The Greyjoys of Pyke claim descent from the Grey King of the Age of Heroes. Legend says the Grey King ruled not only the western isles but the sea itself, and took a mermaid to wife.
For thousands of years, raiders from the Iron Islands—called “ironmen” by those they plundered—were the terrors of the seas, sailing as far as the Port of Ibben and the Summer Isles. They prided themselves on their fierceness in battle and their sacred freedoms. Each island had its own “salt king” and “rock king.” The High King of the Isles was chosen from among their number, until King Urron made the throne hereditary by murdering the other kings when they assembled for a choosing. Urron’s own line was extinguished a thousand years later when the Andals swept over the islands. The Greyjoys, like other island lords, intermarried with the conquerers.
The Iron Kings extended their rule far beyond the isles themselves, carving kingdoms out of the mainland with fire and sword. King Qhored could truthfully boast that his writ ran “wherever men can smell salt water or hear the crash of waves.” In later centuries, Qhored’s descendents lost the Arbor, Oldtown, Bear Island, and much of the western shore. Still, come the Wars of Conquest, King Herren the Black ruled all the lands between the mountains, from the Neck to the Blackwater Rush. When Harren and his sons perished in the fall of Harrenhal, Aegon Targaryen granted the riverlands to House Tully, and allowed the surviving lords of the Iron Islands to revive their ancient custom and chose who should have the primacy among them. They chose Lord Vickon Greyjoy of Pyke.
The Greyjoy sigil is a golden Kraken upon a black field. Their words are We Do Not Sow.
