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 organisation of the Adeptus Terra.
