The upcoming season of "Game of Thrones" on HBO will be different. Stars Nikolaj Coster-Waldau, who plays Jamie Lannister, and Kit Harington, who plays Jon Snow, are in agreement that fans will have to prepare themselves because season 7 will unfold at a faster pace.

Coster-Waldau told Entertainment Weekly he was shocked after reading the scripts. He described being "lulled into a different pace," while working on "Game of Thrones" season 7. He noted that storylines that usually unfolded for several episodes take just one episode this time.

Kit Harington also said the same thing and cautioned the new season will not be what viewers are used to.

The accelerated pace, however, will probably be a good thing because it will make the show even more exciting.

The Night King takes center stage

"Game of Thrones" season 7 will not only be faster but it will also have shorter episodes than usual. From the previous 10 episodes, the upcoming show will only be seven short episodes. Showrunner Dan Weiss said they needed to build up the pace because war is looming in this Westeros story. The game and power-grabbing are almost done.

With the new season release nearing, HBO came out with another teaser featuring The Night King, the leader of the White Walkers. Viewers expect this will be the season Jon Snow and the rest of the protagonists will come head to head with this enigma.

The White Walkers are the common enemy every kingdom in Westeros has to fear.

The Night King first appeared in Bran's vision in season 4 and then he briefly showed his face again in season 5 during an attack at Hardhome, which Jon Snow foiled.

In season 6, The Night King went after Bran, who learned the eerie leader very first man who became a White Walker as a curse from Leaf, the leader of the Children of the Forest.

Ghost's death

Meanwhile, fans of "Game of Thrones" were alerted to the sad news that the real-life wolf that played Jon Snow's canine companion has died.

George RR Martin tweeted that the animal cared for by the Wild Spirit Wolf Sanctuary "passed away this week."

Ghost on "Game of Thrones" is one of only two remaining dire wolves in the story. Each Stark children, including Ned Stark's illegitimate son, Jon Snow, adopted them as pets and four has since died in the course of the story. Nymeria, Arya Stark's dire wolf, went missing during the first season of the series and fans are certain it will resurface in the show.

Ghost, like his master, was different from his pack. The animal had red eyes and albino fur. While the dog that inspired him in real life is dead, Ghost on the show is still very much alive in the upcoming season.
