The Night King and the White Walker invasion may be the highlight of “Game of Thrones” Season 6. The cast members of the TV series talked about how significant the invasion is, but the people in Westeros are busy with their petty squabbles.

[Spoiler alert]

In an interview with IGN, Sophie Turner (Sansa Stark) described the impending invasion as a “big thing.” The actress pointed out that so far the TV series has mostly focused on the battles of the Houses, but the eventual war against the White Walkers is “unstoppable.” “It's more ominous than anything. It's looming, and you really get a sense that the end is nigh,” Turner said.

One character who may be the key to ensuring the defeat of the Night King and the White Walkers is Bran (Isaac Hempstead Wright). The actor said that his character has a huge responsibility, but he will be making “silly decisions” with his new found powers. Bran will have to learn quickly if he wants to be useful.

Liam Cunningham (Davos) said that while the Night King is coming in “Game of Thrones” Season 6, all the major characters are busy with their own “little squabbles.” Davos was seen talking about the coming danger in the trailer and the actor now confirms that his character was speaking to Lyanna Mormont.

Not only the people in Westeros, but the Faceless Men across the Narrow Sea are well aware of the danger. Tom Wlaschiha (Jaqen H’ghar) said that he was sure the Faceless Men know about the White Walkers and what is happening in Westeros.

The final battle between the humans and the White Walkers may not be fought in “Game of Thrones” Season 6. Iwan Rheon (Ramsay Bolton) said that his character will be fighting many battles, before taking on the White Walkers.
