding the upcoming season through different scenes and dialogue that basically showcases just how epic the new episodes will be. Most, if not all of the upcoming episodes, will likely be filled with different battles as all of the planning and scheming from the previous seasons have now come to its climax.

Jon Snow and the White Walkers

Ned's bastard child, who has been revealed to actually be the son of Lady Lyanna Stark and Rhaegar Targaryen, the Prince of Dragonstone, has been quite busy gathering forces to fight against the army of the Night King north of the wall. The new trailers have revealed that he will have a lot of very powerful allies in the coming battle, including the seemingly immortal Beric Dondarrion. Dondarrion is also seen wielding his infamous flaming sword and bringing with him a new ally in the form of the Sandor Clegane, a.k.a. the Hound. Several scenes within the trailers have also confirmed that Snow will have the support of Jon and Tormund Giantsbane and their Wildling army.

Naval Battle

All the events that have befallen Theon Greyjoy have now led to the highly anticipated faceoff between him and Euron Greyjoy. The trailers have hinted that Euron may be seeking to form an alliance with Queen Cersei, which will basically place him against Theon and Yara as their massive fleets face each other in naval warfare.

Cersei will likely accept Euron's help given that he is one of the only remaining armies that are willing to ally themselves with her at this point.

Casterly Rock

House Lannister's ancestral stronghold, Casterly Rock, has been revealed in the trailers to be invaded by Daenerys Targaryen and her Dothraki army. Grey Worm and a small band of unsullied are even shown infiltrating the stronghold and opening up its gates for their main army.

Jaime Lannister along with Bronn is also shown leading the charge in the defense of their home, but they will likely be unsuccessful in their task. Daenerys is also shown riding her dragon, Drogon, on top of her Dothraki horde, charging towards Lannister forces.

"Game of Thrones" season 7 is scheduled to premiere its brand new episodes on July 16 on HBO. Unlike the previous seasons, which had ten episodes each, the upcoming new season will only have seven episodes.
