Season 10
Millions have fled Westeros and are now following Jon Snow including many living defectors from Euron's armies, now officially known as Aegon Targaryen, true king of the 7 kingdoms, as he marches east to Asshai in search of an answer, a journey that will be filled with many dangers and challenges.
Dorne and a few small pockets such as Riverun remain the only living resistance in Westeros but they are holding them off for now.
Jon faced with so many refugees from Westeros has to find them a homeland and does so by conquering Meereen from Daario Naharis and the land around it, founding the nation of Targerar.
He is about to kill Daario and slaughter what remains of his army but Melisandre interferes and warns them they need allies in the war with the Night King.
With common folks settled, Jon can now continue his journey to Asshai with only those able to make the trip.
Along the way, Bran has a vision and warns Jon that something's not quite right. He is correct, Qyburn is missing and well ahead of everyone, recruits warlocks and attempts to destroy the Night King by sundering the land north of the Wall. Bran warns that if this spell is successful it could destroy not just the north but cause a devastating cataclysm throughout the world. It's now a race against time to complete the journey to Asshai and stop Qyburn.
Qyburn is stopped but his spell manages to weaken the Night King. His life is spared for now. Some White Walkers and wights die off on the spot, Euron is weakened as well while others like Dany regain free will.
Undead Dany betrays Euron and Euron is forced to flee north to regain his power. Dany helps Edmure Tully take King's Landing from the dead but betrays him in the end when he demands that she leave the city and take her undead "animals" with her. She kills him and crowns herself Queen of the Seven Kingdoms. Undead Jorah Mormont (who was not burned as Winterfell was lost in this revision) and undead Lyanna Mormont join her. King's Landing becomes populated by free willed undead now. Undead Greyworm is captain of the guard and undead Missandei an advisor.
Dorne reluctantly supports her claim as long as she helps them kill off the "bad" undead.
In one year she manages to retake everything south of the Twins.
Far to the north, Euron strangles a weakened Night King absorbing his power in the process and becoming the new Night King. His new mission in life now? Same as before probably. Get hammered as **** (as much as the living dead can), ***** some **** up and then **** the queen Daenerys. Some things never change.
