A Divergence at the Eleventh Hour

Summary:

The Emperor of Mankind originally made twenty Primarchs, who were taken and scattered by the Gods of the Warp. Of the twenty, two were doomed to failures that resulted in their removal from all records.
Later, the Pantheon would show various individuals how the Primarchs were scattered.
However, they didn't account for the fact that in quantum physics, observation can change a result. Whether by deliberate interference, or by the nature of Chaos, one of the Primarchs doomed to be lost was sent to a different world to what they planned, creating a new timeline, and a new fate for the galaxy.

I was inspired to write this after reading "Legacy of the Red Angel" by Thought_Processing.
I don't own Warhammer 40k or the Horus Heresy, but my take on the XI primarch and their legion are my own.
This isn't quite going to be a Fix-It, there will still be a Heresy, but with some different Primarchs on each side, and a slightly more hopeful ending. More towards GrimBright than GrimDark - everything is horrible, but a glimmer of hope remains.

Chapter 1: Prologue: Scattered

Chapter Text

In a hidden lab beneath the Himalazian mountain range on Terra, the next stage of a great plan was nearing completion. In a set of twenty gestation pods protected by Gellar Fields far stronger than any seen in the future, a set of near-demigod warrior embryos near the point at which they will be ready to be born. The architect of the plan and of the embryos is away, finalising the structure of the empire he is building – too far distant to intervene.

Outside of the scientists, working to refine lesser versions of the twenty, there are several sets of eyes watching the pods. First is the occupant of the sixteenth pod but from the future, being shown his origins. Second, a group of warriors seeking the truth behind the stars. Third, a group of four beings worshipped as gods, who granted the architect the power to make the embryos, who have put a plan to reclaim what the architect promised them.

Unnoticed by all of the observers, except for the four gods, a woman steps quietly into the room. To the scientists, her presence is unremarkable, if they notice her at all. The woman helped make the twenty children in the pods, providing her own DNA for the architect to combine with his own, and now she fears for the fate of her children at the hands of their father. Unknown to the woman, her fears were manipulated by the four gods, to make her take the actions she has planned.

 

At the appointed time, the truth-seekers are convinced to cut the power to the Gellar Fields, allowing the mother to open a rift in the lab, causing the twenty pods to be scattered by the raging tides of the Sea of Souls. As soon as the rift is opened, the architect becomes aware of the mother's betrayal, though he is too slow to react. The four gods have already stolen the twenty children, and decided where to place them, so that in the future they will grow to turn from their father's plan.

Unfortunately for their plans, they have allowed too many to observe their scheme. And, as the scientists of the second and third millennium once knew, the act of observation changes the results on a quantum level. Two of the pods, marked three and five, divert from their planned course, each coming to rest on the planet intended for the other. In the moment's distraction caused by this switch, something else changes, unknown to the four until they sense the divergence in the timeline. Something caused pod eleven to shift slightly from the intended path, changing the fate of it's occupant. In that one moment, the one who should have been named Malibron comes to rest on a world that should never have been his, changing the fates of himself and his brothers forever.

Notes:

The name Malibron came from a Pre-Heresy campaign ran by Laurie Goulding, with some flavour text written by Graham McNeill.
My XI won't be called that because he landed on a different world, but I thought it would be nice to make reference to it.

I've only read about fifteen of the Horus Heresy books, so a lot of what I write in this fic will come from the Warhammer 40k wiki and Lexicanum.
