Warhammer 40K — A Universe from the Mind of A Scribe

Games Workshop's dystopian future where humankind is ruled by the ‘Eternal Emperor’, a pysker who is kept eternally alive by the sacrifice of lesser pyskers. Humanity is kept under martial law, and vast armies are utilised to protect against many enemies, like Demons from the Warp, Eldar, Orks, Tyranids, Necrons, Tau and, inevitably, other humans.
