Woody: Mole, the brand new preacher at the Church. The animals of the forest have never actually had a preacher before, and are slightly off about what exactly he does.
Riley: Mouse, liturgist (reader). When the critters decided they wanted to have a church, Riley offered his services to read The Book during mass (being the only one able to read at the time).
Burgher: Beaver, deacon. Pretty much has his hand in every aspect of the church, from taking care of the garden to ringing the bells.
Warren: Snake, parisher. A troubled soul, struggling to fight his genetic inclinations to consume his peers.
