Ending Quote
"Petra returned to her homeland of Brigid, and inherited the throne from her grandfather. As ruler, she declared independence from Fódlan, and renegotiated Brigid's diplomatic ties to that nation on more equal terms. At every step along the way, she was accompanied by her wife Dorothea, who had left Fódlan behind to support her. Dorothea used the connections she had made in her time at the opera to her benefit, and even worked reluctantly with the Fódlan nobility for Petra's sake. The people of Brigid were skeptical of her at first, but warmed up to her over time. It is said that she became the person whom Petra loved the most."
