Sylvester is the 23rd and current Earl of E.
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 Windston Sterling Eman and born of Dorothea Anne Mundivagent, Slyvester is the oldest child in the family. He has three brothers (Ace, Mortimer and Rufus) and two sisters (Lil and Lenore).
