House Caron of Nightsong is one of the principal noble houses in the stormlands, sworn to Storm's End. They rule from Nightsong and hold the title Lord of the Marches, although they do not hold dominion over other marcher lords in the Dornish Marches.
Their blazon is a field of black nightingales on yellow. Their words are No Song so Sweet.
The Carons date back to the Age of Heroes, and they are a family known for creating warriors and singers. They claim their nightingale sigil has been in 1,000 battles. Maester Yandel states Nightsong has been sworn to Storm's End since time immemorial, but also that the Kingdom of the Reachonce included western marches from Horn Hill to Nightsong. The Carons and Swanns both claim to be the oldest of the marcher lords.
Ser Arlan and Dunk served Lord Caron and Lord Dondarrion when they fought the Vulture King in the Red Mountains. Lord Pearse Caron was one of the outstanding participants in the tourney at Ashford Meadow. He was a harper, singer and knight of renown, and had his personal arms emblazoned with a silver harp. Pearse chose Leo Tyrell as his opponent at Ashford. The match was even, and Pearse managed to shatter Leo's shield, but in the end he yielded. Lord Caron ignored Dunk when he was asked for help in the trial of seven.
In 287 AC, Brienne of Tarth was promised to the younger son of Lord Bryen Caron, a shy boy with a mole above his lip, but two years later a chill caused his death, also taking the lives of Lord Caron, his wife and their daughters. This left young Bryce Caron as Lord of the Marches.
