Introduction: (this is NOT an official Warhammer 40k book, it's a custom faction made by a fan of Warhammer 40k, all credits for the universe goes to Games Workshop)a history of the great Corvun Nation, includes a new xeno species, democracy, and Grimdark version of USA (why not add USA to the 40k universe?)a fictional history book, i guess. It's a bit brutal, though so you are warned...
