Sisters of Battle
The Sisters of Battle are the Eccllesiarchy's (The Imperium's religious branch) fighting arm. They are the ultimate religious zealots. They spread the word of their Lord and Saviour, the Beneficient Emperor. They are quite militant with their crusade and spread the word with highly advanced weaponry and armour, zealously pursuing Holy Wars and sending the galaxies heretics to hell, whether it be aliens or humans who refuse to accept "the truth"...
