Hopefully this is how it ends…
All that foreshadowing about ‘All Men Must Die’ … Men will die, and this is my gender-bend fantasy of A song of fire and ice ending…
Sansa - Queen on the Iron Throne. Not in the the North but The Queen.
Margery, Arianne, Myrcella - The Queen’s Small Council. Maybe Margery is the Hand, Maybe Arianne.
Arya - Lady Commander of The Queensguard.
Brienne, Mya, and older Sand Snakes - The Queensguard.
And Asha can be Mistress of Ships maybe.
The Mormont Sisters and Alys Karstark inherit The North - Rule as Ladies of Winterfel.
Val rules as Lady of the Free Folk - there is no wall. She is an ally to Sansa. But not a kneeler. She’s also de-facto Commander of the Nights Watch.
Dany sacrificed herself in the War of Winter to save the world and is the 'Last Hero' / Princess that was Promised / Azor Aahai - She is worshipped as a Goddess throughout Westeros and Essos - The Mother on Earth, Myshaa, The Last Dragon.
Mel helped Dany and sacrificed herself as well. She is lauded as high priestess.
