WARNING: The following contains spoilers for the latest episode of Game of Thrones, "The Long Night," which aired Sunday on HBO.

"We have won the Great War. Now we will win the Last War."

After months, if not years of anticipation, Game of Thrones has delivered its biggest and most devastating battle yet. In "The Long Night," the dead fought the living, dragons scorched the earth, and fan-favorite heroes gave their lives in order to defeat the Night King and his army of White Walkers.

At the close of the episode, the fate of certain characters was left up in the air. But thanks to the preview for next Sunday's all-new episode, we now know that Danaerys' dragon Rhaegal officially survived the White Walker onslaught.

Jon and Danaerys both rode their respective dragons, Rhaegal and Drogon, into battle against the Night King and the undead Viserion in "The Long Night," the episode ended by confirming that Drogon was still alive -- but Rhaegal was nowhere to be seen.

In the promo for Game of Thrones' next episode, however, we see the dragon is alive and well. What's more, the preview also confirms that Jon Snow's direwolf Ghost survived the battle against the Wights as well.

But while the Night King may be defeated, that doesn't mean everyone who survived the battle is out of the woods just yet. The "Last War" is coming, and the battle for the Iron Throne will begin anew.
