In the dark days of the late 41st Millennium, in the days of ceaseless war and numberless enemies that would see Mankind enslaved or wiped from existence, the Chapter Masters of the Space Marines are warriors without peer, standing resolute when others would waver, advancing without trepidation when other men flee and wisely withdrawing when only a fool would futilely fight on when the odds are stacked against them. By his example of true heroism and superlative command does a Master of the Space Marines awaken great deeds in lesser men, inspiring not only the Astartes under his command, but those mortal men and women whom they fight side-by-side with.
