High King of Dorne
Houses of the Greenblood
The title was also claimed by a ruler seated on a great wooden motte-and-bailey castle on the south bank of the Greenblood near Lemonwood. This king was chosen by election from a dozen noble houses settled along the river or its eastern shores. These included Houses Briar, Brook, Brownhill, Holt, Lake, Shell, and Wade. This powerful river realm ended when a disputed election led to warfare. After a generation of war, three houses were extinct and the realm had splintered into a dozen petty kingdoms.
