Sansa secretly promises to marry Littlefinger in exchange for military support. John secretly secures the support of the Greywaters (Reeds). John and Sansa take Winterfell without a fight after the Umbers (and Manderlys) betray the Boltons with the three armies gathered outside of Winterfell (Ramsay is fed to the dogs as his father warned him would happen because of his cruelty). We discover Littlefinger had the Umbers in his pocket and Rickon was another pawn for his schemes. The Arryns return to the Eyrie. Sansa unites the north. John, the Reeds, and the Stark army ride south to the Neck.
The tension between the Faith, the Lannisters, and the Tyrells continues. Arya shows up in Kings Landing and assassinates Cersei and The Mountain. Jamie thinks the Faith were behind it. The Tyrells abandon Kings Landing and return home. Jamie abandons the north to march on Kings Landing.
Edmure Tully reveals the Blackfish was not killed and retakes Riverrun. The northern army and the Tully army take The Twins. Also possible that Arya continues her murder spree and takes out Walder Frey (and maybe Littlefinger?).
Daenerys destroys the Masters' fleet and the bulk of their military power with the help of her dragons (and maybe the Ironborn, can't figure out Euron's part as he's so vastly different than in the books). As a result, Daenerys unites the Free Cities and secures their future. She also has the loyalty of the Dothraki and likely at least one faction of the Ironborn. In the books, Daenerys is supposed to go East into Asshai and I think the introduction of the red priestesses means she probably will before eventually heading to Dragonstone.
Daenerys offers the Houses of Westeros the right to retain titles and lands if they swear fealty (like her ancestors did). The Tyrells offer allegiance. Daenerys claims Dorne through Rhaegar's marriage to Elia. Dorne is effectively leaderless, Varys lays the groundwork for alliance, and the Sand Snakes refuse to honor the claim of "any man" which is a convenient foreshadowing for Daenerys.
This leaves Westeros divided as follows: Northern Alliance under Sansa and John; Daenerys poised for conquest in the South; the Lannisters battling the Faith in the middle.
Samwell discovers the Maesters are trying to suppress/eliminate magic from the world. They had almost done so by killing all the dragons last time around. He runs from Oldtown (what he does best) and tells John what the maesters have done/are planning. This reveals the Seven to be a vast conspiracy and maybe reveals the Faith's part in destroying House Targaryen (as revenge for taking away the Faith's powers). .
I think Jamie dies at some point during this or is forced to take the Black and Tyrion inherits the Lannister lands, uniting the South under Daenerys. "The dragon has three riders" means John unites the North, Daenerys unites the South, and Tyrion brings in the rest. Conquest by diplomacy this time (mostly).
John Snow is revealed to be Rhaegar and Lyanna's child: John Targaryen. The great houses of Stark and Targaryen are joined in alliance. Daenarys learns about the Maester conspiracy and takes Kings Landing and Oldtown and destroys/subverts the Faith. The "conquest" of Westeros is completed in time for a final showdown between The Lord of Light and The Others.
Bran Stark is revealed to have been popping in and out of history for a thousand years as "Bran the Builder" and has influenced just enough to delay the Others for long enough for everybody else to unite against them.
