Actaea

Long, long ago, about thirty years ago, there existed a small but very developed and wealthy state called Epylandia. It had a southern region and a mountainous terrain, and one of the largest rivers in the world began to flow from it. Other states constantly made Epylandia richer and richer, lending it money at interest, not to mention trade, which grew year after year. The Epylandians were hardworking and educated, knew many languages, and could solve TFKP problems in their heads.
Probably, things would have continued this way, but then came the era of satellites. One day, one of them flew over Epylandia and took detailed photographs of the country. And then the Epylandians were shocked: the satellite discovered an entire city right next to them. A huge city with strange structures like pyramids, and all of this was hidden in such a... in such a place that no one had ever seen this city.
Immediately, a large group of researchers and archaeologists were sent there. Upon arriving at the site, to their surprise, they discovered a whole bunch of savages. Absolutely naked savages. And these savages suddenly grabbed sticks and, with clearly unfriendly intentions, rushed to attack the strangers. The Epylandians ran so fast that even marathon runners would envy them, and, reaching their cars, they developed a speed close to Formula 1 records.
"Well, that's it!" sighed the unfortunate archaeologists and researchers, reaching the city. The adventure was scary and dangerous; they were almost killed, but at least they would have something to tell their children and grandchildren! And yes, they definitely need to tell the public about the discovery. Wait a minute, what is that in the distance, behind the mountains? It looks like a landslide, right? But why are the stones falling everywhere at the same time? Or are they not stones?
The next few minutes were a nightmare. Hundreds of thousands of naked savages with sticks stormed into the city. They instantly crushed the police and the army, occupied all government buildings, and, moreover, all the supermarkets: there, the savages immediately began to experience the pleasures of civilized life in the form of chips, chocolate, and popcorn.
In a matter of days, Epylandia ceased to exist, and absolute anarchy reigned in the country. With superhuman efforts, the Epylandians managed to establish contact with the savages and establish at least a semblance of a parliament in the country, but the vast majority of parliamentarians were savages, not Epylandians. Simply because otherwise, the savages threatened to eat all the Epylandian notebooks, believing that it was something like parsley or salad.
The Epylandians reconciled themselves to their new government. After all, they decided that such smart and educated people as they were, sooner or later, would positively influence the savages and their IQ. Only, decades passed, and now we can see that exactly the opposite happened. People liked the absolute freedom and permissiveness so much that the vast majority embraced the ways of the savages and completely merged with them.
The savages themselves, due to their special traditional fondness for mushrooms, were called Champignons, and a little later, this name became the new name of the country and its inhabitants.
The currency in the country is marmalade. This is a special, extremely rare hallucinogenic mushroom of red color, growing in very, very difficult-to-reproduce conditions. So, in fact, the cultivation of this mushroom by the SRSh government and some particularly large corporations is the printing of money. It is impossible to counterfeit them if you are not a billionaire, and if a billionaire is involved in counterfeiting money... Well, so what, let him pay a kickback and be on his way.
