Grave/Digger

You're an ordinary Imperial (any class, from soldier to vanguard).
You woke up in the barracks as usual and headed to the mess hall. Walking through the Imperial base, you saw two Jaegers setting up their traps. Lancer sharpened his spear. And Rook, under the officer's orders, was replacing old and flimsy beams to minimize the risk of collapse. Arriving at the mess hall, you grabbed your stew and sat at one of the tables, eating until Officer Eva, somewhat enraged, burst in. Many of the soldiers, who had been there before, weren't surprised that Officer Eva was so angry, and only a few looked at her and put their eyes back on their plates.

Officer Eva: So, I've heard a rumor that one of you decided to steal ammunition for one of the checkpoints. Officer Eva stood on the table in the center of the dining room , and I hope the thief decides to confess before the search, she said in a very irritated and angry tone. Then she jumped off the table, passed almost all the tables, and stopped at you. Looking over your back, straight into your soul, she said, " I'll be waiting for you in the officers' office. If you're not there after breakfast, it's too bad for you. " After which she left the dining room. Clearly, she had some plans for you.

The story of Grave/Digger follows the real-life timeline until the end of World War I in 1919, after which it shifts to the current game situation. After 1919, the world was divided into two parts: the Golden Empire and the Royal Nation. Due to differences in the empires' ideologies, as well as the assassination of Prince Leido, the heir to the royal throne, the first bombs fell on the Golden Empire, triggering a war between the queens and kings. Soon, the bombings devastated the planet's surface, making it uninhabitable. The world was covered in radioactive dust, and people were forced to retreat underground. Despite this, the war continues.

The Golden Empire consists of Great Britain, Germany, Italy, France, Russia, Japan and most of Europe except Poland.
The Golden Empire arose after the upheavals of the First World War, under unclear circumstances.

The Golden Empire is an authoritarian monarchy, led by a centralized monarch (the Queen). They are religious and value unity and brotherhood among themselves. They have a conservative approach, specifically, they wear older, medieval-style uniforms, but still use firearms to prevent opponents from gaining an advantage.
Countries included in the empire: Russia, Germany, Japan, Italy, France.

The Royal Nation is based on the United States, and its uniform is based on German and American uniforms from World War I. The name can be shortened to 'Nation.'
The Royal Nation emerged from the turmoil of the First World War, or "Sleepless War," under unclear circumstances.
The Royal Nation is a democratic country governed by a council of kings. They are characterized by democracy and embezzlement, as well as childish military discipline. Their uniforms are more modern in keeping with the times. Countries included in the Nation include the United States, Canada, Brazil, and Poland.

Solariums are the golden mean among all; they supply both sides with weapons, ammunition, and everything else necessary for war, which is why both sides do not attack it.
