Hagia is an Imperial Agri-World located in the Sabbat Worlds Sector of the Segmentum Pacificus that was the birthplace of Saint Sabbat and now serves as the burial place for her remains, thus transforming Hagia into an important Shrine World of the Ecclesiarchy as well. The capital city of the world is the Holy Doctrinopolis.
