The Lord of the Tides
The Lord of the Tides is the hereditary title of the head of House Velaryon, one of the oldest noble houses in Westeros. The Velaryons are of pure Valyrian blood, with silver-gold hair and purple eyes, and their power base is the island of Driftmark in the Narrow Sea. Their sigil is a seahorse, and their words are "The Old, the True, the Brave." Before the Doom of Valyria, the Velaryons were a powerful seafaring house, and after Aegon's Conquest they often served as masters of ships on the small council, commanding the royal fleet. Their seat is the castle of High Tide on Driftmark, though by the time of the books the family's fortunes have waned considerably.
History and Decline
During the reign of the Targaryens, the Velaryons were among their most loyal supporters, providing brides, lords admiral, and hands of the king. However, after Robert's Rebellion, the family's close ties to the fallen dynasty left them diminished. By the start of the War of the Five Kings, the current Lord of the Tides is Monford Velaryon, who initially declares for Stannis Baratheon. Monford is killed at the Battle of the Blackwater, and his young son Monterys becomes the nominal lord, but the family's power is shattered. The Velaryon fleet is destroyed or captured, and their lands are ravaged. The title thus becomes largely ceremonial, a relic of a bygone era.
Narrative Significance
The Lord of the Tides appears only briefly in the narrative, primarily through the actions of Monford Velaryon, who is one of Stannis's principal bannermen. His death at the Blackwater underscores the devastating cost of the war for the old Targaryen loyalists. The title also carries symbolic weight: it represents the ancient, pure Valyrian bloodline that is now nearly extinct, and the fading of the old order in the face of the Lannister-Tyrell ascendancy. The Velaryons' decline mirrors that of the Targaryens themselves, and their reduced circumstances serve as a quiet reminder of the price of loyalty to a lost cause.
