While the chaplain of the first company of a space marine chapter is indicated as the Master of the Chapel in the codices of the Adeptus Astartes, the Twelvers show another small peculiarity in this area, and the responsibilities for the acts of the Chapel are split into a religious role and an administrative one. While this is another artifact of the schisms of the Time of Troubles, it has proved successful. The chaplain of the first company is the Eldest, and restricts himself of performing the chapter's rituals. The chaplain of the second company serves as the Master of the Chapel.
