And how would Mycella become queen if Arianne had wed her to Trystane?
'Dorne is large peninsula which makes up the southern-most part of Westeros, and is one constituent regions of the Seven Kingdoms. Its capital is Sunspear and the lords of the ruling House Martell still style themselves "Prince" and "Princess" in the Rhoynish fashion.'
