The Ecclesiarchal Palace is situated on Terra. The Palace is actually a vast urban complex covering most of Terra's southernmost continent. It is the headquarters of the Ministorum, its spiritual and material home. The Ecclesiarch lives in a heavily armed and armoured fortress. The Convent Sanctorum of the Adepta Sororitas is also based within the Palace. The commander of the Convent is the Abbess of the Adepta Sororitas, who is the overall spiritual leader of the Sisterhood. She is assisted by a battle leader with the rank of Prioress.
