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.

Summary
“Hands in the air!”
Morgan had Sam on the floor in seconds, knee in his back. Jenkins shoved Dean down hard enough that the carpet burned his cheek.
“Sam and Dean Winchester, you are under arrest.” Hotch began.
“Where’s Hendrickson?” Dean asked, the words bitten out from where his chest was pressed to the floor.
Hotch held his stare, steady and cold. “You thought you had trouble when it was just Hendrickson. You’ve got an entire unit now, Dean.”
OR
The BAU finally get their claws into the Winchesters. They aren't going to let go without a fight.
