The Sisters of Battle, or Adepta Sororitas, are the militant arm of the Ecclesiarchy in the Warhammer 40,000 universe. Known for their unwavering faith in the God-Emperor, they are elite, power-armored warriors dedicated to purging heresy, xenos, and chaos. Their strength comes not just from their advanced weaponry but from their Acts of Faith, miraculous abilities believed to be fueled by their pure devotion. The Sisters are often deployed in the most dangerous warzones, where they serve as both warriors and symbols of Imperial piety, inspiring the faithful while striking terror into the hearts of their enemies.
