Game of Thrones’ folklore is certainly a lengthy one, and fans of the show have turned to past theories to see if they can shed light on upcoming episodes.
One depicts the story of the Last Hero, a legend of the First Men who fought the wights during the last time winter arrived.
Legends of the north said that when the White Walkers invaded previously during the Long Night, one brave hero stood out among many.
The so-called “Last Hero” risked his life to look for the children of the forest, since they were the only ones to have “dragonsteel” blades which can kill a wight with ease.
Last Hero folklore has been discussed in the HBO series, with Old Nan (Margaret John) recounting the tale to Bran Stark (Isaac Hempstead Wright).
No one knows what happened to the Last Hero following his courageous victory during the Long Night.
Some fans believe that Bran could be linked to the legendary character, following his similar journey throughout the fantasy.
The youngest Stark has also been to the children of the forest, as well as experienced visions of the running into the Night King (Vladimir Furdik).
However, others believe the Last Hero to be directly linked to Azor Ahai – the prince that was promised.
That separate theory states a legendary hero wielding a fiery sword called Lightbringer will defeat darkness.
God R’hllor is thought to have sent the currently unknown figure to bring peace to the land.
Fans commonly believe Jon Snow (Kit Harington) to be the prophesied hero.
However, if the Last Hero and Azor Ahai are the same being, it could mean a last minute twist which declares Bran Stark as the one chosen by the mythical God.
Meanwhile, another wild theory has taken the internet by storm, suggesting that Cersei Lannister (Lena Headey) is actually the Night Queen in waiting.
Fans believe that she will be murdered by her brother, Jamie (Nikolaj Coster-Waldau) in tragic scenes.
However, a shocking twist will see her resurrected by the Night King, just in time for battle with Jon.
Game of Thrones will return to Sky Atlantic in 2019.
