Soon after Byleth and Lorenz had celebrated their marriage in style, the battle against those who slither in the dark began in earnest. After fighting hard to bring true peace to Fodlan, Lorenz took over as head of House Gloucester, and he and his wife focused their efforts on restoring the territory. They had an active political and military life over the years, working together to overcome many hardships. After decades of dedicated service to the people, Lorenz grew weak and retired. Byleth followed suit, and they entrusted House Gloucester to their son. It is said that he was the spitting image of his father, right down to his signature red rose.
