Hey guys, I have been toying around with this theory in my head for a while and I want to know what you think. I don't think there is a lot of evidence to it but I can't get it out of my head.

I think the white walkers are actually all Stark ancestors - lead by the Night's King who I believe is Brandon the Builder... (Winter is Coming, The Winds of Winter).

I think they have had to go into hiding for 1000s of years until man forgot about the power of dragon glass following the Night's King defeat.

I think they will likely use the horn to free Ice Dragons suspended in the wall (winds of winter), and have a quick stop over in the Winterfell crypts to raise a few kin. I also think the original reason for the wall was not to protect he south from the north, but actually to protect the north form the south.

This leaves the remainder of the plot to evolve into some sort of three way free for all. The Starks/white walkers/ice dragons vs Daenerys and fire dragons vs Jon Snow the half cast backed by TLOL

Feasible?
