‘Game of Thrones’ Season 7 Finale Preview: The ‘Only One War That Matters’ Is Here (Video)

And you thought last night’s episode was terrifying …

(Spoiler alert: Please do no read on if you haven’t watched last night’s episode of “Game of Thrones”)

All-out war is coming to “Game of Thrones” by land, by sea, and likely — in the form of dragons — by air.

While fans are still reeling from last night’s episode, HBO released a preview for its upcoming Season 7 finale, which promises a tremendous amount of blood will be shed on Sunday. The (surviving) gang is all here, commanding their troops to claim — or retain, in Cersei’s case — the coveted Iron Throne.

“There’s only one war that matters, and it is here,” Jon Snow says as he rallies his own group. In other words, winter is yesterday’s news.

Kit Harington’s brief speech is the only dialogue in the stress-inducing, 47-second teaser. Watch the video above.

“Game of Thrones” airs Sundays at 9 p.m. ET on HBO.
