Petra took Ashe with her to her homeland of Brigid, where she inherited the throne from her grandfather. With Ashe's guidance, she established an order of knights, and used that order to declare independence from Fodlan and renegotiate diplomatic ties on more equal terms. Over years of work reforming diplomatic and military policy together, Petra and Ashe fell in love and eventually were married. The people of Brigid warmly embraced the union. It is said that the name of the knightly order, the Blue Sun, was born of their mutual love of swimming in the sea.
