Rosby

Long before the Seven Kingdoms existed, Rosby was already caught up in the rivalries among the lords of the Trident. King Benedict II Justman added these lands to his realm during a long reign, along with Duskendale and the mouth of the Blackwater Rush.

Generations later, Halleck Hoare, King of the Isles and the Rivers, pushed his borders out to Rosby and Duskendale once more, though the village remained little more than a stop along the road.

When Aegon Targaryen landed on the shores of the Blackwater Rush, Rosby offered no resistance. It surrendered to Rhaenys Targaryen and her dragon Meraxes, becoming part of the newly created Crownlands.

During the Dance of the Dragons, Ser Criston Cole seized Rosby as reprisal against its lord for backing Princess Rhaenyra Targaryen.

Later, as Rhaenyra fled King's Landing for Dragonstone, she and her retinue reached Rosby only to find its gates shut.

During the War of the Five Kings, much of the grain that fed King's Landing came from Rosby and neighboring Stokeworth.

Queen Cersei Lannister secretly sent Prince Tommen Baratheon to shelter at Rosby, to make things harder for Stannis Baratheon even if he took the capital. Tyrion Lannister learned of the plan and had the party intercepted; Ser Jacelyn Bywater caught the escort by surprise, and Lord Gyles Rosby, too ill to flee, ordered the castle gates opened without a fight.

Brienne of Tarth passed through Rosby while searching for Sansa Stark on the road to Duskendale, and crossed paths there with a band of Poor Fellows, the sparrows, headed for King's Landing.

Falyse Stokeworth and her husband meant to spend the night at the castle when Lord Gyles's young ward refused them entry, and Falyse feared the boy meant to claim the lands and title for himself.

When Lord Gyles died leaving no legitimate heir, Queen Cersei considered handing the castle and its lands to one of her own as reward for loyal service.

The Rosby inheritance reached the Small Council still unsettled. Grand Maester Pycelle reported that six separate claims had already been filed, but the Council chose to set the matter aside for more pressing business.
