On the surface, Sylvester is something of a twit, and not conspicuously brave. He's actually made of much sterner stuff than first impressions would suggest. He's well-educated, and has a very firm grasp on the workings of both the Mansion and the country at large.
Son of Willoughby Winston Sterling Eman and born of Dorothea Anne Mundivagant, Slyvester is the oldest child in the family. He has three brothers (Ace, Mortimer, and Rufus) and two sisters (Lil and Lenore).
