Adeptus Sororitas



The Adepta Sororitas, also known as the Sisters of Battle and formerly as the Daughters of the Emperor, are an all-female division of the Imperial Cult's ecclesiastical Adepta known as the Ecclesiarchy or, more formally, as the Adeptus Ministorum. The Sisterhood's Orders Militant serve as the Ecclesiarchy's military arm, mercilessly rooting out corruption and heresy within humanity and every organization of the Adeptus Terra.

There is naturally some overlap between the duties of the Sisterhood and the Imperial Inquisition; for this reason, although the Inquisition and the Sisterhood remain entirely separate organizations, the Orders Militant of the Adepta Sororitas also act as the Chamber Militant of the Inquisition's Ordo Hereticus.

The Adepta Sororitas and the Sisters of Battle are commonly regarded as the same organization, but the latter title technically refers only to the Orders Militant of the Adepta Sororitas, the best-known part of the organization. The Sisterhood serves as the Ministorum's only official military force because the Decree Passive laid down by the reformist Ecclesiarch Sebastian Thor held that in the wake of the Age of Apostasy's Reign of Blood in the 36th Millennium, the Ecclesiarchy cannot maintain any "men under arms."

This command was supposed to limit the power of the Ecclesiarchy by preventing it from maintaining the massive armies of the faithful Frateris Templar it once used to abuse its power from the 32nd to the 36th Millennia. However, the Adeptus Ministorum has been able to circumvent this decree by using the all-female military force of the Sisterhood's Orders Militant.

In When the Cold Breeze Blows Away, there is also naturally some overlap between the duties of the Sisterhood and the Grand Alliance; for this reason, although the Grand Alliance and the Sisterhood remain entirely separate organizations.
