Thomas Birchills is the Benedictine abbot of Chester Abbey. Father Thomas is a principled man, enduring the administrative burdens of his office despite the time it takes from prayer and contemplation. He often frowns upon those who might bend the rules, such as Sir Henry of the Temple. Thomas is concerned with the potential of the Godstone. He is well known in the community, and friends with Prior Simon and Prioress Alice de Pierrepont.
