Adepta Sororitas, known as the Sisters of Battle, are elite female units of the Imperium, raised from childhood to absolute faith in the Emperor. They are the military arm of the Ecclesiarchy, the church of the Imperium, and their fanatical devotion is as deadly as their bolters and flamers.

Their combat doctrine is based on miracles, holy fury, and unwavering purity. In battle, they rely on Acts of Faith, allowing them to perform extraordinary feats – from ignoring wounds to executing actions that others could not achieve.

The most famous orders are the Order of Our Martyred Lady, Order of the Bloody Rose, and Order of the Valorous Heart. Each order has its own fighting style, heraldry, and sacred relics. Beyond the battle sisters, the organization also includes Hospitallers, Dialogous, and Repentia – women seeking redemption through combat.
