The teasers give quick glimpses of Sansa, Tyrion, Arya, Cersei and others, interspersed with footage from old seasons. The trailers are being released to those who subscribe to The Sight, which mimics the experience of having Greensight (the ability to see past, present and future). Multiple versions of each teaser are also being released with slight changes.
