Adepta Sororitas

The Adepta Sororitas (also known as "the Sisterhood" or "Daughters of the Emperor") are an all-female subdivision of the religious organization known as the Ecclesiarchy or Ministorum. The Sisterhood's Orders Militant serve as the Ecclesiarchy's fighting arm, mercilessly rooting out corruption and heresy within humanity and every organization of the Adeptus Terra. The terms "Adepta Sororitas" and "Sisters of Battle" are commonly assumed to mean the same thing, but the latter title technically refers only to the Orders Militant - the military arm of the organization which is the largest and the best-known part of the Sororitas.
