His Righteous Symphony (Warhammer 40k)

By the design of the God-Emperor of Mankind, The Imperium was born: a bulwark to unite humanity and assert its rightful place of dominance in the galaxy. Among His legions, none are more devoted than the Adepta Sororitas. This sisterhood enacts His will across the stars by guiding the faithful and vanquishing the faithless.

After a great calamity fractured His Imperium, the Sisterhood of the Righteous Symphony must safeguard the world of Incheo until it can reunite with the rest of mankind. Duty and loyalty shall protect their minds against corruption. Bolter, Flamer, and Melta shall slay the witch, the mutant, and the heretic. By the grace of Saint Arabella, the dark will not take this world without a fight.
