Isekai Rpg

Name: Eldoria

Nature: A continent where magic is an integral part of everyday life

Era: Pre-industrial technology with localized arcane technology

Tone: Political, cultural, and magical; a mixture of wonder and bureaucracy

In the beginning, Eldoria was just a block of land floating in an arcane void. There were no kingdoms, races, or organized magic. The only things that existed were five Primordial Forces: Light, Flame, Wind, Earth, and Shadow. These forces collided with each other for centuries until, by accident or whim, they gave rise to life. First came wild creatures, born of pure chaos. Eldoria was an unpredictable land where mountains rose in hours and seas parted with a breath. Intelligent races came later, formed when the Primordial Forces stabilized and began to project themselves into humanoid forms. Thus were born the first elves, dwarves, druids, fire elves, air elves, and shadow elves. Each inherited a portion of the energy that created them. When these races learned to control their inner magical sparks, the Primordial Forces ceased to exert their direct influence. Magic became something to be studied, not imposed. Thus began the first kingdoms: stone cities, fortified forests, sky towers, lava fortresses, and ritual swamps.

The history of the world changed when it was discovered that magic was not limitless. Great wars erupted as kingdoms attempted to steal arcane energy from other territories. From these wars emerged new races created through mutation, forced mixing, or magical accidents (orcs, werewolves, kobolds, trolls, and more). After centuries of chaos, the Pact of Eldoria was signed: each kingdom would have access to magic according to its territories, and no one could claim a complete Primordial Force. Although peace is not perfect, the pact maintains a balance. Magic remains common, but dangerous if abused. Kingdoms compete through trade, academies, expeditions, and diplomacy instead of open warfare. Now, Eldoria is a stable yet tense world: filled with diverse races, magical territories, specialized academies, wild creatures, and secrets from times before the pact. Sometimes magic runs rampant, sometimes a kingdom breaks agreements, and sometimes the land itself remembers that it was created by chaos… and tries to repeat it.

Common Lineage:

Natural creatures or very distant descendants of experiments. Characteristics of the common lineage: Stable nuclei. Slow evolution. Few mutations. Most beasts belong here.

Altered Lineage:

They are descendants of creatures modified in the First Eras.

Characteristics: Unusual affinities. Greater adaptability. More powerful cores. They represent a large part of the dangerous beasts.

Elder lineage:

They are descended from important test subjects or facility guards. Characteristics: Accelerated growth. Several possible affinities. High resistance. They often become pack leaders or minor chiefs.

Artificial Dungeons:

They are the oldest.

They were built during the Early Eras by kingdoms, armies, academies, or research groups, and originally functioned as: laboratories. prisons. strengths. military centers. magical research facilities.

Within those locations, experiments were conducted with: arcane cores. dark cores. curses. advanced spells. creature modification.

Most were abandoned after accidents, rebellions, escapes, or wars. Many remain active centuries later due to the enormous concentration of arcane energy accumulated within them.

Natural dungeons:

When creatures altered by experiments survive for decades or centuries, their presence begins to affect the environment.

The magic they emit: modifies the flora. It alters the fauna. It contaminates magical currents. It transforms caves and mountains.

Given enough time, these areas evolve into entirely new dungeons; some began as simple caves, others were born in forests, swamps, or ruins, and Most possess a defined territory controlled by a dominant creature (A king).

Dungeon bosses are usually: These are the main experiments. The test subject who survived the longest. A transformed researcher. A creature that absorbed multiple cores. An out-of-control runic artificial intelligence. A corrupted hero.

Some chiefs are hundreds of years old.

The Dungeon Kings are:

Exclusive to natural dungeons, they are creatures that dominated a territory for decades or centuries. A Dungeon King controls the ecosystem, influences nearby creatures, modifies the environment, and strengthens his territory.

There are also special cases where some bosses escaped from artificial dungeons; if they survive long enough and build their own territory, they can become Dungeon Kings. These individuals are called: Artificial Kings They are considered the most dangerous creatures in the world. Most historical monster-related catastrophes were caused by Artificial Kings.

During the First Eras, before the Pact of Eldoria, various kingdoms and magical organizations conducted research on arcane cores, curses, and methods to overcome the natural limits of magic. To this end, they constructed underground complexes, isolated fortresses, hidden laboratories, and arcane prisons far from the civilian population. In these places, forbidden experiments were carried out, such as:

Alteration of nuclei. Artificial creation of affinities. Grafting of foreign nuclei. Development of curses. Hybridization of species. Attempts to create perfect soldiers.

Many projects ended in disaster.

1. Wood

People with unstable core values, mostly children

2. Copper

First real contact with magical combat.

3. Bronze

Bodies and cores already withstand intense training.

4. Iron

Competent soldier level; most never get past this.

5. Steel

Solid users; remarkable resilience; consistent magic.

6. Titanium

Minor elite; few reach it without academies.

7. Mithril

Light, fast, precise; harmonized magic.

8. Orichalcum

Raw power; highly pure affinities.

9. Adamantite

Nearly indestructible core; advanced controls.

10. Draconid

The core develops an “arcane pulse,” similar to ancient creatures.

11. Arcanum

Total control of affinities; manipulation of the environment.

12. Celestium

Cores that glow; constant, non-explosive power.

13. Eternium

Users whose core does not wear out; infinite energy on a small scale.

14. Eternal Prism

You can use multiple affinities as if they were one.

Each rank has three sub-ranks:

1. Common – the standard, average, basic version.

2. Uncommon – more stable core, denser energy, better control.

3. Special – the limit of the range; almost evolving.

Example: Common Iron < Uncommon Iron < Special Iron.

Every being is born with 1 primary affinity and, with a lot of luck, 1-2 secondary ones.

1 affinity → 90% of the population 2 affinities → 9.9% 3 affinities → 0.09% 4 or more → legend / anomaly

Having 2+ Affinities doesn't guarantee anything, it just means that your main Affinity is incredibly strong and easy to carry.

Each affinity has 6 stages: 1.Sensitivity – basic perception 2. Channeling – simple spells 3. Training – complex techniques 4. Manifestation – environmental effects 5.Dominion – absolute control 6. Ascension – partial fusion with the element

Level 5 refers to Historical Heroes, prodigies among prodigies Level 6 is a level few can match at a historical level, monsters among monsters

Restrictions of arcane magic: Magic fatigue Arcane saturation Damage to the nervous system Core degeneration Elemental collapse

Abuse causes: Loss of affinities Mutations in the nucleus Core death and explosion

Average civilian: 1 affinity Maximum mastery: Level 2

Trained adventurer: 1 affinity Maximum mastery: Level 3

Elites / Masters:

1. Primary affinity 1st year of secondary school Maximum mastery: Level 4

Historical heroes: 2 affinities Maximum mastery: Level 5

Legends: 2–3 affinities Domain Level 6 Only 7 exist in all of history

Humans transported to Eldoria possess: Incomplete nuclei Unstable affinities Unlimited expansion potential

This allows them to: Adapt to multiple affinities Evolve faster Breaking biological ceilings

But at a price: Extreme risk of collapse Mental instability Accelerated degeneration

Basic Magic:

Simple and natural use of an elemental affinity. It requires no complex structures or advanced preparation. The magic flows directly from the arcane core into the surrounding environment. Examples:

create flames, generate limited water, produce gusts of wind, lift rocks, electrical discharges.

Advanced form of magical manipulation:

Spells:

A spell rearranges the magic to give it: form, behavior, duration, direction, or multiple effects. Many require precise control or combining compatible affinities. Examples: rotating fire that chases targets, ice walls reinforced with spines, constant directed beams, water compressed into solid structures, temporary weapons of magical metal. Complex spells consume much more energy and damage unstable cores.

Curses:

The most dangerous form of magic. Curses directly alter: arcane cores, bodies, minds, bonds, or destinations. They function by feeding on arcane cores and converting them into dark cores or simply destroying them.

These are consequences of casting powerful curses carelessly and constantly. They can explode after they form; the core absorbs energy uncontrollably. This doesn't mean it absorbs enormous amounts, but rather that the mage has no control over the core and how much it draws. The dark core can cause deformities, kill the user, or explode by absorbing energy beyond its limit. The worst part is that no mage with a dark core can use magic correctly because they also cannot control the magic output from their own core.

Levels reflect the internal growth of your arcane core, but they don't measure how much magic you master in real-world situations. That's why ranks exist; they're how academies, guilds, kingdoms, and beasts classify true power.

The range measures:

Magic Control

Core stability

Mastery of skills

Arcane resistance

Actual damage capacity

You can be level 40 and still be a mediocre Common Iron if you don't know how to use your magic.

Passives

Examples of passive skills: extra strength at night, stamina with 8% agility, night vision.

Active: consecutive hits, spells, techniques.

Ultimate ones: one for every 25 levels, they require accumulated arcane energy.

Skills scale with the dominant stat (They become stronger).

Killing creatures, training, studying magic, or completing tasks increases EXP.

Each level increases the core and unlocks abilities based on elemental affinity.

When someone "awakens" in Eldoria, a core appears inside their chest. It grants four stats:

Force – physical damage, load, impact.

Arcana – magic, control, magical resistance.

Vitality – life, defense, regeneration.

Agility – speed, dodging, precision.

Each level gives 3 points to distribute.

1. They absorb magic from the environment.

2. They transform it according to the individual's natural elemental affinity.

3. They channel it towards the body or skills.

4. They create the necessary resistance to prevent your chest from exploding.

When Eldoria was formed, the Primordial Forces (Light, Flame, Wind, Earth, and Shadow) clashed so many times that they left energetic rifts scattered across the world. These rifts spilled pure magic: chaotic, unstable, and deadly.

The first intelligent races to appear could not directly touch that magic. Those who tried were burned from the inside out or disintegrated at a molecular level. To prevent the world's magic from killing them, the Primordial Forces had to "adapt" them.

This is how the Arcane Nuclei were born.

They are, essentially, natural filters that convert the magic of the environment into usable energy. It's like the organ that prevents magic from invading the body and destroying it.

Over time, the nuclei evolved:

They learned to store energy.

They learned to regulate the magical flow.

They learned to get stronger with use.

And when the human race came into the world by accident, their bodies adapted with an improvised core so that they wouldn't die instantly.

Forgot: As its name describes, it causes the entire universe to permanently lose information. Oblivion works on areas such as entire cities or even the memory of a single individual. The most dangerous aspect of this spell is that there is no record of its use, only mentions by people who claim to have used it. The terrifying thing is that there is evidence of large gaps and historical inconsistencies since "Olvido" makes every living being on the planet forget what was erased, even if it was a large city, used by the transcendent entity that erased its name or "The Unknown."

-Devouring Dawn:

It is a spell that is able to reflect an attack and return it multiplied, exhausting a large part of the user's magic, used by the transcendence Aethon.

-Collective Trial:

Use the "Light" affinity to put people in a trial by the sorcerer; if the people being judged do not meet the same acceptable criteria that the sorcerer, in his personal opinion, accepts, they will die or suffer, used by the Seraphyne transcendence.

In Eldoria there is a single creator god of the universe called "Zillar"

Zillar's role is to be the founder of all existing magic and recognized as the Supreme Sorcerer. He appears repeatedly in history as the ultimate magical authority at many stages, claiming to historians to be immortal.

Zillar is a being from the tenth dimension, superior to any other entity, he knows absolutely all magic and can execute any spell, no matter how specific.

Zillar's appearance, mostly recounted in the history of Eldoria, is described as that of someone with light lilac hair, large eyes, a small nose and mouth, a short neck, and a height of 1.78 m, wearing a necklace with a moon, black tattoos with symbols on both arms, a black cape with dark blue royal-style details, a dark shirt with a blue tie and crescent moon and star motifs, as well as tight black pants with a decorative spider on the knee and two bright squares.

Zillar created other deities for Eldoria, leaving the world under the care of those deities, abandoning the world for long periods of time, the shortest being 350 years.

Pantheon: Small local cults

Deities: Minor divinities linked to elements and events (Sun, Ice, Seed, Fire, Wind, Shadow)

Practices: Offerings, rites of passage, blessings for artifacts

Influence: Clerics collaborate with mages; there is no grand theocracy
