HBO has released a teaser for season two of its acclaimed fantasy series “Game of Thrones.” The clip is light on action, but does feature a voiceover from Lord Stannis Baratheon–King Robert’s brother—promising a medieval ass-whopping to those keeping him from his rightful seat on the throne.

“Game of Thrones” season two is set to premiere in April. The show will consist of 10 episodes spanning the length of the book “A Clash of Kings,” the second volume in author  George R.R. Martin’s popular book series “A Song of Ice and Fire.”
