WN/Sovereign Alliance of the Nasca Namrium Ulmeria Empire

The Eastern Empire is large military nation that is known as the strongest nation in the entire world.

Background
The Eastern Empire was a military nation that increased in size by absorbing its weaker neighbors. It invaded when it wanted and trampled down anyone in its wake. So it also made full use of spies.

“Death to those who disobey!” This was the principle they live by, so if the targeted state didn't swear allegiance within a week, they immediately invaded. Their sphere of influence failed to extend into the Jura Forest, though there had been victims among nearby states that had fallen to the Empire. The country itself is filled with people with various skills and knowledge. The Empire also welcomed world travelers with open arms, and most of their influence changed the empire.

There were two individuals with absolute power that have authority over the rest: The Emperor himself and the Generalissimo. There were also others who were the de facto commanders that had control over the armed forces of the Empire. They were powerful enough to surpass the demon lords' standard level, and had ensured the Empire's safety for hundreds of years. These de facto commanders were positioned as the three Generals. These three commanded each of the three Corps of the Empire's armies. The Generalissmo and the Generals, these four men were the pillars of the Empire. Each had been given the Empire’s treasured God-tiered equipments - equipments of unbelievable power/the strongest equipment before which no man can be an equal to. The Generalissimo  himself and the de facto commanders also had the duty to protect the Emperor with the Guardsmen - the Emperor's personal guards/ The Royal Knights.

The Royal Knights: A hundred individuals of great power joined the Royal Knight Corps; their strength was legendary. Of course, many of them were from another world. The Empire did not discriminate against world travelers, and recognized only strength. To these one hundred, the Emperor bestowed legendary equipment. These one hundred are the Empire’s strongest force.

Chronology
Empire’s Invasion Arc

940,000 men from the Armored Coprs were completely annihilated by the Monster Country Tempest, which were invaded by the Empire. and had their souls reaped by Rimuru Tempest, the King of Tempest.

However, The Demon Lord Rimuru revived 740,000 among them for Tempest's laboured servitude and put curses on them so that they wouldn't be able to oppose Tempest ever again. These left 200,000 souls that were completely destroyed during the war and, thus, were the only "real" casualties of the first battle between the Empire and Tempest.

Ryuma Clash Arc

90,000 men comprised of the Beast Corps and the remaining Armored Corps, which included 30,000 Magic Beasts, 30,000 Magic Beast Riders and 30,000 Mages, were completely annihilated by Demon Lord Rimuru and the Black Corps/Numbers of Tempest upon invoking the Demon Lord's wrath by taking control of Storm Dragon Veldora, who's Rimuru's friend.

10 Strongest Royal Knights also fell victims to the Black Corps in the battle.

Only Vega (Yuuki's spy for observing the Beast Corps), the Emperor Rudra and Scorch Dragon Velgrynd survived the battle.

Among the 300 Airships in this battle, 200 were salvaged for Tempest under Rimuru's order.

Principles
The Empire is found upon the maxim that strength is everything.

Through inter-army duel and combat, a system where the young may usurp the seat of the elder was established. Though forbidden during Army's marches, any members of the army could challenge a superior to a duel if they believed they can surpass their superior. If they were defeated, they would have to wait a year before they were permitted to challenge the superior again. As such, everyone continuously sharpened their skills.The best system for a country where strength is everything. In addition to the position of a captain or a general, there's also the position of the Emperor's personal Guardsmen/Royal Knights that held great influence and power within the Empire. These positions were always filled with powerful individuals who can not be easily defeated within the Empire. As a result, if you wanted to rise in status, you would wait for an opportunity to defeat them.

The Empire increased its influence by absorbing weaker nations and invading nation that did not submit. With this principle, If the targeted country did not swear allegiance within a certain time, they would be immediately invaded by the Empire.

The Eastern Empire was known as being the strongest military state in the world.

Empire’s military is split into three divisions/corps:

The Armored Corps: A Marvel of Technology by Imperial Engineers.
They rode modern tanks and symbolized the Empire’s technological prowess. The Armored corps, where science and technology of the different world were fused as magic technology, is the largest Corps with the largest number of soldiers that could be mobilized exceeded 2 million. In reality, however, the number of soldiers who could participate immediately in military deployments was 1 million  The remaining were on standby in various places within the Empire. Even so, the scale of the corps could be considered abnormal.

The Armored Corps that could participate in the military deployment consist of:

1. Armored Remodeled Legion-Legion of soldiers who received magic remodeling by magic and technology of the different world. The individual ability increases and has ability considerable to B - A ranks. Even at the lowest of the corps, the soldiers could still be considered to be stronger than C+ rank. Number of soldiers affiliated: 700,000 people.

2. Magic Tank Division-Magic Tank 4.000 units. Number of soldiers affiliated, 200.000 people. The Empire’s secret weapon, each tanks were piloted by 5 people. The main armament of each tanks was Magic cannon optimized by other world’s technology, the cannon was used by amplifying magic and firing it.

3. Aerial Fighter Legion-Airship 400 aircrafts. Number of soldiers affiliated, 100.000 people. One aircraft can be boarded up to 400 people. Operating one aircraft needs about 50 staff. The other personnel is to be engaged in bombardment. It’s also useful as transportation for large scale military deployment. Since it could be said that there’s no concept of air supremacy in this world yet, the Airships can be considered to be invicible. Magic Reinforcement Cannons are installed on the airships. The airships which could be called an air fortress also had the largest magic canceller devices installed in them. In control of each devices was the elite-wizard-class member who commanded the magicians. In battle, the airship  fires the magic cannon that has the equivalent power of the main armaments of the 4,000 magic tanks, thus, it can kill with one shot of the magic cannon a  Young Dragon  of A Rank.

Magic Canceller (Magic Essence Disturbance Radiation). It can obstruct a magician’s casting. A technology that enables the weakening of a monster in battle.

The Magic Beast Corps
From the four corners of the world, the Empire brought beasts of wonderful strength and forced them to obey. They symbolize the Empire’s strength. magic beast corps captured various magic beasts, breed, strengthened, and trained them The culture of the magic beast was by DNA analysis, the technology of the otherworld the strong soldiers of the empire riding beast

The strong people with were said to have the blood of the hero who played an active part in the old times magic remodeling was a technique to change an ability-less person into a hero,they are Born Heroes having an overwhelming ability. A minor Corps with only 30,000 personnel was said that one of them had the ability of 10,000 people the magic beast they rode, all had the strength appropriate to A- Rank.

The Mixed Corps: A Group of Engineer Rejects and Beast Exiles.
These members are too powerful and too smart to work as a single organization.generally thought However,while it may be true that they were dropouts,it didn’t mean they don’t have ability and as well various experiments and trials are carried out by this corps The corps own their own technology development department, it also have magic research department it potential is unknown.

This corps employs the most Otherworlders as combatants. The total number of soldiers, 200,000 people. However, a lot of them were intelligence officers and general office work soldiers, the number of soldiers that can actually fight were around 100,000 people. In disfavor of Magic Remodeling, people who can’t ride magic beasts and people of the former magic corps that have no place to go were taken into this corps.

THE Royal Knight Corps: 100 Empire's Greatest Elite Fighting Force.
They're the one who guard, receive the order and under direct control by the Emperor himself, only consist of 100 A+ rank Member. No.1 is Sage which bestowed with Myth Grade Equipment by the Emperor himself. No.2-10 Royal Knight is the Sage who had Receive Ultimate Alternative by the Emperor himself. Each and every single member except NO.1 Royal Knight receive Legend Grade Equipment from the Emperor himself.

Method of Attack for Tanks and Airship (Armored Corps)

 * Along with the shell type that packed magic essence and increased the destructive power, the tanks contained another attack that fired a converged magic essence gathered from the air like a beam.If it’s a shell, it’s possible to accomplish rapid fire even if the quantity is limited.In case it’s a beam, energy charge takes time of a little over three minutes but there’s no quantity limitation for it. Because it’s possible to alternate between these two types of attacks, the beam type is shot first and the normal shell is shot during the time it takes for the next beam to be charged.


 * Adjustment of the magic amplification cannon was vital. Also, the magic barrier was laid out to always protect the airship.Furthermore, Shield (Wall Shield), which is a magic to deal with physical attacks, is amplified to prevent attacks to the airship.The spell of the magician who usually fire it was amplified to 20 times of its power by  the magic amplification cannon.It's a cannon only in name, actually it’s just a pedestal with an ability to amplify the used magic.A huge spell control orb was made with a magic stone of high purity. Originally, orbs which were attached to staffs were as big as a fist due to spell amplification effects, various large-scale magics were able to be casted.
