Throughout a seven seasons journey, 'Game of Thrones' has put in place a spectacular and complex production, the first of its kind that has reached such a high standard. As any successful narrative plot, the villain has some unique characteristics too, a set of skills and tools that make the possibility of Evil to prevail against Good more likely to happen. The Night King is not a common enemy and due to its unique feature, to annihilate him would take an effort far from the comfort zone. Tus, it's easy to predict that some of the key characters that survived until now are likely to die one way or another.
The intriguing part is how the quiet deadly threat has been growing bigger and bigger while sheltering its true force in the icy field behind the Wall.
Too busy with their meaningless goals, the livings turned a blind eye on the real threat
Like a nightmare that returns one night after another, the Army of the Dead hasn't had much to deliver until recently. The Season 7 finale saw hordes of dead soldiers marching right through a freshly pierced wall bringing in the ultimate threat to the entire Realm.
The overwhelming feeling must be brutal and given the political climate of Westeros, the Night King can expand his kingdom all over it.
Except for Jon Snow and a few others who had to deal with the Night King and its army before, the people in Westeros are walking into a dark chamber without knowing that it has been turned into a slaughterhouse.
To put it differently, the Night King orchestrates an invasion that seems to be a simple reminder of how futile life truly is. Cersei Lannister is the definition of a person who has lost any sense of what's really matter. She seems ready to betray the fragile non-aggression pact with Jon Snow and Daenerys Targaryen and to pursue her megalomaniac dreams of controlling the Realm.
The Night King's identity is not that important
The Night King has been a fascinating character since he emerged as a villain in 'Game of Thrones'. His identity remains a undeciphered mistery but that might not be that important. What really matters is that he seems to have come in Westeros to bring punishment, death and despair for a world that has crossed the decency red line a long time ago.
Let's not forget that some of the most beloved characters like Daenerys Targaryen, Jon Snow, Jaime Lannister or Arya Stark they all have their individual bag filled up with sins and crimes. It's a decadent world, to say the least, and the Night King fits perfectly in it.
