War Against the Great Clean One

You are a guardsman living in the 40k universe. (Already off to a bad start). You get deployed to a planet to fight a chaos incursion of Nurgle. Unfortunately the Black Library author made a typo so now it’s an incursion by Gurgle, the 5th Chaos God of Cleanliness, who you might know for his greater demon, the Great Clean One, and the Demon Primark of the 11nth Legion, Mr Clean. I was gonna make this Teen but apparently AIdungeon found The Great Unclean One so horribly Cursed that it figured the Image demanded Mature least it traumatize the youths. (Specifically it called it “Psychological Distressing”)
