House Locke

House Locke of Oldcastle is a noble house from Oldcastle in the north.

Their banner is two bronze keys crossed on a white pale on purple. Their words do not appear in the text.

History
The Lockes ruled as First Men kings after the Long Night, but they were eventually reduced to vassals by the Kings of Winter from House Stark.

After the extinction of House Greystark, the Flints held the Wolf's Den for a century and the Lockes for almost two centuries.

Ser Mallador Locke joins the great ranging of the Night's Watch commanded by Lord Commander Jeor Mormont. He is in charge of the baggage train and the packhorses.

Lord Ondrew Locke excuses himself from attending the harvest feast at Winterfell because he is too old to dare the journey. He sends his best wishes to Robb Stark.

The acting Hand of the King, Tyrion Lannister, plans to exchange Donnel and Lord Medger Cerwyn for Tion Frey, but the negotiations fail. Held at Harrenhal, Donnel is freed by Roose Bolton when he takes the castle.

A Storm of Swords
When the Watch receives news of the approach of the wildlings to the Fist of the First Men, Mallador supports retreating back to the Wall. However, he is not among the survivors of the expedition who return to Castle Black.

While going to the Twins to attend Lord Edmure Tully's wedding, the Lockes are caught on the wrong side of the Trident. They suffer heavy losses when attacked by Gregor Clegane in the fighting at the fords of the Trident. Donnel Locke is slain at the Red Wedding; Catelyn Stark sees him being taken by crossbow bolts fired by the Freys. Outside the Twins, Bolton men forces the soldiers of House Locke to surrender. Only twelve of their men are killed in the massacre.

Lord Ondrew Locke later pledges fealty to House Bolton, along with several other northern houses.

When Lord Roose Bolton takes Theon Greyjoy to Barrow Hall, amongst the banners they see are old Lord Ondrew Locke's crossed keys. Ondrew follows Roose to Winterfell for the wedding of Ramsay to "Arya Stark". However, Wyman believes the Lockes of Oldcastle will take their lead not from House Bolton, but from House Manderly, after what happened at the Red Wedding.
