Gran Chaos Empire

Gran Chaos Empire is a nation situated in western Landia and is the largest in the continent in terms of territory excluding Demon Lord's Domain. The Empire is considered the most powerful nation in the world and has numerous vassal states. However it also has the largest border with the Demon Lord's Domain and is attempting to unite the nations of Landia under the Mankind Declaration to counter the invaders. The current Empress of the Gran Chaos Empire is Maria Euphoria.

It currently shares borders with "Star Dragon Mountain Range", "Mercenary State Zem", "Republic of Turgis", "Orthodox Papal State of Lunaria" and the "Demon's Lord Domain".

History
The predecessor to the Gran Chaos Empire was the Chaos Kingdom which was founded during the troubled time known as the Chaotic Period. The Chaos Kingdom was founded under a powerful human king and power was centralized around the king to the level of a dictatorship. This system allowed the Kingdom to become one of the powerful nations after the end of the Chaotic Period.

Around a hundred years before the current events Manas Chaos was born to the royal family and inherited the throne after the death of his father and elder brother in war against the Euphoria Kingdom. As the Euphoria and Chaos Kingdoms were almost equal in power Manas decided to avoid war for the moment and married the daughter of the king of Euphoria Kingdom and took the name Manas Euphoria. After dealing with dissenters and absorbing nearby smaller nations, Manas invaded the Euphoria Kingdom and conquered it. After the conquest Manas continued to expand the kingdom and renamed it the Gran Chaos Empire but did not take back his old name. Thus the royal family of the Gran Chaos Empire would carry the name Euphoria to the modern day.

Manas who became known as Emperor Chaos died at the age of fifty. The second emperor maintained stability with the aid of loyal servants of Manas. However as a result of the Empire being a predominantly human nation the royal family lacked vassals from long lived races. Thus by the time of the third emperor the loyal attendants of Manas had passed away. In order to gain support and consolidate power the third emperor launched a series of invasions in an attempt to emulate emperor Manas which would backfire creating a world wide war that caused the nations including the Empire to become weak. With support for the emperor eroding the Empire faced a series of civil wars with the third emperor dying at the hands of rebels in one of such conflicts.

The fourth emperor abandoned the expansionist policies and focused on domestic issues but was considered passive by the lords and by the time of the fifth emperor the Gran Chaos Empire appeared to be on the verge of collapse. However the sudden appearance of the Demon Lord's Domain resulted in the Empire being invaded and its northern territories including that of the former Euphoria Kingdom falling into the hands of the enemy. As the most powerful nation in Landia the Empire led an alliance of nations against the demon forces and successfully pushed deep into enemy territory only to suffer a crushing defeat. Not being a skilled warrior or a general like the past emperors the fifth emperor passed away without leaving any male heirs.

The death of the fifth led to the fourteen year-old Maria Euphoria inheriting the throne becoming the first empress of the Gran Chaos Empire. Using her charisma empress Maria carried out large scale reforms which resulted in the integration of non-Humans and the creation of the Declaration of Mankind's Common Front Against the Demon Race more commonly known as the Mankind Declaration to unite the nations of Landia against the demons.

Politics
The Gran Chaos Empire is a monarchy ruled by an Emperor. The current Empress Maria Euphoria is known for being an idealist, and has carried out large scale reforms, and the Empire is seen as the main stabilizing force in Landia. The Mankind Declaration Treaty is used as the guideline to keep the other nations in check, and to form a united front against the Demon King.

However, the Gran Chaos Empire is not without its flaws and the idealistic views of its empress do not reflect the actual conditions of its citizens. As such, it has begun to take notice and even adopt some of the reforms and innovations of Friedonia. Furthermore, instead of forcing Friedonia to become a signatory of the Mankind Declaration Treaty, the Gran Chaos Empire and Friedonia have secretly set up a bipartite alliance between each other.

Military
The military of the Empire is considered to be among the strongest in Landia with five times the numbers of the Elfrieden military and ten times the military power due to superior technology and equipment. Imperial army uses specially trained Rhinosauruses to carry large cannons, using them as mobile artillery platforms. The Airforce has griffon knights in addition to wyvern cavalry. Griffons are superior in speed and agility being equal to fighters compared to wyverns whose superior range and endurance make them equal to bombers. As the only nation with griffon knights the empire has large advantage in aerial dogfights. In addition Imperial mages vastly outclassed Elfrieden mages. The Empire also has a capable intelligence corps which is used to gather intelligence and carry out covert operations.

One of the most powerful units in the imperial military is the "Magical Armor Corps" which is a unit consisting of elite pikemen equipped the black full-plate armor that emits a barrier that blocks all types of magical attacks. It is said that every step they take expands the empire due to the massive advantage they provide to the imperial forces.
