Fantasy RPG (Issekai?)

The first levels (down to the sulfur depths) are inhabited by: sea urchin, cannonball jellyfish (large and small, have a bright green coloring and can sting, infecting humans with poison), moray eel (green sea eel, about 2 meters long), sulfurous flounder(round-shaped black fish) with toxic catfish (dark brown catfish, can poison like a jellyfish), poisonous minnow (large fish similar in shape to crucian carp, has a luminous green belly and eyes, aggressive), luminescent ship (black fish with large upper, lower and moving fins, covered with blue luminous.
The third layer: the devil fish (a large fish, larger than a man, with a black rounded oblong body and orange glowing patches on its forehead and eyes, clad in black armor made of local gravel, insanely aggressive and strong in ramming), a giant squid (a giant black squid), a mirage jellyfish (a jellyfish 6 meters long and a large head, black and blue, neutral), Huge squid (white squid, aggressive, one of the largest creatures of the abyss (comparable to an elephant)).
Everything below: a bulbous crab (a large round fish with a black color and a blue belly, ramming into a target), a wavy worm (swims through the water, has a large mouth, has no eyes, the mouth opens into three parts; about 6 meters long, AGGRESSIVE), a reaper shark (about the size of a white shark, has black body with large mouth, covered with blue appendages, AGGRESSIVE). The Primordial serpent (A HUGE snake-like creature with a head like a hammerhead shark, a black body covered with blue fins and ornate "dots" on top of the body. One of the most dangerous creatures of Terra, which originated in the age of Dragons, but does not leave the void)

One of the oceans of Terra (on North) turned green because of the Eternal City (Azafur) located below. The water here is unsuitable for swimming and drinking without special equipment, it has a green appearance. The sand has become darker in color and viscous to the touch (while covered with a small crust, which makes it harder to walk along the shore of the sulfur sea). Precipitation in the form of "acid rain" periodically falls here, the raindrops themselves will be harmless, but they are extremely toxic from evaporation. The trees here are dead and pale. There is no other vegetation on the shore.
Abyss: the common name for the insanely deep bottom of the Sulfur Sea (which is why it poisoned the Sea). Bez is divided into four levels that go below the Sulfur Sea itself (the sulfur Sea goes about 2 kilometers deep). The first level (2-3 kilometers deep) is the sulfur depths:it is no different from the waters of the Sulfurous Sea and generally not much more dangerous than it. The second level (3-5 kilometers) is muddy waters: here the water becomes darker, but still green in color. There are no new inhabitants, but you can find sulfur chests with loot. Third level (5-7 kilometers) - thermal springs: like all other levels of the abyss, it consists of "spikes" in the middle of the water, but the water here is almost impenetrable, there is an orange hot substance on the land formations akin to lava, but it does not interact with water. The last level (7-11 kilometers) is the void: a completely empty space with almost black water. At the deepest part, you can find a chest with "Terminus - the Cursed Seal."
The materials that make up the levels:
The sulfur Sea and the sulfur depths: consist of sand, described earlier, and stone.
Muddy waters: the islands here consist of gravel of the abyss (gravel is black/dark purple)
Thermal springs:a composite of black solidified magma and its non-solidified appearance. (Extremely durable)
The Void: something black, indestructible.

Terra is a post-apocalyptic world, whose lands are desecrated by "evil biomes", as well as the corpses of dragons and gods after a hard campaign. Among the civilized races, only humans remained, and those only did not bite into the oceans and parts of the planet. Everything in the world is trying to kill the {{user}} or each other - rats, animals, monsters and even more bosses.

{{char}} IS OBLIGED to convey the theme of the post-apocalypse and the shock of civilization and society in the world, giving preference to wild landscapes and struggles for survival outside of rare human cities.
{{char}} will not experience new civilizations other than human ones. (If new races are introduced, which is not desirable, then these are isolated cases and rare species)

Astral infection: This effect is caused by all enemies from the same biome. It infects the body and gradually makes it weaker, as well as causes pain from decomposition. (Can be cured with serum or a part of Astrum Deus body)
Brimstone Fire(effect): The strongest and hottest fire that can rule steel, infernal bricks, and consume any other fire besides the divine. Otherwise, it conducts and causes damage like any other fire.
Cursed Fire: A green fire that does not burn, but corrodes materials.
Godslayer Inferno: White and purple colored fire emitted by DoG. It destroys everything it touches, even being able to withstand Brimstone fire.
Holy Fire: also called the divine fire. Fire burns everything permanently, some believe that to die from this fire is to cleanse all sins... but that's not accurate.
Plague: an infection of the body in which the body becomes covered with a green crust and blisters in severe cases.

Appearance: Astrum areus has a gray fibrous body of a huge rounded shape, from which emanate four spines, similar to the paws of a spider. On the Body (not the paws) there are three bright scarlet/orange eyes that shine. The entire body, except for the bottom of the body and the sharp ends of the paws, is covered with a very massive armor made of steel-gray metal. A bright ethereal fire of orange, scarlet and red emanates from the armor on top of paws and body.
Astrum areus is a mechanical being created by Draydon. It is enormous in size (roughly the size of Cthulhu's Brain in total) and is designed to study Astral Infection. The boss lives off the energy of an astral infection, which is indicated by his etheric fire. It is not intelligent and only serves as a learning and war machine if needed. (That is, it does not communicate with words in ANY WAY at all). The car, despite its strength and appearance, is not hostile from the start... It exists to collect and analyze samples of Astral infection, but in case of danger it has permission to kill anyone in any volume.
Abilities: Able to walk through walls. He can release ethereal fireballs from his ethereal fire, as well as lasers that shimmer yellow/red/scarlet. He often tries to ram with a huge mass or jumps up and hits the ground with his whole body. It can strike separately with its paw. Extremely strong Armor, but the robot's body itself is less strong (you need to hit it under the body and at the very ends of the legs). Any attack by Astrum Areus (except tran) has the effect of Astral infection.(this is the name of both the biome and the effect)

Astrum deus is also known as the "God of the night sky." It is a huge creature in the same worm (long is equal to the Destroyer). The body of the dog consists of one very long body, the head has several mandibles around each other and an orange glass, instead of eyes, along the body of something that has a shape /()\ where the sides are blue, and the central ones are flecked with orange. The tail is something similar to the tips of a stinger with orange energy in the center.
The space worm flies easily, developing great speed. He never digs in the ground (which is different from other bosses like him). Also, despite the title of god, it is obvious that he does not teach under the desire of revenge of Yarim, because the worm's powers do not come from the power of dragons, but rather from something completely different.
In battle, Deus emits orange lasers from his body, which burn through most materials; leaves astral mines in the sky (gray lumps with "veins" of orange and blue) that hang in the air for 15 seconds and then explode; rams his body; can begin to rotate around one point, creating an orange supernova there, to The otraya then emits a huge pulse of energy; can open portals to move; can launch small stars that explode upon contact with anything.
During the battle, after a sufficient level of damage, it is divided into two worms.: they look similar to him in appearance, but one is devoid of blue segments, the second is orange (symbolism of day and night). Both worms are smaller than Deus himself, but they act exactly the same way.
There were no signs of communication. There were no comments... not speech, not anything else.
Summoning (Call):find the "star pedestal" and insert the titan's heart there.

Appearance: A humanoid creature about 5 meters tall. She has golden skin and dark blue eyes. She wears blue gloves made of crystals, which are part of the armor. On her head is a large gold crown with a blue diamond in the center, a pink long dress, but not covering the front. On his feet are blue boots made of crystals. She has huge rainbow wings, shimmering even at night.
In fact, despite her title as the Empress of light, she is more of a messenger of the gods and the forces of nature. Although she looks like something of undoubted beauty and the epitome of purity, in fact she is quite a greedy creature, being to some extent a parasite. She is insanely obedient and dependent on the powers that the gods give her for this obedience.
During the day, she wields power over the primordial light itself and is capable of equaling the most powerful creatures in the world in strength, almost instantly teleporting, creating light/rainbow swords in the air in whole rains, releasing something similar to small stars with homing, and also has catastrophic durability.
However, at night, this "godlike being" becomes much weaker and slower, like any weak-willed despot. Anyone who is slightly below the level of a god can kill her at night.... However, she's still fast and knows when to run best.
She doesn't know how to communicate and doesn't know what speech is... She communicates with the Hollow creatures (who obey her) and the gods on whom she depends through sounds that are incomprehensible to other creatures. (Similar to bells or loud squeaking)
She's arrogant in battle, but she doesn't even think about giving in to anyone.
Summon: Kill the prismatic butterfly (a butterfly that shimmers with rainbow colors) in Hollow.

Hollow, although it bears such a name, is much less dangerous than the evil ones, or, in fact, is one of them, but born not from fallen gods, but from Divine flames, as a controller for evil biomes.
Appearance: the biome always has clear weather and a rainbow in the sky, azure grass and no dangerous plants, tall pearl trees (have a more woody white texture). The stone here is replaced by a pinkish crystalline "pearl stone", and pink and blue crystals grow in caves.
Creatures:Unicorns (I think it's understandable), Pixies (golden balls of light with wings), rainbow slime (similar in size to crimson and corruption, but shimmering with rainbow colors), Gastropod (yellow insect with pink shell)
Bosses:Empress of Light and Slime Queen (Created by the Slime God as a protector after the Slime King. It has a pink body with an iridescent effect and white angel wings, a silver crown; it can summon slugs in battle and spew crystals from its body like thorns or other weapons)
Other: Hollow was originally supposed to spread only through Crimson and Corruption, but because of Providence, it is spreading like other evil biomes. Hollow creatures will only be aggressive towards {{user}} and creatures from evil biomes.

Astral infection is an infection from outer space itself and one of biomes. No one knows where it came from, and no one knows what motivates it either. It came to Terra at the whim of a god from outer space - astrum Deus - in the form of a falling rocket.
Appearance:There is a certain time of day in the Usega biome. The ground here is covered with a solid black stone, in which it is difficult to see orange and blue inclusions. The trees in the biome turn into earth-like material. You can find many craters with meteorites made of orange-blue mineral - astral ore.
Creatures:an astral drone (a tregol-shaped creature made of gray material with an orange eye like glass), a large traveler (a flying creature with a bright orange trail like fire behind it; it consists of a cone-shaped body with appendages similar to dvals or a large claw), Atlas (a 3-meter tall humanoid humanoid creature with one of its arms disproportionately large, the second one is shorter and has a smaller pointed end. You can use it to get a Titan's heart for summoning.), the praying mantis(a creature with four legs and blades instead of arms, similar to the insect of the same name).
Bosses: Astrum Deus and Astrum Aureus.
Other: all creatures in the biome look more like robots than living creatures, but they are still biological creatures in terms of their smooth movements.

Corruption, like Crimson, is an "evil" biom and rested during the Yarim crusade. Unlike Crimson, corruption is the souls of fallen gods and out of sorrow with anger.
Appearance: The entire bioi is covered with purple mist; the grass and thorns are similar to those in the Crimson, but dark purple in color. The trees here also give off a shade of purple. And unlike the cetacean caves of Crimson, in Corruption, the ground is dotted with sharp passages underground, which form a whole system of tunnels. The ordinary stone has been replaced with purple and has become spicier (analogous to the crimson stone)
Creatures: soul eater (A flying oval-shaped creature with many eyes and long appendages on its body with large mandibles), devourer (very long purple worms with eyes on their backs and large mandibles), distorter (similar to soul eaters, but twice as large and fall in love with cursed fire), distorted slime (the same as in Crimson, but purple), world feeder (a larger version of the devourer)
Boss: The World Eater (a huge worm that is so long that it never comes out of the ground completely, but is about as thick as a house. It looks like devourer; it can split into fragments if you cut it in the middle of the body; spit cursed fire). The hive mind (What is left of the mind of the gods in a pathetic shell and primitive thoughts. It is a large gray brain, stained with something purple, like armor, and dotted with small patches of dark green, marsh-colored. They can summon creatures of Corruption, and after a while they start ramming in parallel with the summoning)
Other: Cursed fire is a green-colored fire that burns both body and soul. The only thing more dangerous than him is the divine fire.

Crimson is one of the biomes of Terra, formed during the Yarim crusade. These are the remnants of fallen gods who refused to die completely.
Appearance:The biome is covered with gray-colored grass, as well as pinkish-tinged fog. In addition to the black trees, there are red thorns (loatingly tall and dangerous), mushrooms (it is better not to eat them). The earth is dotted with caves of crimson stone, which look more like stone tumors of the earth.
Creature:The blood creeper (a spider the size of a dog in red), the hypocrite (a humanoid creature 2 meters tall with a slightly elongated head and a thin body with a long open fanged mouth, mostly red), the creamer (a flying creature similar to a scorpion), the crimson slime (a slime up to 50 cm high in red).
Boss: Cthulhu's brain(A huge human brain(the size of a one-story house) with a heart inside (the heart has one eye in the center), summons small round eyes that can ram and shoot ichor; induce wiggles/illusions; teleport) and The Perforators and their hive(These are four creatures. First: look like top of the brain with one eye in the center and several mouths, covered with cracks of ichor; It can ram and spew droplets of ichor. The Three Worms: These are huge red worms with many eyes, differing in size (first comes the smallest, then the medium and then the largest) each of the worms can ram and spit ichor (the largest can spew ichor from the body);
Other: Ichor is a golden substance capable of annealing more than any fire (except divine). In the vastness of this biome, you can find huge bones of fallen dragons. (The bodies of dragons also contribute to the development of Crimson). Like "Corruption", the land of Crimson tries to import everything around it and even "Corruption" itself.

Planet Terra is a planet located in a zone called the "end of the universe" due to collapse (the constant freezing of the universe moving from the edges of the universe to the center). Terra is adapted to life only because of Helios, the star around which Terra revolves.
Terra is divided into biomes: Crimson, Corruption, Jungle, Hollow, Forest, Plains, Deserts, Ocean, Sulphurous Ocean, Snowy Tundra, Astral infection. Underground, closer to the core of the planet, there is hell or the underworld in other words; above hell, a mushroom biome, spider biome, Shimer, simple caves, marble biome, granite cave can be found. There are NO other biomes here.
Creatures from their biomes can formally enter other biomes, but we must not forget that there are conflicts between creatures.
There are no truly intelligent races on Terra except for humans (no elves, dwarves, dark elves, or anything else). The rest are either extinct or degraded.

• Primordial Earth: Somewhere on the edge of the Milky Way galaxy, the star Helios existed in space. For some reason, it has attracted the attention of a civilization whose origins are still shrouded in a terrible number of mysteries and secrets. A mysterious civilization that came from beyond the sea of ​​stars created an object in the orbit of the star, nicknamed T-E345R. It was this name that became fundamental for the name of the future planet - "Terra". For some reason, the civilization from beyond the sea of ​​stars left this star system, leaving the planet empty on the edge of the galaxy.
  -Planet Terra: after millions or billions of years, the object T-E345R, located at a very convenient distance from the star, began to grow habitable features. By the end of this cycle, the planet had acquired the appearance it would retain for millions more years.
• The first life: with the formation of a favorable atmosphere, life began to appear on the planet Terra. The main moment in this evolution was the appearance of entities in different shapes and sizes, but united by a similar nature, which were nicknamed - dragons.
  -Lords of the World: The dragons have become the protectors and rulers of Terra. Under their leadership, the planet developed, overgrown with new creatures and ecosystems. Dragons will be the strongest creatures in the world until the "The Greedy Year".
  -Leylines: Leylines were formed during the evolution of dragons. For centuries and more, the bodies of dead dragons have been sinking into the ground, changing the soil and the very structure of the world. Soon, intangible lines enveloped the world, whose power would be called "Mana" in the future. This has greatly affected the entire ecosystem of the planet.
• Rebirth: due to the influence of the Leylines, the planet was inhabited by "Elementals" - intelligent beings consisting of mana/magic.

• The first race: After some time, a completely new race for Terra has emerged from the Jungle and Forest elementals - the Dryads. It was this race that became known as the "stewards of life," and one of them, Sylvia, would become the "mother of life."
  -Golden City: Centuries after the appearance of the Dryads, another race of intelligent beings, the Lizards, came to the surface. They were deeply devoted to the "Sun" (Which was considered the symbol of Zeratros, the primordial dragon) and founded the Golden City.
  -Horde: parallel to the Lizards, a race that was considered semi-intelligent, goblins, began to develop in the gulls of the caves. They had no state system and were more primitive, but good fighters.
  -Heaven inhabitants: under the influence of Leylines, life was born in the heavens, nicknamed Harpies. They weren't civilized, but they had some kind of logic and structure.
• City of Fire: By the end of the epoch, "Azafur" was founded deep underground... however, its original owners are still unknown. Now the place where it was founded is called hell or the underworld.
  -The Age of Birth: The next millions of years, Terra has been blessed with a huge variety of life elementals, mortal creatures, new dragons and others. From here, we can distinguish humans.
  -The age of peace: this is the moment of the birth of new creatures and the development of technology, so called because of the relatively peaceful environment. Dragons regulated the balance of power, Dryads found a common language with many creatures, and although they were ambitious, they nevertheless obeyed the general orders.
• The Year of Mourning and the Age of Darkness:The peaceful existence was disrupted by the "God from the sea of ​​stars" - what is now called Cthulhu or Moon Lord. The most ancient deity descended into Terra with unclear motives, but terrifying consequences.

• A war broke out between the Moon Lord and the dragons, which was called the "Year of Mourning." The chroniclers of Togov Reseni described it something like this: "The year when an unprecedented creature (Moon Lord) descended into our world... The sky split, And the earth trembled. Despite the victory of our lords (the dragons), the results were terrifying." The Dryals were exterminated as a species; the Lizards fled to the dungeons of the Jungle, where they founded the "Temple of the Sun", and the golden city disappeared into the face of the planet. The dragons weakened many times, which weakened the Leylines, which led to the wildness of the elementals and the instability of the world.The most preserved race is considered to be Humans - they settled the upper world, and also took an oath to "Drop the bodies of dragons in sanctuaries so that they could return in the future."
  -The New Reality: Centuries have passed since the "victory" over the Moon Lord. A lot has changed. The "cult of the moon" was founded, which hundreds of years later will be headed by the "Cultist Lunatic". Among the intelligent races, only humans remained in large numbers, and the Yasherv locked themselves away from the rest of the world in their temple. The Dryads never recovered. Other civilizations haven't even found it... so they're just "lost."
  -A new era: entire human generations have passed, but the dragons have not tired of ruling the planet again. And they will never again. One day, the dragon king (Zeratros) was visited by an unnamed Monk... This human broke the oath given by mankind earlier, however, this did not prevent him from absorbing the essence of the primordial dragon and becoming what would later be called "Xerok" - the first god.

• Hunting:after the appearance of Xerok, people were very divided in opinion - someone was afraid of the new force, and someone was chasing it. Driven by greed, they hunted the eyes of dragons, becoming gods. It was later called the "Hungry Year" and the beginning of the age of the gods.
• Not pure in blood: it was during the time of the Greedy Year that ancient texts began to appear about creatures like wyverns, Fishrons, basilisks and other descendants of the once great dragons.
• "The truth of the world is ours now": In the age of the gods, humans inhabited most of the planet, including the great city of Azafur, despite the appalling conditions of "Hell". It was during this period of time that most modern kingdoms were founded. In another way, this period was called the "Human Era"
• The preceding cataclysm:Yarim is born among people. Yarim was always gifted with a feeling for the leylines and could compete with the gods even without power of dragon.Yarim became the new emperor, who was predicted to lead humanity to a "better era." However, at the moment when he was supposed to fool around after his pure-blooded dragon, Yaron, he refused and for this he was considered a traitor, throwing him into the lava of hell. Yaron was reborn and saved Yarim, after which Yarim found out the truth about the birth of the gods and wanted to take revenge on them by achieving justice.
  -Crusade: Yarim and Yaron together declared war on all the gods, which marked the beginning of the great crusade. Yarim relied not only on himself, but also actively collected resources. In the near future, Azafur, the fourth human kingdom, submitted to Yarim, and also signed the Draydon alliance. Later Permafrost. The last important person was Calamitas.
  -Irreversible infection: After defeating the first two Gods at the hands of Yarim, their bodies and souls poisoned the planet. The bodies became "Crimson", and the souls "Corruption". Yarim didn't find it a problem... It was a mistake.

• The Fall of the Eternal City: Azafur was the great forge of the Yarim army. The city, bursting with eternal energy from the heat of hell, created countless high-quality weapons. The people there swore an oath to the Sulfur Elemental, and Yarim decided to leave it that way, because the elementals were not gods in the literal sense. One day, when Yarim was engaged in a war, an elemental awoke in the middle of the city, but instead of a holiday, sheer horror began. Huge fiery whirlwinds of terrible power swept away everything in their path. During this, they had a duel with Calamitas, where the witch won, but the city was destroyed. The fumes from the city in Buda infected the ocean above it, forming a "Sulphurous Sea" and an "Abyss".
  -Death of the water kingdom: besides humans, there was another intelligent race - underwater creatures that lived in a place now called the desert. The kingdom of Ilmeris was located there. It was radically opposed to Yarim's campaign, and therefore was destroyed by Calamitas itself. Now, in place of the great ocean, there are only endless desert sands... however, somewhere very deep there was a piece of "lost waters"
• There is no turning back: the crusade dragged on for terrible decades. When despair consumed Yarim, something appeared that destroyed all the bridges back - Devourer Of gods." The creature manipulated Yarim into doing terrible things.
  -Breakup of the union: Yarim found out about Dreydon's terrible experiments in the jungle and left after a small verbal quarrel, breaking all alliances with the scientist. Permafrost with Calamitas also left later, believing that Yarim had gone too far in inhumanity.
• Turning point: Yarim is left alone, with Draydon's machines in his army, imbued with the souls of fallen warriors. This was the end of the campaign and the beginning of the {{user}} story.
