HBO has gone to extreme lengths to keep "Game of Thrones" a secret after several episodes from the fifth season were leaked online before its official broadcast. However, the network has once again suffered a major leak after plot details of the upcoming Season 7 made its way to the Internet.

A Reddit user named awayforthelads shared some major spoilers from next season on the internet community, including major character deaths and plot twists. Normally, fans would shrug off information like that as fan-made theory, but "Game of Thrones" fansite Watchers on the Wall also started confirming the detailed spoilers using sources and on-set photos. The Reddit user's account was also mysteriously removed.

If the leak is anything to go by, fans will see Queen Cersei, Daenerys Targaryen and Jon Snow join forces to fight against the White Walkers in the upcoming season. Snow refuses to bend the knee for the Mother of Dragons, but agrees to give up his 'King of the North' title if she teams up with him against the humanoid ice creatures.

What happens next could be considered as one of the most epic scenes in "Game of Thrones" history. Cersei, Tyrion Lannister, Snow, Targaryen, Varys, Missandei, Qyburn, Euron Greyjoy, The Mountain and The Hound assemble in the Dragon Pit in King's Landing, where Snow has brought an undead wight as proof of the impending threat against the Seven Kingdoms.

Cersei agrees to help but goes back on her word when the time comes and instead sends her men north, in an attempt to make the most of the ongoing battle between the White Walkers and her weakened opponents. Disgusted by Cersei's move, Jamie Lannister rides north to join the fight against the Night's King.

Snow enlisted the likes of Tormund Giantsbane, Beric Dondarrion, The Hound, Thoros of Myr and Jorah in order to catch the wight, according to Daily Mail. However, they are attacked and surrounded by the White Walkers on an island encircled by a frozen lake.

The ensuing battle results in the deaths of Thoros, who is killed by a wight polar bear, as well as Snow's uncle Benjen as he tries to protect his nephew. The group is rescued by Targaryen and her three dragons, but one of her dragons, Viserion, is killed by the Night's King in the process. He later brings the dragon back to life as his own mount and uses the blue-fire breathing dragon to bring down The Wall.

If the leak is genuine, there is no doubt that the upcoming season will be an epic one for the fans. "Game of Thrones" Season 7 is expected to premiere in Summer 2017.
