A year after Byleth was appointed to succeed Rhea as the new archbishop, she announced her marriage to Dedue, who had resigned his position as the king's vassal. Their wedding ceremony, brightly colored with all of the most beautiful flowers from Duscur, set the tone for their happy life together. Dedue served as an intermediary between Faerghus and the church and-alongside the archbishop-committed to improve relations with foreign nations as part of the rebuilding effort. In their later years, they retired to the Duscur Peninsula where they spent the remainder of their lives gardening in peace and quiet.
