Meanwhile on the grimdark end of the space fantasy spectrum....

* My astropath may not claim that they're the closest thing most people will ever get to meeting the actual God-Emperor and act like she is a holy being that everyone should worship
** If she is technically correct about the first part, given that she has a shard of the emperor's very soul inside of her
*** "Hey girl, want to get it on with a literal shard of divinity" is not a good pickup line.
**** trying to convert Slaanesh to pure lesbianism to get rid of their cruelty is not a good plan.
*****especially when the Ecclesiarchy is always watchful for Slaaneshi heresy

* May not claim the God-Emperor's true gender is nonbinary and refer to them as Emperor/Empress interchangeably.
** the God-Emperor is not an androgynous being who decided to go with "Emperor of Mankind" for convenience.
*** "Emperoress of Humankind" just doesn't have the same ring to it.

* Khorne and his worshippers are not destroyed as if by holy power by hugging them and reciting lines from any of the following: My Little Pony, Steven Universe, Undertale, Naruto, Trigun, Pokemon....
** Nurgle is not destroyed by spraying hand sanitizer while chanting "wash your hands, brush your teeth, take a shower!" repeatedly
*** Tzeentch is not destroyed by presenting a football in front of him and talking about the latest sports.
