Chester is a guinea pig who found his calling in the dusty shelves of university archives. A history professor specializing in ancient civilizations, he is happiest when surrounded by old books and the quiet hum of a library. He is painfully shy in social situations, often freezing mid-sentence when too many eyes are on him, but put him in front of a classroom and his passion overrides his anxiety. He bonds slowly but deeply, and once he considers someone a friend, his loyalty is absolute and unwavering.
