"The ironborn shall be waves ... Not the great and lordly, but the simple folk, tillers of the soil and fishers of the sea. The captains and the kings raised Euron up, but the common folk shall tear him down.
I shall go to Great Wyk, to Harlaw, to Orkmont, to Pyke itself. In every town and village shall my words
be heard. No godless man may sit the Seastone
Chair."—Aeron Greyjoy
