(General POV)
Location the Materium/Realspace: Milky Way Galax, Solas System: Forgeworld Principal; Mars
The Cult Mechanicum is thriving even in the eradiated world of Mars, long have these people left Terra, and started establishing their domain, and what is known as a Forgeworld.
A term the Mechanicum, established to describe their ownership of a world, and Mars being as sacred as Terra for the Mechanicum, this grand forgeworld, it serves to be a multi-purpose factorium, a combination of a holy temple and factory, were these men and women work endlessly to craft weaponry, machinery, and start the process of replacing flesh with machine...
For the machine and cybernetic, was pure and more resilient to the irritated forces of their world.
Hymns sung, and sacred oils are use to appease the machine, as these centuries their develop into deeper fanatism, and through their collective devotion, and idolism over the machine, and the Machine Spirit inside all machines and technology, was empowering someone.
Feeding it knowledge, divinity, and this entity starting to develope deeper complex thoughts and emotions.
Like it's rivals before, this dark entity, deep in the Warp, was starting to spread it's grasp on the minds of these humans...
Increasing their ingenuity, wonder, and desires to compress technology, aside that he'd didn't need to have deeper grasp on these souls...they'll willingly walk into the path of his dark thrall.
All while it grows stronger, smarter, emotional, complexity, desire, and much more, as these mortal are granting life to the lifeless, emotion to the programmed, and understanding to the logic-bound.
These machine spirits, will be it's greatest servents, as these red robed, technophiles, mutilated themselves to become more machine, pleasing the true God of Machine...meanwhile in the Immaterium he grew...
Location the Warhammer 40k World-The Immaterium, Deep in the Forge of Souls, the Throne of the Original Heretek-z
The Arkefine...one of the names that this entity, has awakened in his still growing mind as his daemons the Husk Exos and Servants of the Silent Ones, protecting his throne and cocoon, along with making the Forge of Souls work properly.
Efficiency it is the Arkefine's main desire for his neverborn servents, as these mortal of the Cult Mechanicum were foolishly establishing his foothold in all machines and technology in Realspace.
Every passing moment his power and influence grows, while his infernal legion was miniscule in comparison with his...siblings.
But the Arkefine, plans to use his connection to the Forge of Souls, as leverage against it stronger, and older rivals.
Maintaining them away, and allowing him to grow in power and force to challenge them...but things are very strange in the Warp, while all the area of this infinite realm of Chaos is fully under his control, and constantly reaching out to link with him, the domains of his rivals, its completely separate from the rest of the Warp.
This should be an impossibility, it's illogical to the Machine God-in-Making, whatever force that the other Dark Gods are using to secure their domains, interested the Arkefine.
Sending mental commands to the Silent Ones, to tunnel towards the edge of the Nethervoid, Blood Lands, Sorcerer Realm, and the Plague Garden to observe for him...as the tunneling, worm like construct hellbeasts, let out a whirling sound from their maws, acting as a roar, and leaving to do as the Arkefine commands...with this at least some of the Arkefine's concerns will be sated.
(Laharl/Carnage God POV)
Location the Nethervoid-Top of a Lone Mountain of Creation, Inside the Sphere of Baetylus
I was in my futuristic and divine workshop, just in front of the worktabble, smashing my daemonic smith-hammer, onto some Necrodermis in order to create some artifacts using this living metal, along with my new divinity over "Cold", not for me or my family, or the other members of the Chaos Pantheon.
But instead for the future, greatest servents of Chaos...the Traitor Legions of Astartes.
With the Unification Wars, happening on the now named Terra, soon the future Emperor of Makind, shall win and become the new messiah of humanity, he'll start his new project.
After purging the Thunder Warriors, using his personal legion of Custodes, then start rebuilding the desolated lands that was Terra, lifting humanity to a new age under his rule.
Later talking to Amar Astarte, (Lore here is a bit effie, since originally it was a mortal that designed the Space Marines, now lore states it was the Emperor and Malcador, I'm going with the old lore, cause it was more interesting.) who was a scientist and a member of the Imperial scientific team that developed the gene-seed and other technologies that allow for the creation of Space Marines.
Then our mortal enemy, and wannabe human, will have a epiphany, that he can't lead soo many warriors alone...I smile, as I stop hammering and focus on the essence of a lesser daemon, a knightmare specifically who willing offer itself to be bound to this Chaos artifact of Carnage and Cold.
Whatever mortal, hopefully a member of one of the lost legions, find this and aid in the downfall of thar said legion, into my thrall...
Returning to work and thought process, soon the Emperor will become well the Emperor, and with his deal with us, which all personally make with the Anathema, knowing he'll break it, and using Erda, the mother of the Primarchs, secure the downfall of ultimate weapons of humanity, and causing untold Carnage and Chaos!!
Just as I was put the final details, on my first of many mortal artifacts, I receive some psychic calls from my daemons.
Seems that they'd spotted some unknown daemons, at the edge of my realm...laughing, seems that are Brother-to-be, is getting curious, honestly I expected him to do something like this long ago.
Better tell my younger brothers, about Vashtorr's actions, and prevent them from acting rashly...as I sent my psychic message to them, I continued my work.
(Khorne/Blood God POV)
Location the Blood Land-Khorne's Private Coliseum
I was in my private training ground, that I made beside the Gore Fortress, in a smaller stature, I was with my daughter, Painwheel, training her.
As she'd attacked me with her shuriken like attachment on her back, her blades spinning and scrapping against my Unmaker, despite her being a recently ascended Godling, and not at my strength, she'd bore blazing fury, courage, and strength that is worthy of a daughter of Khorne and Valkia!!
Pushing back forcing Painwheel to disengage, her stance close to the scarlet ground, her red eyes focused on me, and her tail steady, not revealing any intent.
Good, and I heard my wives, Valkia and Bellona sitting of the side, complimenting our daughter.
Which is true, aside her bloodlust and battle hunger, she doesn't showed her next move, a true warrior and killer...truly my daughter, as she struck again.
Swipping her fists, and shuriken-wheel at me, I could sense her fury, as I easily block and parried my daughter's attacks, good she was starting to bend the Warp to her will, as her fists and shuriken starting sparking hellfire.
Parrying her last attack, knocking her away, rolling back to avoid harming herself and leaping black to get back on her feet, yes she was getting stronger and more skilled, but it was enough for now...
Grabbing onto the handle of my Unmaker, and stabbing it in front of my form, showing a posture of strength and rage, I said to Painwheel in a firmed tone, "Enough!! You've done well my daughter." Painwheel, lowered her guard and stood straight, bowing to me with respect, and saying, "Yes, father."
I smile underneath my helmet, walking over to her and petting her brown and now partly blood red hair, careful to not harm her horns.
My affectionate touch, making Painwheel jump, before relaxing and embracing happily my affection, when suddenly to my surprise, she'd rush over and hugged my waist...
Shocked at first, but this is my blood-adopted daughter, I stop my shock and hugged her back...feeling my daughter, and wives affection toward me.
Only them shall see this side of me, while I'll be more firm with my still infant son, Krom, he'll never or Painwheel, will feel my scorn, hate, or anger.
Painwheel stopped hugging me, and waited for me to lead her, which I did walking over to Bellona, and Valkia tenderly holding the bundle that is our son, in her arms.
Just as Painwheel and I reached the center of this crimson field, I felt something trying to contact me, psychically, immediately realizing that it was brother Laharl, I turned to Painwheel, and told her to go to her mothers, as I needed to psychically speak to her uncle.
Nodding to me, as she'd rushed ahead of me.
I'd answer the Dark One's telepathic call, saying to him, "What do you want, Dark Harbinger?" Laharl responded to me, "Caught you in a bad time, brother?" I scoff, telling him what I was doing without shame, earning praise from my brother, stating that Painwheel and Krom in the future shall be powerful, and bloodthirsty Gods of Chaos.
Turning my gaze over to my family, as Bellona and Valkia praised Painwheel, and my son reached out to his older sister...I responded to Laharl's statement, "Of course they will, they are children of the Blood God, afterall!!" I receive laughter from my elder brother...irritating me, as I asked, "Enough of you're mockery!! Tell me why you'd call me, Laharl!!?"
Laharl apologize for laughing, and complimented my paternal pride...I appreciate his words, not that'll tell him, as he started telling me, that Vashtorr started making his moves, and seems he was interested in our domain.
Sending spies to the edge of Orchain Shield, the Dark One, told me this warning so I or my infernal legions, don't do anything rash...sometimes I regret, accepting Laharl's diplomatic approach on handling the Machine God, I expressed gratitude for the warning to my brother.
Cutting the psychic call, sending a divine command to my daemons in the borderline of my Blood Lands, not to engage the intruders, but keep watch, with that done, I banish my sword and walk over to join my family...
