The trailer shows almost all the main characters of the series. TV channel HBO has released a teaser trailer for the sixth season of "Game of Thrones", which is based on the book by George R. Martin "The Song of Ice and Fire".
The sixth season of the fantasy drama television series “Game of Thrones” was ordered by HBO on April 8, 2014, together with the fifth season, and is scheduled to premiere on April 24, 2016.
In contrast to the previous seasons, it largely consists of original content not found in George R. R. Martin's “The Song of Ice and Fire” series, but also adapts the material from the upcoming sixth novel in the series, “The Winds of Winter”, as well as some content from the fourth and fifth novels, “A Feast for Crows” and “A Dance with Dragons”.
Beyond the wall, Bran Stark has been training with the Three-Eyed Raven, having last appeared in the season four finale episode "The Children". According to the interview conducted with Isaac Hempstead Wright about Bran's plot line in season six, the training largely expands his previous ability to see into the past and future, and allows him more control to piece things together. He also discovers his role in the wars to come.
