Hundreds of millions years ago. Everything was so chaotic. Death here, death there, death everywhere. The 9 primarchs led 9 armies to fulfill their actual job of being humanity's greatest. Their revival isn't known to a wider Imperium. The wider Imperium knew that they're Primarchs, but they only knew those are not the original Primarchs from before.
Of course that's what they knew and what the government want them to know. For about a couple of years since the Primarchs got revived at least.
The Ecclesiarchy, deliberately spread interesting rumours that the Emperor has ascended and can now revive the dead if he wanted to do so without breaking a sweat.
Though some of the elderly at that time knew that the Emperor has the power to revive anyone and basically turn them into a literal angel with a matching pair of wings, golden armor, and a melee weapon with some fancy name, typically has something to do with killing infidels, or bringing his wrath.
The Imperium easily plunged into a religious festivity fueled by fanaticism. They never treated whatever the Ecclesiarchy said as rumours after all, the Ecclesiarchy is responsible for people who will enter the kingdom of god after death. No, most if not all treated them as facts. The Ecclesiarchy kind of like became a second news distributing agency aside from the state controlled media.
They sang praises to him, built statues, and constructed churches that were named to honor his most notable warriors. Every single thing related to praise and worship was done for him during this time period.
Everything boomed. The production, the war effort, the offensive suddenly gained an even stronger fire that lead to the collapse of the enemy in less than a year or two.
The Imperium's central government on the other hand. Just looked away, and never really confirmed anything. Denying nor acknowledging everything. They kind of let a placebo effect of some kind take place.
After another millions of years, this belief still stands firm. This, and a couple more rather absurd things that the Central Government and the Emperor himself never really took seriously at all.
On matters of the state. The Imperium has experienced what everyone liked to call Pax Imperator, or Emperor's Peace. No war, no large scale conflicts that demanded the war machine to be turned on at all. The conflicts that the once proud Imperial navy fought are but a thing of the past. The battles they usually fought in are monster hunting related games or mission.
But of course, this era of peace never meant that the officers and soldiers are complacent and are weak compared to the veterans from before.
They're better trained, equipped, and the only thing they lacked is anti personnel experience. Even with all advance VR, and AR technology present, couple that with the they didn't really need to fear death as they could just be revived using a copy of their consciousness uploaded on the cloud. But they lost ehat you'll a desire for war, they instead acted more like a self defense force of some sort as there's really no one for them to use their weapons.
Anyway, back to reality and present. The Imperium is gearing for war. After more than 700 million years of peace, the lock has been finally destroyed. The Pandora's box has been opened, partially at least.
For the very first time, the space marines wore their proud armors for designed for battle. The varying colors looked like a rainbow to many.
The proud insignia of their chapters shone brightly due to the light. Their helmet that made them look cold, calculating, and screamed deadliness.
The red light on their eyes made everyone who glances or directly looks at it shiver to the extreme. Their metallic boots that stomped the floor made a sound unique to their power armors.
Each of these space marine picked their most favorite weapon from their chapter's arsenal. Some went for heavy bolters that has some insane, completely unrealistic, and doesn't follow any science at all. These heavy bolters are the cream of the crop.
They basically have a pocket dimension as its bullet magazine. Each pocket dimension can hold up to trillions of bullets. But even with the sheer amount of bullets it contains, it wasn't enough on the eyes of the people who created it. Therefore, they made the fire rate of the heavy bolter extremely fast. It's faster than the currently fastest spinning object known to man by a large margin. The gun can fire at least a million bullets per second if needed.
Once those things go full auto, even a planet will have a hole drilled. Then to the flamers, the flamers are somewhat unique. Their flamers has different levels of firepower. The lowest can easily turn a good portion of New York to ash in a second. The highest basically has the power to turn a whole continent the size of Eurasia to ash, so it's mostly used on space for pest control. These two are just some of the more mainstream weapons used by a space marine so you bet they're over the top and completely overpowered.
On the side of the Imperial navy, a group of battlefleet with ships that number to around a thousand in total was transferred to the border adjacent to the target universe.
A special way of transportation will be used to instantaneously teleport these ships right above the enemy.
Moreover, this battlefleet group will not be some half-baked invasion group. Rather, it will be an actual invading force that has all the necessary tools and equipment to crush anything and anyone that stands on their way.
On a large space dock the size of a couple of of galaxies...
Rows upon rows of tanks, armored personnel carriers, motorbikes, artillery guns, and many more land based vehicles can be seen slowly loading themselves on the gigantic battleships currently docked on the space station.
Then on the back are the soldiers. Each wore special power armors while carrying a standard issue gun on their hands.
They marched gracefully, and full of discipline. Each raise and stomp of the foot are so coordinated that one would think the whole scene before them is a product of computer graphics simulation.
Each stomp is mesmerizing to look at. Everything stretches for as long as the eye can see. But even then, it still seemed to never end.
The steady, and coordinated movements slowly entered on their assigned battleships in an orderly fashion.
On top of a command center, someone sporting a clean black trench coat filled with military awards. Medals with different designs, colors, logos, and insignia from one another are strapped right on his right chest. He looks mature, he has a fairly muscular body, a trimmed beard, and a short hair.
He is sitting on his chair while resting his cheek on his hand, looking at a table in front if him with a lit up 4d map of the whole universe.
The map showed everything related to the universe. Elements, the civilizations including the primitive, interstellar, and the would-be civilization. The military capabilities, technology level compared to the Imperium using historical data, and many more.
It's really comprehensive and detailed for a map.
The Lord Admiral is currently studying it while letting the strategists assigned to this battlefleet group to do their job.
He can understand the importance of the Alpha Centauri for the other side. It holds some of the secrets of the universe that they still haven't unearthed due to their own technological limitations.
The map however, highlighted something they locally call as Mass Effect Relays. It says that it's a piece of teleportation sort of transportation almost similar to what the Auxiliary army used to enter the adjacent universe but highly dissimilar as what they've used are but crude pieces of technology.
Just then, the strategists finally formalized the battle plan proposed. The plan said that they'll divide the whole group into 10 corps, with a battlefleet whose ships number to 100 are assigned to each corps.
The plan also explicitly stated to use Napoleon's style of warfare. Divide and conquer. Isolate the smaller force, then start to eliminate them while preventing reinforcements.
At this moment, the Lord Admiral stood up and did some stretching. He cracked his fingers and walked to the table to join the discussion.
"Sire, we have a problem." a strategist said. His voice is full of concern.
"What seems to be the problem?" the Lord Admiral replied with a simple voice while looking at him.
"We need to reconfigure the weaponry strength, sire, or else..."
"We risk destroying a good portion of the galaxy if we left it like what it is now..."
Still can't find any inspiration sadly.
