Older than the Iron Throne itself, the Warrior's Sons drew their ranks from highborn men willing to trade an inheritance for a hairshirt and a sword blessed at the Starry Sept; celibate, landless, and answerable to the High Septon alone, the order had stood for the Faith since long before Aegon's dragons crossed the narrow sea. It was King Aenys I's weak rule — and, more precisely, his blessing of his own children's marriage in the Valyrian fashion — that goaded the Swords into rising against a crown they judged had broken faith first, riding out to enforce the Faith's own writ as though it outranked the Iron Throne's, which for a time it very nearly did.
Maegor the Cruel met the order's defiance with a bounty of a golden dragon for every Warrior's Son's head, and hunted the Swords to near-extinction across his reign; this chronicle repeats the archmaesters' account of his private trophies from that hunting with the same distaste those archmaesters recorded it, and no more certainty than they allowed themselves.
The handful of Warrior's Sons who outlived Maegor laid down their blades under Jaehaerys I's settlement of 48 AC — the Iron Throne's promise to defend the Faith, bought at the price of the Faith's own soldiers. No individual Swords commander survives in the record by name; the office simply ended when the men holding it did. Whether the order's recent counterpart among the Poor Fellows portends any revival of the Swords too is a question this chronicle notes has been raised, and answers no further than that.
