The Grey Knights are the legendary Chapter 666 - and although nominally a Chapter of the Astartes, they are in the Chamber Militant of the Inquisition. The Grey Knights hold a unique honour among the chapters of the Adeptus Astartes - in over ten thousand years of service, not a single one of their number has ever defected to Chaos. This is a skin I based off another skin that I saw someone have. I hope you enjoy it!
