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, Ingrid, whose wisdom and tenacity ensured that the people would prosper. Sylvain was ever loyal to his beloved wife. The couple had many children, and while not one of them bore a Crest, they were all equally and wholeheartedly loved.
