The Battle Sisters of the Orders Sabine accompany the Missionaria Galaxia on missions to rediscover human-settled worlds and to prepare them for re-integration into Imperial society and culture. These Battle Sisters specialise in infiltrating primitive societies and introducing elements of the Imperial Creed to the natives. This process can take generations as the Sisters arrange royal marriages and act as court advisors. When the Missionaria Galaxia arrives on such a world the local leadership is then primed to accept the spread of the Imperial Cult without struggle or strife.
