‘Game of Thrones’ Season 3 Teaser Warns of Never-Ending Night

First teaser trailer for the third season of "GoT" features no footage from the show, just a dire warning.

The latest "Game of Thrones" teaser reminds fans to remember March 31 — and that's about all it does.

Much like the first teaser poster for the third season of "Game of Thrones," the teaser trailer offers only one image: the date of the season three premiere. But at least the flickering graphic is accompanied by an ominous warning.

"The Great War is between death and life, ice and fire," says a mysterious, female voice. "If we lose, the night will never end."

Perhaps she's referring to the army of White Walkers preparing to cross over the Wall into the Seven Kingdoms at the end of last season. Unless the battling thrones put their differences aside and start working together, the characters may be in store for a very long and frightening night.
