Council of Apostles
The Council was at one point usurped by Zaragram II, who proclaimed himself the divine manifestation of God. After Zaragram's death, the Council did its best to erase all history of him and for a short time became extremely powerful. This power eventually led to the Moral Reforms.
It was dissolved during the Moral Reforms, where much of its powers were transferred to the Emperor and the Privy Council. Many of its records and artifacts were preserved by the Order of St. Tetrimon.
