At Comic Con Experience in Brazil, HBO released an "official tease" of Game of Thrones' final season.
The mysterious clip doesn't reveal much, but does show both sheets of ice and stormy flames colliding in Westeros and overtaking statues of a wolf, dragon and lion.
The website Insider points out that the clip is "a nice nod to the show's source material," George R.R. Martin's A Song of Ice and Fire series. The final season, Game of Thrones' eighth, premieres in April.
