Just not as hope-filled as a Warhammer 40K meme, alas.
But, yeah, 'tis our contemporary world:
Fine, some hope:
Dante, Chapter Master of the heroic Blood Angels chapter, Warden of the Imperium Nihilus and the oldest surviving Space Marine not honorably interred in a Dreadnought, doing what he does best: striking back at the encroaching darkness.
Seriously, Guy Haley's Dante and The Devastation of Baal are two of the best 40k books, period. Not a flawless Mary Sue, Dante is just a man turned into a superhuman who carries the heavy burdens that come with leadership.
Even victory can be almost too much to bear.
