The Stepstones War was a private campaign waged from 106 AC by Corlys Velaryon and Daemon Targaryen against the Triarchy’s control of the Stepstones. It joined Corlys’s maritime power to Daemon’s military ambition, produced a brief conquest and a self-proclaimed kingdom, and then turned back into a wider conflict when the Triarchy invaded again with Dorne as its ally.

The islands and the stakes

The Stepstones are a chain of rocky islands between Dorne and the Disputed Lands of Essos. Their own resources were limited, but their position gave them command of important sea lanes leading to and from the Narrow Sea. For centuries, outlaws, exiles, wreckers, and pirates had used the islands as a base, preying on merchant shipping. The danger had generally been treated as a nuisance rather than a threat to the balance of power.

That balance changed when Lys, Myr, and Tyrosh set aside their longstanding rivalries to fight Volantis. After defeating the Volantenes at the Battle of the Borderland, the three cities formed an alliance governed by thirty-three magisters. Known in Westeros as the Triarchy, or the Kingdom of the Three Daughters, this new power turned west after Volantis made peace and withdrew from the Disputed Lands. Its combined armies and fleets swept across the Stepstones under the command of Craghas Drahar, a Myrish prince admiral. His treatment of captured pirates, left on the wet sands to drown with the rising tide, earned him the name Craghas Crabfeeder.

The Triarchy’s conquest was initially welcomed by Westerosi lords: it appeared to replace disorder with authority, and a toll on ships seemed an acceptable price for safer passage. But the tolls rose repeatedly until they became ruinous. Merchants who had once paid sought ways around the Triarchy’s galleys, while its commanders competed, as their critics saw it, to extract more from passing vessels. The Lyseni were particularly hated for taking women, girls, and boys from ships and selling them into sexual slavery. The growing cost and abuse of Triarchy rule made its apparent restoration of order harder to defend.

Corlys and Daemon take up arms

Corlys Velaryon, Lord of the Tides, had particular reason to oppose the Triarchy. His fleets had made him one of the wealthiest and most powerful men in the Seven Kingdoms, and the tolls and seizures threatened the commerce on which that position rested. He found an eager partner in Daemon Targaryen, who saw the war as a chance to win wealth and glory.

The two men made their plans at High Tide on Driftmark, away from King Viserys’s wedding celebrations in 106 AC. Their roles reflected the forces each could bring: Corlys commanded the fleet, while Daemon led the army. They were greatly outnumbered by the Triarchy, but Daemon also brought Caraxes, the dragon known as the Blood Wyrm. Sea power, a land force, and a dragon thus formed the campaign’s central combination, set against an opponent with superior numbers and control of the islands.

Daemon had little difficulty gathering an army of landless adventurers and second sons. The fighting began in 106 AC, and during the first two years he won a number of victories. In 108 AC he met Craghas Crabfeeder and killed him single-handed, taking his head with Dark Sister. The death of the Triarchy’s commander marked the campaign’s clearest personal triumph, though it did not end the contest for the Stepstones.

A brief kingdom and renewed war

King Viserys supported Daemon’s effort with regular infusions of gold. By 109 AC, Daemon and his force of sellswords and cutthroats controlled all but two of the islands, while Corlys’s fleet held firm control of the waters between them. Their gains gave the campaign a striking, if fragile, political outcome: Daemon declared himself king of the Stepstones and the Narrow Sea, and Corlys placed a crown upon his head.

The declaration did not make the new kingdom secure. The remaining islands and the Triarchy’s ability to return meant that victory on land and control of the surrounding waters had not settled who would rule the chain. In the following year, the Triarchy sent a fresh invasion force under Racallio Ryndoon, a Tyroshi captain. Dorne joined the war in alliance with the Triarchy, and the fighting resumed. The renewed invasion reversed the sense of easy triumph attached to Daemon’s coronation: the claim to kingship was made at the high point of the campaign, not after a lasting settlement.

The war beside the royal court

The conflict unfolded alongside the peaceful, celebratory life of Viserys’s court. The king was content to let Daemon wage war, regarding his brother’s absence as a way to keep him out of trouble. King’s Landing continued to host feasts, balls, and tourneys, and the birth of new royal children drew public attention even while the Stepstones remained contested.

That contrast also placed the war beside an unsettled question of succession. Rhaenyra Targaryen continued to sit at the foot of the Iron Throne and attend small council meetings, and Viserys maintained her as his acknowledged heir despite having sons with Queen Alicent. The Stepstones campaign did not resolve that dispute, but its political setting matters: Daemon’s pursuit of a separate crown took place while the king’s own court presented an image of continuity and celebration. In the account of the war, the islands are both a strategic prize and the setting for Daemon’s temporary elevation, while the Triarchy’s return makes clear how quickly that elevation could be challenged.
