After ending a couple of weeks ago, Game of Thrones' seventh season has left a huge series-shaped hole in all our lives. To fill the void, a number of fan theories surrounding the latest round of episodes are emerging on social media.
And it seems that one character in particular is at the centre of their fair share of hypotheses: the Night King. A few weeks ago, some already tried to link the character to Bran, claiming they could even turn out to be the same person.
Now, another theory has suggested that the White Walker chief may have more significant motivations for leading his army South than simply wanting to destroy his human enemies.
"I predict the Night King is going directly to the Gods Eye. Maybe he has been trying to reach the Gods Eye for centuries and man has always denied this passage. Therefore he has the mentality of removing all obstacles in his way.
The Isle of Faces, in the middle of the Gods Eye, is where the pact between man and the COTF happened. The rich history of the COTF can be found here. Leaf was also present during this pact and the moment Bran reached the cave. That means they potentially have eternal life?"
As a reminder, the God's Eye was first mentioned in the series in season one and refers to a lake in the Riverlands.
At the centre of this lake is the Isle of Faces, where the Children of the Forest (the creators of the White Walkers) and First Men agreed to a truce 10,000 years ago.
As Twerkmileyyy suggests, the Night King storyline could be turning into a classic 'creature returns to his creator' type of tale with one simple aim: to turn his army of White Walkers back into humans.
As the Redditor explains:
"Ultimately I think his end goal is to reach the Isles of Faces and use its magical properties to give life to his undead army. Eastwatch by the Sea is the closest part of the wall to the Gods Eye.
Harrenhall is on the northern shore of the Gods Eye. The writers have dropped hints about the Gods Eye for years and have always discussed the Riverlands with great detail. Also I think this is where Howland Reed makes his appearance in the show. He was the only cited character to be seen on the Isle of Faces, during the tournament of Harrenhall."
The mysterious Howland Reed mentioned is none other than Meera Reed's father, who helped Bran cross the Wall to meet the three-eyed raven. But he's also the only one to have survived the attack on the Tower of Joy led by Ned Stark to free his sister Lyanna.
The event was revealed to fans through one of Bran's visions, another of which also finally confirmed that Jon Snow is the son of Lyanna Stark and Rhaegar Targaryen.
Lord Howland Reed must surely be aware of Jon's true origins and will therefore perhaps help him to combat the White Walkers. His daughter, rejected by Bran and also well aware of the situation, is en route to Greywater Watch, the elusive seat of House Reed in the North.
As it goes, their castle is located in the Neck, a small marsh-filled region bordering the Trident, i.e. probably not all that far from the Gods Eye... If this is the case, it looks like the with the seventh season could have set up the foundations for some major future reunions between various key characters.
We'll have to wait for the eighth season of the show – expected to premiere in late 2018 or early 2019 – to see if the White Walkers really do want to return to human form or if they're just on a murderous rampage.
In the meantime, we're already fantasising about which other deceased characters could come back to life...
