Summary
A collection of snippits and one shots I have written for Marathon. Most of these are just silly short stories or fun prompts from Tumblr.
For fifty years Durandal's ship, The Rozinante, flew through the galaxy. Examining, analyzing, and discarding data as he chose. There is the pesky Pfhor Empire to contend with during this time, as well as a growing universe of aliens and problems to address.
At least both Durandal and his Battleroids could safely say that life is never boring!

Summary
They say the sky is full of diamonds, but who chisels those gems out of the muddy earth? Who shines them? Cuts them into the perfect shape? And when the diamonds finally take their place among the stars, was it really worth it?
It may take a while before an A.I. has the answer.

Summary
A genius from the Dark Age of Technology gets teleported to 30k and fixes all sorts of shenanigans through the power of SCIENCE. Lots of techno gibberish. Not only science fiction but also fictional science. You have been warned.
I don't know if this counts as AU but there are some canon-divergent background settings and timeline alterations. There is some romance but it's mostly not about romance.- Language:

Summary
Title 2: I Wanted the Wolf King, but I Got the Warmaster Before the Fall.
Transmigrating into the most despair-inducing Underhive wastes of the 41st Millennium, Kaelen, a mere mortal, thought his days were numbered.
When his cheat system finally activated, he prayed for one thing: Just give me Leman Russ. I need the Wolf King to survive!
[Ding! System error. Target locked: Davin. Salvaging soul...] Instead of the loyalist Wolf, a dying giant crashed before him, his soul teetering on the edge of Chaos corruption. It was the Warmaster himself. Horus Lupercal.
Staring at the tragic, uncorrupted demigod covered in scars, Kaelen went completely silent.
"Horus," Kaelen sighed, pushing up his goggles. "Your father is a corpse on a golden toilet, your brothers have all gone insane, and the Imperium is a rotten hell-hole."
Horus: "...?"
No divine bloodlines. No genetic enhancements. Just a mortal commander armed with future knowledge, a glitchy system, and the most powerful Primarch in history serving as his loyal sword. If the galaxy is broken, they will carve a bloody path from the Underhive to Holy Terra to fix it.

Summary
Boba Fett is settling in as the leader of a syndicate on Tatooine, crushing his enemies, freeing their slaves, and generally trying to build a new reputation for himself. He'd like to see more of that Mando he helped. Djarin was useful around the Palace and good company. The kind (ever so rare) you could trust to watch your back. But Kryze got her claws into Djarin and they're off reclaiming Mandalore and Boba doesn't expect to see Djarin any time soon.
Boba really doesn't expect to see Djarin in his throne room with a group of kids.
And that first visit is only the beginning.

Summary
This is an Alternate Universe that came about due to a question asked by a 40k theorist who posed the question on how things would have changed in Roboute Guilliman had found Angron before the Emperor, the following is the result of me thinking about this for far too long. This will be written as a history with occasional scenes that I had in my mind.
