Adepta Sororitas

Adepta Sororitas


The Adepta Sororitas are an all-female division of the Ecclesiarchy – the official Church of the Imperial Cult. While there are many different arms of the Adepta Sororitas, the most famous are the Chambers Militant, more commonly known as the Sisters of Battle.

The Sisters of Battle form the military arm of the Ecclesiarchy. They are tasked with merciless rooting out corruption and heresy within the Imperium, as well as protecting pilgrim routes, important shrines and forming the vanguard in Wars of Faith. Each Battle Sister is an elite warrior armed not only with power armour and bolter, but also an unflinching and absolute devotion to the God-Emperor of Mankind.

  • Acts of Faith:  For the Sisters of Battle, their faith is as much a weapon as the bolter and chainsword. Unyielding and true zealots, the strength of their belief allows them to make the Emperor’s Will manifest in the form of miracles.
  • The Orders Militant: The forces of the Sisters of Battle are split between the six major Orders across the galaxy. These are The Orders of Our Martyred Lady, The Sacred Rose, The Ebon Chalice, The Argent Shroud, The Valorous Heart and The Bloody Rose. Within these major orders are many more minor orders that are, in theory at least, answerable to the leaders of their parent order.
  • Witch Hunters: The Sisters of Battle maintain close ties with the Ordo Hereticus, each organisation dedicated to the rooting out and destruction of heresy. As such, they are often the go-to choice when Inquisitors of this Ordo need soldiers.
