Triston Massey was the Lord of Stonedance and the head of House Massey during the War of Conquest.
When Aegon the Conqueror prepared to begin his conquest of Westeros, he summoned his friends and bannermen to attend to him on Dragonstone, Lord Massey among them. Despite being sworn to House Durrandon of Storm's End, Triston had closer ties to House Targaryen.
After Aegon was crowned as King of All Westeros, he created the first small council and Lord Triston had the honor of becoming master of laws.
