But why was the Night King created in the first place?
And what does he want, exactly?
EW askedGoTshowrunners David Benioff and Dan Weiss what inspired them to add the character to their HBO hit series.

The Night King in ‘Game of Thrones’.HBO
Weve seen what the White Walkers do, weve seen how they perpetuate themselves and created the wights.
If youre going backwards, well, they made these things … so what made them?
Theyre the result of people, or beings, with motivations we can understand.
But what does the Night King actually want?
I dont think of him as evil, I think of him as Death, Benioff said.
And thats what he wants for all of us.
Its why he was created and thats what hes after.
Benioff notes that another common question they get about the character is why doesnt the Night King ever speak.
Whats he going to say?
Anything the Night King says diminishes him.
