She is such a badass. I played 52 games of Warhammer 40k in my life so far, and Celestine has been in 51 of those, just because one game was a 500 points one.
After hearing this, I can understand why the chemistry between the Black Templars and the Adeptus Sororitas is extraordinary. Together, they are literally a sentient train of slaughter.
After finding this, it has become a part of my morning routine to listen to Saint Celestine before I take on the day. May the Emperor guide me on my path. The Emperor protects, brothers and sisters.
I feel your faith brothers, but it must be "stronger! You are sons of Dorn, the warriors of Sigismund, you call yourselves champions of The Emperor! He calls upon you now to lend me your wraith, lend me your hate, lend me your fire, Praise Him!"
