My favorite piece of 40k lore is how the Orks are actually the most technologically advanced race because the reason they can build spaceships out of like sheet metal is bc they have instinctive knowledge on how to manipulate the laws of physics and during the Grand Crusade the Emperor that attacked a world that showed what Ork technology was like if they settled down and got their shit together because it had force field that blunted the Imperiums planet-killing weapons and when they launched a ground assault which resulted in them getting slaughtered because the Ork weapons just melted power armor so the Emperor had to just scramble the minds of the Orks and was only able to implode the planet by messing with their energy generators because it turned out these Orks figured out how to like trap bits of the Warp in plasma fields and harness them for energy which even by stupid 40k standards is supposed be totally impossible through mechanical means
WH40K is a particularly British apocalypse where it’s World War Forever and the dumb cheerful hooligans painted with woad are Our Boys
