The series is based on novels by George RR Martin in a series called A Song of Ice and Fire.
The teaser shows a dragon and direwolf overtaken by ice on one side of a table while a lion gets consumed by fire at the opposite end. This will be the last season of the show.
The 40-second teaser tweeted out with the words "Fire and ice" hints at what the fans can expect in the right and final season of the show. The ice takes over most of the towns in the North, before eventually making it to Winterfell. But the story of Game of Thrones has always been about fire and ice, be it White Walkers and Targaryens, or aunts and nephews who may unite the kingdom by being in accidentally incestuous relationships. If the result is dragonglass, it's worth noting that's one of the few ways White Walkers can be killed. This also denotes the critical importance of Daenerys' and Jon's alliance, as only their combination can save Westeros from eternal darkness. When the two forces combine, the results are explosive.
