(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. But i will be using homebrew stuff as well, i will give you a link to my youtube channel for extra lore drops in the community tab https://www.youtube.com/@The_Corvus_Republic) 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
