The motto of the house is, “Set Down Our Deeds.” The only members of the house to appear or be mentioned are old, sickly, and failing Lord Penrose and his son Ser Cortnay Penrose. Ser Cortnay was castellan of Storm’s End for some years, and had grown to love the young Edric Storm, King Robert’s bastard who had been made Lord Renly’s ward.
Lord Penrose secretly spoke with Ser Davos Seaworth about supporting Stannis’s bid for the throne, but rejected him although he was more courteous than most.
After Renly’s death, Ser Cortnay refused to give up Storm’s End to King Stannis, in part out of fear for Stannis’s intentions towards Edric. He challenged Stannis or one of his champions to single combat to decide the fate of the castle, but was refused. Ser Cortnay was soon killed by a shadow-creature made by the red priestess, Melisandre. The garrison at Storm’s End, led by young Lord Meadows, quickly opened the gates to King Stannis.
