Well we all know the Ironborn's prayer: "what is dead may never die, but rises again harder and stronger", and that seems nice and...WAIT doesn't this seem ominous to you? up past the wall the dead are rising again, and they seem alot more difficult to kill so if you ask me that sounds like harder and stronger.

Hang on to your tinfoil hats boys and girls, we're going for a ride, first; Some history

The Iron Islands were settled by the first men and as far as I can tell came across no Weirwoods/Children of the Forests or simply just killed them in the war that followed. This allowed those prickly Ironborn to keep their Cephalopod God (heh, that rhymes) where the soft surrendering mainland first men gave truce to the Children and adopted their gods.

So enough with history and let's get onto the good stuff:

From my joyful wanderings around /r/asoiaf, I have read several theories concerning the Others as minions or allies of the Children, and I am willing to accept it for now becuase what I'm saying will (hopefully) blow your mind, the prayer to the all mighty Cthulhu Drowned God is not some meaningless sentiment to their Kraken, but a warning lost in the annuls of time. The inhabitants of the Iron Islands would be mostly pure first men, as you're not going to have many wandering bands of Andals settling in the inhospitable stumps of rocks these hardy folks call home; and any integration there may be from salt wives or true love would be swamped by the culture of a very secluded and insular community.

They never surrendered to the first men or their icy allies; they are constantly reminded of the threats of the walking dead, and they themselves try to emulate the destruction and strength of the Wights by rising again from drowning. Why else would Harren the Black decide to build the largest most defendable castle alongside Gods Eye lake, home to the last community of Children of the Forest south of the Wall, Coincidence?

So what I'm saying is don't rule out Theon or Asha; or even Damphair, the chanter of the words; or Rodrik Harlaw, the reader, who knows what histories he's read. They'll all play some part to come.

I mean afterall, all Ice turns to water, and the Ironmen know about water.
