Existence, from beginning to now (Reworked) by JohnMandrage

Summary
This is basically a creation myth for Hololive I posted a few years ago, shortly after council's debut. I corrected a few writing mistakes I made back then and now repost this. Have fun.
In the beginning the Universe was a point without past and future. In this primordial place existed two beings. Then a third joined them, a human crone with greyed blond hair and an object blessed by these two beings. She came to tell them of grand concepts, of depth and length and of time marching inexorably from the past towards the future…

Omake: Rogue Trader Visha AU by JohnMandrage for l4oftheWEST

Summary
This is a Omake story for L4oftheWest set in an AU of his story "The Saga of the Runt", and I would recommend reading his story until chapter chapter 36 before starting to read this, beyond that the title says it all.
This work started as a one shot and I'm currently continuing it. The story starts shortly after Tanya meet Perturabo and before she meets Mortarion.
Featuring:
Arc I, the Founding of a Mechanicum rival: Chapter 1-7 Mainly politics and a void battle, this arc was when I added the “Canon typical violence” tag, because someone got his head crushed. My grammar and spelling in these early chapters is also a bit rough, but it get's better in later arcs.Arc II, the Gala: Chapter 8-19 Mainly romance and Viktoriya interacting with Tanya's family, this arc also features the only NSFW scene in the story.
Arc III, the Persean Sector: Chapter 20-? A return to politics and action.
It is with regret that I have to announce that I will cease my work on Rogue Trader Visha for the foreseeable future. It might very well be that I pick up this project next month or never at all, I simply don't know. As such I wish to inform you all of this, it just feels right to openly announce this.

The Divine Marriage by 8uggestionAmplifie6

Summary
“What?”
Roboute is confused—more than he has been since, arguably, the Battle at Calth. He almost wonders if he is hallucinating; it has been nearly half a year since he last slept, and he has just returned from a decade-long campaign in Imperium Nihilus.
Before him stands Decimus Androdinus Felix—his son and tetrarch—who has lost his usual composure. Instead, he looks vaguely disturbed as he repeats himself, "Nearby Chapters have reported to me—there is a peculiar... rumor spreading that you and the Emperor... are married."
_____
AKA, that time when the collective Imperium decided that the Emperor and Guilliman are married!

Summary
When the "hero" of the Imperium of Man wakes up in the body of a child in a world of magic, he quickly realizes one thing — this is not the universe he knows.
There is no Imperium.
No Guard.
No chain of command.Reincarnation?
Of course. Why not.A new world, magic, monsters, and noble politics.
A twin brother — a perverse genius obsessed with the teacher's underwear.
Father — a former adventurer.
Mother — saintly patience.And somewhere in the background, someone who suspiciously resembles a chaos god is trying to influence the future.
If this is punishment for my previous life, it is exceptionally creative.

Summary
The elven mage from the Mythical Era eyes' narrowed. “You have quite the interesting look on your face,” she said. Pheles hummed. Her smile became slightly wider. “Tell me, what went through your mind when you first saw me?”
Pheles considered the question. She did not need long.
“I fell in love with you at first sight.”
“...”
“...”
Serie stared.
Pheles stared back.
Somewhere beyond the door, someone dropped something.
“...”
“Did you hit your head?”
—
Magic is meant to make the impossible possible. If you cannot imagine something, it cannot be. That is the most fundamental and simplest understanding of Magic. To Pheles, it's simple. You wish for power? Imagine yourself as a demon.
This is a story about an Elven Mage who despises demons, and a human who imagines herself as one.

Summary
She recalls this scene. Himmel and the villager spare a demon who betrays their kindness. Who dooms the village in fire.
This body she inhabits belongs to that villain. She can’t see them, but she knows they're there: two pointed horns, curving from her head.
