As Margrave Gautier, Sylvain devoted his life to improving relations with the people of Sreng. Under his leadership, nobles were persuaded that Relics and Crests were not necessary as they'd previously thought. Though he went down in history as an extraordinary lord, he could not have done so without the constant support and counsel of his wife, Mercedes, whose wisdom and guidance brought prosperity to the people. The couple built a loving home life, surrounded by happy children, and when Sylvain at last passed away, he was succeeded by his oldest child, who bore no Crest.
