House Yronwood of Yronwood holds the second seat of Dorne, and they have never quite let the Martells forget it. The Yronwoods were Kings of the Stony Dornish in the eastern marches for thousands of years before Nymeria came, and they fought her landing more fiercely than any other house. The Bloodroyal still has the older blood of Dorne in his veins, and the Martells keep that fact in mind even now.
Lord Anders Yronwood styles himself Warden of the Stone Way and Bloodroyal, the latter title an inheritance from kings who ruled before any Martell ever sat a chair higher than his.
