Good guys lose the Battle of Winterfell. Nearly everyone dies. Jon, Dany, Arya, Sansa, Jaime, Tyrion, and Bran live (Bran only to later reveal that Night King was a victim whose people were slaughtered and whose humanity was stolen and who has suffered immortal human exile and madness for thousands of years and seeks vengeance and death, in that order). Good guys flee to Iron Islands as The Dead move south. At last, Tyrion and Cersei collaborate to destroy (most of) The Dead with wildfire. Cersei finally does one good, noble, human thingĀ in agreeing to work together. Jon faces Night King in single combat amid wildfire and dragon flames. He’s mortally wounded. At the last moment, just as he’s about to die, Jaime Kingslayer kills Night King with a stab from behind. Good guys win. Arya kills Cersei anyway, because: her list. Jaime and Tyrion have mixed feelings. Heartbroken Dany establishes the Two Kingdoms (and eventually Republics), the North, in honor of Jon, to be Queened by Sansa, and the South, also known as the Dragonlands (including Essos/Slaver’s Bay). Dany retreats to Dragonstone where she dies giving birth to Jon’s son, name of Aegon, who will be raised by Regent Tyrion and Varys. Her last dragon, Drogon, grows weak and dies. And like The Bear and The Maiden Fair and the Dance of Dragons, the Song of Ice and Fire is the myth ballad told for thousands of years of how magic disappeared from the world and Westeros transitioned into modernity. Maester Sam writes the book.
See guys, good storytelling isn’t that hard.
