I'VE POSTED THIS MANY TIMES ON /GOT/ but I'll have to post it again.
Euron will be the Big Bad in the South, like how the White Walkers are the Big Bad in the North.
Jon and Daenerys will exhaust themselves in vanquishing the Night King, but then they will be soundly defeated by King Euron Greyjoy, the Iron King on the Iron Throne.
in the same fashion that William the Conqueror defeated Harold after the Norwegians distracted him
the final scene will be
>Euron as the final victor
>Jon Snow's head on a pike to his left
>Dany's head on a pike to his right
>Tyrion's skull used as a footstool, with three dragon skulls surrounding him
>Cersei, Sansa, and Melisandre on a leash as salt wives
>Sam as an enslaved Maester forced to write up works glorifying Euron and depicting the events of the series, titled "A Song of Ice and Fire"
BANK ON IT. SCREENCAP THIS. I KNOW D&D WILL WANT AN EDGELORD ENDING TO THEIR EDGELORD SHOW TO PISS OFF THE NORMIES
