Primarch and Honkai Impact

Since then, Mars has become part of the Empire, the double-headed eagle flag has been unfurled,

The great expedition is about to begin.

Like the legendary gods of Ancient Terra, the Primarchs swept across the battlefields of the galaxy, their power proving irresistible.

However, the Primarchs, for all their displays of superiority and seeming immortality, were still human, and they possessed too many of the same human flaws that had plagued humanity since its inception.

The most beloved of the Emperor's creations, the Warmaster Horus, was seduced by the Chaos Gods.

and convinced half of his brothers to betray the Emperor. The battle between the two giants shook the Imperium to its foundations, forcing former friends and relatives to confront each other in a rebellion known as the Horus Heresy.

Lorgar the Word Bearer was the culprit of the rebellion of the Nine Legions. Lorgar did not forget to spread the belief in worshiping the Emperor as a god during the siege of the city. This made the progress of the Seventeenth Legion slow. The Emperor ordered the Ultramarines to bomb the Perfect City. ! And let Lorgar and the 17th Legion kneel down in the ruins to repent!

The Ultramarines and the Word Bearers have become enemies since then. The Chaos sect's prophetess Kalfiro induced Lorgar (the Emperor didn't let Lorgar believe in him as a god, but Lorgar insisted on believing in him. If you don't let me believe in you, then I will Worshiping the Others), Lorgar and the Word Bearers eventually converted to the Four Gods of Chaos.

seventh year of rebellion

In the final battle of the Civil War, Horus took the initiative to invite the Primarch of the Blood Angels, Sanguinius, and the Emperor for a decisive battle as loyalist reinforcements were about to arrive. At the culmination of the final confrontation during the Siege of Terra, the Emperor and the Warmaster clashed aboard Horus' own flagship, the Glory-class battleship the Vengeful Spirit.

The Emperor was unwilling to use his full psionic powers on his most beloved son, and it was not until Horus crippled the Emperor and killed Sanguinius that the Emperor finally unleashed the full extent of his unimaginable psionic powers.

Horus engaged the Emperor in a duel during his attack on the Earth Palace, in which he was defeated and killed, but the Emperor was also seriously wounded.

He eventually defeated the Warmaster and even eradicated the Warmaster's soul from the Warp, with such destructive power that the Four Gods were unable to restore their puppets.

Most of the remaining Traitor Legions fled into the Eye of Terror after Horus' defeat, and their Primarch sold their souls to Chaos to become Daemon Princes who ruled a small realm within the corrupted realm of the Eye of Terror. Empire of Chaos.

The Horus Heresy caused immeasurable damage to the Imperium. The Emperor was moved into the stasis field of the Golden Throne so that he could maintain a semblance of life. He only had enough spirit to maintain the Star Torch and could no longer rule the entire empire personally. Although the rebels retreated into the Warp rift known as the Eye of Terror, it took hundreds of years for the Imperium to quell the aftermath of the rebellion. The legions that remained loyal were divided into many small "war groups" to prevent the mistakes of the past from being repeated.

The Imperial Navy was born from the re-splitting of the Imperial military forces after the Horus Heresy. The original Imperial Army was split into the Imperial Navy and the Imperial Guard, the latter of which would later become the Astra Militarum, known as the Emperor's currency. This move is similar to the original intention of splitting up the Legiones Astartes, which is to avoid placing a huge military force under the control of a few people.

While most histories have only emphasized the impact and divisions on the Imperial Space Marines caused by the military reforms following the Heresy, since those who sided with the Warmaster during the Horus Heresy were present in almost any major organization or faction, the impact of the Heresy's After it ended, nearly every corresponding organization was punished with more severe restrictions or breakups.

The Adeptus Mechanicus was reorganized into the Adeptus Mechanicus. The shock caused by this move even exceeded the Great Heresy itself among the followers of the Mechanicum. As compensation, the Adeptus Mechanicus was given the highest theoretical governing body of the Empire after the Emperor's ascension. , a fixed seat in the High Lords Council.

The Cybertronic Legion, which "performed outstandingly" in the Great Rebellion, was an organization within the Cult of Mechanicus that specializes in combat robots and automated warfare. Particularly strict restrictions were imposed on them, prohibiting them from crossing the boundaries of the Crimson Agreement.

The Titan Legion and the Knight House are subject to fewer public restrictions. This is because they have lost the Space Marine Legion system and it is difficult for them to maneuver in the subspace and launch battlefields (these tasks were completed by Space Marine troop transports during the Great Crusade). , the Assassin's Court and the Mechanicus also sent spies to these families.

The split the Imperial Army suffered was the most sophisticated and prudent. The void combat forces in the Imperial Army included fleets, fighter groups, troop carriers and gunboats with subspace maneuverability (according to the old setting, some of HNA’s heavy fighter aircraft were equipped with navigators and warp engines) were reorganized into the Imperial Navy.

A fleet after formation will generally have no more than forty ships, of which there will generally be no more than twenty battleships.

The remaining mortal legions, which did not have long-distance physical space mobility or subspace mobility, were further divided. Similar to various modern military services, the super-heavy armored regiments were mainly equipped with super-heavy tanks such as the Emperor's Baneblade or Shadow Blade.

But it will not have a large number of infantry and long-range artillery. Similarly, the infantry regiments and artillery regiments only have limited armor strength. At the same time, most of the fighters used by the Astra Militarum only have the ability to maneuver within the atmosphere, and only a few can enter the universe (.

The result of the split is that the rebellion of any single battleship or Imperial Guard regiment is not enough to pose an unmanageable threat to the Empire. At the same time, due to its limited self-sustainability, the Empire with supply and intelligence advantages can quickly defeat it.

On the one hand, it is true that the Horus Heresy greatly weakened the empire's national power and caused the empire's originally ideal leader, the human emperor, to no longer be able to directly lead the empire. However, in fact, the rebellion caused a blow to the war will and material losses.

Mainly material losses, technological losses are immeasurable and irreparable.

The Empire no longer has the ability to build giant battleships, such as the Emperor-class battleships or the Glory Queen-class battleships, or even the "Super Glory Queen" class. This is largely due to the loss of related technologies and the dispersion of resources, especially after the completion of the Abyss Fury class. The former Martian Foundry Director Cobo Hal secretly ordered the destruction of the Jupiter Pole Orbital Dock where these giant ships were built, which caused the Adeptus Mechanicus to almost permanently lose the ability to build such ultra-large warships.

These warships are so massive that not only are they unable to maintain their form without built-in gravity stabilizers, their construction must also take place in the Warp.

Thousands of years later, humanity continues down a dark path. The loyal Primarchs are long dead or missing, and the future of humanity lies in the hands of the bureaucrats and Ecclesiarchy who run the Imperium in the name of the Emperor. The Emperor's Golden Throne requires the sacrifice of the souls of a thousand psykers every day to maintain the brilliance of the Star Matrix (relying on the Star Matrix, human ships can navigate the warp), turning the technology that once led mankind to glory into Superstitious idol. The power of chaos is everywhere, alien races are accompanied by endless threats, and the soulless Zerg are trying to devour the entire galaxy.
