House Moore is a house of the Vale of Arryn, sworn to House Arryn of the Eyrie, blazoning three bronze spearheads within an embattled bronze border. No chronicle records their seat or their words. Ser Maladon Moore served in the Kingsguard of Maegor I Targaryen before he was beheaded for his part in Queen Ceryse Hightower's death, and Lady Perianne Moore, called Pretty Peri, was a companion of Princess Saera Targaryen hastily wed to Lord Jonah Mooton after a court scandal.
Ser Mandon Moore serves in Robert Baratheon's Kingsguard and survives the King's Landing riots after Myrcella's departure to Dorne. At the Battle of the Blackwater he is set to guard Tyrion Lannister, and instead turns his blade against him; Podrick Payne shoves Mandon into the Blackwater Rush, where the weight of his armor drags him under.
