(I do not own Warhammer 40k or RWBY, they belong to their respective owners) The Grey Knights are one of the most secretive chapters of the Imperium. They are known as the "Fist of The Emperor". This story follows a Grey Knight in the name of Rytsar. He has fought countless battles across the galaxy. Banishing daemons, burning heretics and slaughtering traitors. So what happens when one of the Grey Knights gets thrown towards the world of Remnant. Will it be Order? Or Chaos? Also, this is an alternate universe where there are no protagonist deaths or something.
