House Allyrion

Lords of Godsgrace on the Greenblood, a wealthy Dornish house whose heir wandered the world as a hedge knight before coming home to his inheritance.

The fuller tale

Godsgrace guards a crossing of the Greenblood, the great river down which the orphans of the Rhoyne pole their boats, and House Allyrion has grown rich on that traffic. The Lady Delonne rules there in the books, and her son Ser Ryon Allyrion is her heir.

The house's most colourful son, Ser Daemon Sand, is a bastard of Godsgrace raised alongside the prince's children and made a knight — a Dornish Sand who earned his spurs and his place at court, the sort of story Dorne tells about itself to explain why its bastards are not the shameful things they are counted elsewhere.
