Each season in “Game of Thrones” the special effects, the action is upped. From the now very rough cut scene it seems of the opening of Season 1, with the White Walkers killing some of the Night’s Watch rangers, to season 4’s Night’s King turns Craster’s last baby boy into a White Walker to last season’s epic “Hardhome” episode, fans know that they can expect each season to deliver a groundbreaking White Walker and Wight episode.

Sources close to the production of Season 6 tease a massive game-changing event by the White Walkers being worked on, and will be filmed by October. When pressed for details the source would only say, “If you think the special effects were magnificent in last season’s (5) eight episode, you had better prepare for utter shock coming up next year. Not only are the dragons going to be massive next season, but viewers are about to learn more about the mysterious creatures from the Lands of Always Winter.

So, will there be another battle? “I’m sworn to secrecy, but I can assure you, the scenes planned will break the Internet.”

Last season’s “Hardhome” saw Lord Commander Jon Snow headed North of The Wall to the mysterious Wildling sanctuary which immediately changed once Winter and the White Walkers arrived. The Night’s King essentially had the Wights and White Walkers kill over 100,000 Wildlings and then chillingly and calmly turn them into Wights, adding to the Army of the Dead. One had to know that there was no turning back the clock on this storyline, and Winter will eventually come in earnest across Westeros. The damage that was done in Hardhome is only a sampling of what comes once the White Walkers and their Army of dead men make it South of The Wall.
