Watch a very short 'Game of Thrones' teaser trailer

An unidentified woman's voice narrates "Game of Throne's" first season three teaser trailer which, at only 15 seconds long, manages to give nothing away but the premiere date -- March 31, 2013.

"The great war is between death and life, ice and fire. If we lose, the night will never end," the voiceover says.

Though it does sound like Melisandra (prone to enigmatic riddles about opposing forces), most fans seem to think the voice belongs to Laura Pradelska, who plays Quaithe, the masked Asshai priestess from the Shadow Lands. Others think the devout R'hllor worshipper, Selyse Baratheon, played by Tara Fitzgerald, set to make her first appearance next season.
