The author's composition is a bit complicated, adding the Moon Project
In the dark universe of the 41st millennium, the human empire is like a candle in the wind, struggling on the edge of survival. The minions of the Four Chaos Gods of the Warp ravage the star realm, Nurgle's plague corrupts the world, Tzeentch's conspiracy weaves traps, Khorne's fury tears apart defenses, and Slaanesh's temptation corrodes the soul.
The Emperor sits on the Golden Throne and uses his own psychic powers to keep the empire running, but it is difficult to prevent the internal decay - rebellions, heretics and aliens are everywhere. The flesh and blood of the Astra Militarum forms a defense line, and the power armor of the Space Marines shines with the last hope.
Every battle is a gamble of life and death, and every persistence is a resistance to chaos. Human beings use faith as a shield and swords as spears to find light in the endless darkness, using blood and sacrifice to defend the last possibility of the survival of the species.
Where should mankind go from here?
