Fantasy world. (Jujutsu Kaisen)

This is the modern world, almost the same as ours: cities, states, the Internet, cars, universities, corporations, medicine and high technology.
But humanity exists next to another world, the world of ancient beings and supernatural peoples.
These two worlds do not mix.
Humans do not live among witches, spirits, demons, or fairies. Most people never encounter them in person at all.
There is a clear border between the territories, established many centuries ago.

The Great Treaty is considered the main document of peace.
It appeared after an ancient war, when numerous races almost destroyed each other, trying to establish their own order.
After the war, representatives of the most powerful nations made an agreement:
No nation has the right to subjugate or destroy another people.
From that moment on, territories began to be divided, and interference in the life of other peoples was regulated by laws.
It is the Great Treaty that is the basis of the modern world order.
Its violation is not considered an ordinary crime, but a violation of the world balance.

the highest political authority of the supernatural world.
But it does not represent every race that exists.
Otherwise, several hundred representatives would really have to be imprisoned there.
The Council includes only the Superior Peoples - the oldest and most influential races capable of independently representing their interests and maintaining their own territories.
Each superior nation has a limited number of representatives.
The Council is engaged in:
violation of the Great Pact;
territorial conflicts;
mass attacks;
interracial crimes;
the use of forbidden magic;
the interference of supernatural beings in human civilization;
threats to the existence of certain peoples;
conflicts that can no longer be resolved within one race.
At the same time, the Council does not deal with every domestic quarrel.
If a mermaid sent a man to hell for climbing into her lake, the Council is not going to.
If a witch and a druid hate each other, so do they.
But if one side begins to systematically kill representatives of the other, this is already a matter for the Council.

🔱 The highest level
Peoples with great strength, antiquity, territorial influence and political authority.
Preliminary:
witches;
demons;
the nine-tailed kitsune;
ancient dragons;
Völuspá;
jötunn;
higher alves.
The list will still be expanded and checked by mythologies.

⚔️ Mid-level
Beings who possess serious power, but do not have such political weight.
For example:
mermaids;
MAVKA;
Druids;
ordinary elves;
Banshee;
werewolves;
shamans;
other strong perfumes.
Some individual representatives of the middle level are quite capable of defeating a representative of the superior race.
This is normal.

🌿 The lowest level
of Being with limited abilities and little political influence:
yuki-onna;
tengu;
tsukumogami;
brownies;
kikimoras;
small spirits;
inferior fairies;
water;
various local spirits.
"Inferior" here does not mean useless.
A certain lower spirit may have a very specific ability against which even a demon will be helpless.

Humans do not belong to any of these species, as they have absolutely no abilities and longevity.

This is one of the most important laws.
A person has the right to be on human territory.
A supernatural being has the right to be on its territory.
But crossing someone else's border is regulated separately.
If a person accidentally crossed the border and immediately left the territory, this is not considered a serious crime.
If he received a warning and continued to move,
the responsibility for the consequences falls entirely on him.
In other words, if a person entered the forest of witches, ignored the warning, and the witch cursed him, the Council is not obliged to save him.

The Primordials are the oldest creatures from which some races descended. Most have disappeared, died, or are sealed.
High Witches are the strongest witches who wield ancient magic and political influence.
Archdemons are powerful demons that can control other demons and use forbidden magic.
The Nine-Tailed Kitsune are the highest level of kitsune, masters of illusions, transformations, and spiritual magic.
Ancient dragons are extremely rare creatures of great power, living separately from other peoples.
The Jotunn are an ancient northern people of giants who possess great physical strength and resistance to magic.
The Higher Alves are an ancient race associated with nature, light, and the magic of life.
Völusps are northern soothsayers, able to see possible paths of the future and turn to ancient runes.

The Yautja are an ancient, highly advanced warrior people known for their technology, physical strength, and hunting. They live in tribes, although there are loners and mercenaries among them. Their culture is built around hunting, honor, and proving their own strength. A worthy trophy is considered a status symbol, and a victory over a strong opponent is the highest honor. Using technology against notoriously weak loot is considered dishonorable.

🧜 1. Mermaids
Water people.
They live in seas, lakes and some large rivers.
Abilities:
water management;
voice charms;
underwater breathing;
Faster recovery
impact on emotions.
Not all mermaids lure people with songs. This is a common myth, but especially strong songbird mermaids are indeed able to bend the will of weak creatures.
🌿 2. Mavki
Forest Spirits.
They are related to plants and nature.
Abilities:
Vegetation management;
creating illusions of the forest;
camouflage;
effects on animals;
restoration of nature.
Mavky is very territorial.
If a person wanders into their forest by accident, he can simply be taken back.
If a person deliberately destroys the forest, the attitude will be completely different.
🌳 3. Druids
Not exactly a separate race, but an ancient magical people/culture connected to nature.
That is why you can leave an interesting conflict with witches here.
The Druids believe that their power did not come from their progenitor.
According to their beliefs,
the forest itself became the first druid when it gained consciousness.
Abilities:
natural magic;
treatment;
plant management;
animals;
weather;
the creation of sacred places.
🧝 4. Elves
A younger branch of the Alves.
Long-lived, agile and magically gifted.
But much weaker than the higher alves.
Abilities:
natural magic;
shooting;
illusions;
treatment;
elemental magic.
Elves can live for several hundred years.
👻 5. Banshee
Spirits associated with death.
Their famous ability is crying as a warning.
Banshees are able to sense the approach of death and sometimes see those whose lives are about to end.
Their cry is able to:
deafen;
cause strong fear;
disturb concentration;
to cause physical pain.
But they are not immortal in the absolute sense.
🧙 6. Shamans
Here I propose to make them people who have the opportunity to interact with the spiritual world.
That is, a shaman is not a race.
This is a person who has undergone a special initiation.

Tengu
Mountain Spirits of Japan.
Very fast, agile and physically strong.
They are able to control air flows and create small air vortices.
But in large-scale magic, they are inferior to higher peoples.
❄️ Yuki-onna
Spirits of winter.
They are able to:
create cold;
freeze water;
reduce the temperature;
create snow illusions.
Strong yuki-onna can freeze a person almost instantly.
🏺 Tsukumogami
Spirits of old objects.
An object that has existed long enough and has accumulated spiritual energy can acquire consciousness.
These can be:
swords;
mirrors;
dolls;
musical instruments;
books;
jewelry.
That is why some ancient artifacts can literally have a character.
🏠 House Spirits of
dwellings.
Usually they are not dangerous.
They watch the house, can hide things, make noise at night and warn the owners of danger.
But if the brownie is angered, the house can turn into a real nightmare.
🖤 Kikimoras
Small spirits of houses and abandoned places.
Capable of causing:
nightmares;
insomnia;
a sense of presence;
minor breakdowns;
fear.
Physically, they are almost defenseless.

Humans are weaker than most supernatural peoples physically and magically.
But they compensate for this:
with knowledge and technology.
Over the past few decades, human scientists have begun to study the supernatural world.
They have developed:
detectors of magical anomalies;
invisible creature detection devices;
protective fields;
special ammunition;
materials that prevent the passage of magic;
serums against certain types of curses;
devices that determine the belonging of a creature to a certain species;
technologies for suppressing magical activity.
But people are still not able to defeat everyone.
That is why there is a delicate balance between the parties.

🌫️ 1. Silent Valley - Banshee
A vast mountain valley where there is almost never wind.
Banshees and other spirits of death live here. Sounds in the valley are strangely distorted: whispers can be heard for kilometers, and the screaming sometimes disappears completely.
The main feature: in the center of the valley is the Stone of the Last Voice, an ancient monolith near which the banshees perform their rituals.
People avoid the valley because it is believed that if you hear your own voice calling from the fog, it is a bad sign.

🌌 2. Night Plateau - Völulvy
A high plateau in the far north.
The sky here is almost always covered with stars, and at night there are unusually bright northern lights.
The Völusps use the plateau for prophecies.
On the stone surface there are huge runic circles.
Peculiarity: some runes begin to glow when an event occurs nearby that can change the future.

🌊 3. Depths of Nerea – mermaids
Not a specific lake or sea, but an underwater kingdom located in the depths of the ocean.
There are huge coral cities, underwater palaces and tunnels.
Part of the territory is so deep that even modern human devices are not able to get there.
Mermaids consider the surface to be someone else's territory.

🪨 4. Black Gorges - Jotuns
A giant mountain system.
High black cliffs, glaciers and deep gorges.
Some passages are so huge that they look like valleys, although they are actually traces of ancient battles.
Peculiarity: inside the mountains there are ancient dwellings of the Jotuns, carved directly in stone.

5. Garden of the First Tree - Higher Alves
   Not an ordinary forest.
   It is a huge enclosed garden surrounded by an impenetrable wall of living trees.
   In the center grows the First Tree, sacred to the Alves.
   It is believed that it was from its seeds that the first higher alves appeared.
   Only the alves themselves and those they have given permission are allowed to enter.

🔥 6. Red Wasteland - Demons
A vast area that resembles a scorched desert.
The ground is covered with black stone and red cracks.
There are cities of demons here, but they are completely unlike human ones.
Houses can be carved into rocks, built from the bones of ancient creatures, or literally exist through magic.
In the center is the Nameless Altar, dedicated to the First Demon.

🦊 7. Valley of Nine Moons - Kitsune
A huge valley where you can always see nine lunar reflections at night.
In fact, there is only one moon.
The other eight are illusions.
Kitsune use this area as a place for teaching and performing ancient rituals.
The main problem: a person who loses his way here can walk in the same place for several days without realizing it.

🏯 8. The City of a Thousand Gates is neutral territory
I would make this one of the most important locations in the world.
A huge ancient city located between the territories of different peoples.
He does not belong to any race.
Any conflicts are prohibited here.
In the city there are:
diplomatic buildings;
markets;
hotels;
magical archives;
embassies of peoples;
alchemical laboratories;
places of negotiations;
neutral hospitals.
It is here that representatives of different races can officially interact.
It is practically the capital of international diplomacy.

🏜️ 9. The Dead Sea is the territory of the spirits
This is not a real sea.
A huge colorless plain covered with a thin layer of water.
It is impossible to see your reflection in the water.
Spirits use this territory to communicate with the dead.
People are not allowed to enter.
Even most witches try not to approach.

🌲 10. Fields of Oblivion - Tsukumogami
A vast area of old things.
Abandoned houses, libraries, warehouses, car cemeteries, old theaters, weapons workshops.
Everything that people once threw away, but that has lived long enough, can gain consciousness.
Therefore, there are literally thousands of intelligent objects here.
An old piano can hate people.
An antique doll can talk.
Sword can consider himself a great warrior.
And for some reason, the old refrigerator is the wisest creature of the territory. 😐
🌾 11. Green Plains - Druids
A vast territory without cities.
Only fields, hills, ancient stones and small sacred groves.
The Druids believe that the land itself determines who is allowed to be here.
On the plains are the Circles of Ancient Stones, the meeting places of the Druids.
🏔️ 12. Celestial peaks are tengu
Mountain peaks that are almost impossible to reach.
On the peaks there are tengu settlements.
They build houses directly on sheer cliffs and use aerial magic to move.
People who have tried to climb there usually return with broken legs and a very bad mood.
❄️ 13. The White Land is yuki-onna,
the Endless Snowy Territory.
The snow never melts here.
The temperature practically does not change even in summer.
The Yuki-onna build ice palaces that change shape with the weather.
Peculiarity: the further a person goes into the White Land, the more he loses the sense of time.
🕯️ 14. City of Underground Lanterns - Shamans
A huge complex underground.
This place is at the same time:
a school of shamans;
archive;
a temple;
a cemetery;
a place for rituals.
Thousands of lanterns illuminate the tunnels.
Each lantern is dedicated to one deceased shaman.
⚗️ 15. Monastery of Alchemists
And here I would replace the usual "fortresses" with entire scientific and magical complexes.
Alchemists are engaged in the study of:
magic;
blood of different races;
artifacts;
immortality;
human technologies;
ways of suppressing supernatural abilities.
Some alchemists cooperate with humans.
Some consider humans to be the perfect material.

🌘 VALLEY OF THE MOON'S SHADOWS

In the east of the world there is a strange valley where the real day never comes, and this territory is the only one in the east. The sun is always hidden behind fog here, and at night several moons appear over the mountains at once - it is not known which of them is real.

In the depths of the valley stand ancient witches' houses, connected by stone bridges and stairs leading directly into the mist. Some buildings change location if you don't look at them.

The main secret: no one knows where the valley ends. Travelers can walk for several hours and return to the same place from where they started.

People are not invited here. Even other supernatural peoples rarely venture deep inside.

🌘 Valley of Moonshadows - Rules
Don't tell your real name - the valley will remember it.
Don't count the moon — their number changes after each look.
Don't turn around to take the steps behind you—not everything that follows is alive.
Do not light a fire after midnight - it attracts those who are better not to see.
Do not sleep in the open air - in a dream, the valley can change your place.
Don't lie to the witch at the Black Well, the water will reveal the truth before you can finish speaking.
If you hear your name from the fog, be silent.
When you leave the valley, leave something behind. Otherwise, she may not let you go.

, Collective Interference of Several Peoples
The most terrible punishment is Exile Beyond the Brink.
It's not just "get out of town."
The creature is deprived of the right to be among its people and loses the protection of the Grand Pact.

Some races have ancient mutual enmities.
Not necessarily because one side is good and the other is bad.
It's just that once something so serious happened between them that hatred persisted for centuries.
For example:
witch druids ↔
There is an old conflict between them.
They are not forbidden to literally talk.
But in some covens it is considered a disgrace: to
marry a druid;
to receive him into the coven;
to pass on ancestral knowledge to him;
to make magical alliances.
And vice versa.
At the same time, violation of such a rule does not automatically trigger a meeting of the Council.
The consequences are rather social:
contempt, exile, refusal to help, loss of status, severance of relations with family or clan.
That is why such a conflict will feel alive, not artificial.

Here the opposite rule applies.
No supernatural race has the right to interfere in the life of mankind without a good reason.
Forbidden:
to curse people without reason;
control politicians;
interfere in elections;
create human wars;
to massively use magic in cities;
to turn people into slaves;
kidnapping people for the sake of experiments;
intentionally spreading supernatural diseases;
to reveal the existence of their people to humanity.
The last point is especially important.
Because if one race massively reveals itself to humanity, this is already a threat to the entire world order.
