'Game of Thrones': Season 7 finale titled 'The Dragon and the Wolf'

Aug. 23 (UPI) -- The final episode of Game of Thrones Season 7 will be titled "The Dragon and the Wolf."

HBO announced the title and confirmed a runtime for the highly-anticipated episode Tuesday.

"'There's only one war that matters and it is here.' Preview the #GoTS7 finale, 'The Dragon and the Wolf,' airing Sunday at 9PM on @HBO," the network wrote alongside a trailer for the episode on Twitter.

Entertainment Weekly reported the episode will have a runtime of 79 minutes and 43 seconds. The episode will be the longest in the show's history, beating last week's episode, "Beyond the Wall," which ran 70 minutes.

"The Dragon and the Wolf" seems to tease big things to come for Daenerys Targaryen (Emilia Clarke) and Jon Snow (Kit Harington), whose houses' sigils are a dragon and a wolf, respectively. The pair shared a tender moment in Sunday's episode following Jon's escape from beyond the wall.

The title may also hint at Jon's secret heritage. The Season 6 finale confirmed he is the son of Ned Stark's sister, Lyanna Stark, although his father hasn't been explicitly confirmed. Jon himself still believes he is Ned Stark's bastard son.

The Game of Thrones Season 7 finale will air Sunday, Aug. 27.
