Almost immediately after the modest wedding ceremony between Byleth and Dorothea was over, the battle against those who slither in the dark began in earnest. Dorothea chose not to take the field of battle with a weapon but rather to tend the household in her spouse's absence and provide emotional support to his effort to bring lasting peace to Fodlan. Many years after the war had ended, Dorothea's diary was uncovered, revealing the full extent of the happy life the couple shared. The love poems that they wrote to one another were published as a collection.
