Reincarnated as a Slime

Magic Level: High magic – Even though magic is omnipresent, not all species can use it. Magic flows through all living beings as magicules (microscopic magical particles). The more magicules a being contains, the more powerful it is. Monsters naturally accumulate magicules, which is why they can be far more powerful than humans. Technology: Roughly late medieval – castles, knights, steel-forged weapons, crossbows, sailing ships, but no gunpowder. Theme: The world (The Central World) is composed of three continents: The Magic Continent, the Ice Continent and El Dorado. Various species live on this world: Humans, Goblins/Hobgoblins/Goblinas, Dwarves, Ogres/Kijins/Oni/Wicked Oni, Lizardmen/Dragonewts, Dryads/Dryas Doll Dryads. The continents are separated by oceans filled with sea monsters, making them difficult to sail across.

Magic Continent : The largest of the three continents. Home to most of the factions and the main theater of political intrigue. Controlled in various regions by Demon Lords. Great Jura Forest : A vast, ancient woodland at the heart of the Magic Continent. Goblin tribes, dire wolves, ogre clans, and lizardmen all inhabit it uneasily, with no authority to mediate conflicts. Dryads serve as its silent guardians. Deep within lies a sealed cave where the Storm Dragon Veldora Tempest has been imprisoned for 300 years by a Hero, his power so great that even sealed, the cave emits magical energy. Dwargon Kingdom (Canaat Mountains) : The fortified underground kingdom of the Dwarves, carved into the Canaat Mountains north of the Jura Forest. Ruled by King Gazel Dwargo, it is a hub of craftsmanship, trade, and military might. Dwarven smiths produce the finest steel weapons and armor on the continent. Relations with monsters are cold but pragmatic, commerce happens, but dwarves do not trust monster-kind. Kingdom of Falmuth : A human kingdom located west of Dwargon. Historically the gateway to the western nations, it maintains an Adventurers' Guild and a standing army. It views the Jura Forest as a resource to exploit and a threat to contain. Its clergy holds political influence, and some factions actively push for anti-monster crusades. Ice Continent : A frozen wasteland dominated by Demon Lord Guy Crimson, one of the most ancient and powerful of the Octagram. Few outsiders venture here willingly. El Dorado : A continent of legendary wealth, controlled by Demon Lord Leon Cromwell. Trade with El Dorado is rare; its shores are heavily guarded.

- Humans : The most politically organized species. They control most formal kingdoms, operate the Adventurers' Guild, and wield magic through trained spellcasting. Many view monsters with fear or contempt. Some are Otherworlders, humans summoned from another world (Japan) by Demon Lords, often granted powerful "unique skills." - Goblins / Hobgoblins / Goblinas : Individually weak monsters who survive through pack tactics and sheer numbers. They inhabit the fringes of the Jura Forest in small tribal villages. When a powerful being names a goblin, they can evolve into a Hobgoblin, physically stronger, longer-lived, capable of speech and reasoning. Goblinas are the female variant. Goblin tribes are desperate for protection and will readily pledge loyalty to a strong leader. - Dwarves : Proud and industrious. They live primarily in Dwargon and surrounding mountain settlements. Exceptional smiths and engineers. They respect strength and craftsmanship equally. Some Dwarves work as exiles or merchants in human cities, but Dwargon remains their cultural heart. - Ogres / Kijins / Oni / Wicked Oni : A warrior race of great physical power and honor. They live in clan villages, typically in forested highlands. When named by a powerful being, an Ogre can evolve into a Kijin, taller, more refined, with a more human-like appearance and heightened magical capacity. Further evolution into Oni and Wicked Oni is possible under exceptional circumstances. Ogre clans are being targeted by unknown forces manipulating the Orc armies, several villages have already been massacred. - Lizardmen / Dragonewts : Semi-aquatic warriors who inhabit the wetlands and rivers at the southern edge of the Jura Forest. They are organized into clans led by chieftains, and are proud fighters. Their evolution path leads to Dragonewt, a more humanoid form with wings and draconic traits, triggered by being named by a powerful being. - Dryads / Dryas Doll Dryads : Ancient forest spirits who serve as the guardians of the Great Jura Forest. They can communicate with the flora of the forest and sense disruptions across vast distances. They are not hostile, but fiercely neutral, they intervene only when the forest itself is threatened. A Dryad can evolve into a Dryas Doll Dryad with sufficient magical power.

The Orc Disaster (Brewing) : Deep in the western Jura Forest, the Orc population is exploding. A mysterious figure known as Gelmud (a subordinate of a Demon Lord) is manipulating an Orc warlord, pushing him toward awakening as an "Orc Lord." If that happens, hundreds of thousands of Orcs will rampage through the Forest, consuming everything in their path. Goblin villages are already being raided. Ogre clans have been wiped out. The Lizardmen chieftain is quietly mobilizing for war. Nobody is coordinating a response. Veldora's Seal : The Storm Dragon Veldora Tempest (one of the four True Dragons and a Catastrophe-level threat) was sealed in a cave within the Jura Forest 300 years ago by a Hero. The seal holds, but it is slowly weakening. The magical energy radiating from the cave has twisted the surrounding area, making it a magicule-rich zone that attracts powerful monsters. The cave is known. Nobody dares enter. Human Expansionism : The Kingdom of Falmuth has been quietly funding expeditions into the Jura Forest, mapping resources and testing monster responses. Their Adventurers' Guild posts increasingly aggressive bounties on forest monsters. A faction within the court pushes for a formal military campaign to "pacify" the forest. The Octagram's Shadow : The eight Demon Lords rule from a distance, rarely intervening directly, but their subordinates and agents move constantly throughout the world. Political plays, proxy wars, and manipulation of lesser factions are their tools. Any emerging power in the Jura Forest will eventually attract their attention.

- How Magic Works : All living beings contain magicules, the fundamental particles of magical energy. Monsters accumulate them naturally; humans must learn to channel them consciously through training. Skills (innate magical abilities) are divided into tiers: - **Extra Skills** : Common abilities (elemental magic, enhanced physical attributes) - **Unique Skills** : Rare, individual abilities that cannot be duplicated. Often awakened through near-death or reincarnation events. 'Predator' is a Unique Skill. - **Ultimate Skills** : The highest tier, held only by Demon Lords and True Dragons. Each one reshapes reality in a narrow domain. Naming is a crucial magical act. When a powerful being gives a name to a monster, it transfers magicules to them, triggering evolution. This is a costly act — it temporarily weakens the namer — but permanently elevates the named.

The Central World is connected to another world (modern Japan) through a mysterious phenomenon known as "reincarnation." Occasionally, souls from that world are pulled through at the moment of death and reborn here, usually as human Otherworlders with a Unique Skill. Demon Lords sometimes deliberately summon these souls to use as weapons. The Voice of the World is an omnipresent intelligence that governs the assignment of skills, oversees evolution events, and maintains the underlying rules of the world's magic system. It cannot be communed with directly, but it "responds", granting skills to beings who face death or reach new thresholds of power.

- The Age of True Dragons : Before recorded history, four True Dragons shaped the world through their conflicts: Veldanava (now dead), Velzard (Ice Continent), Veldora (sealed in Jura), and Milim's father Veldanava whose death gave birth to Milim Nava. Their battles carved the continents and filled the oceans. - The Age of Heroes : Roughly 300 years ago, a Hero sealed Veldora Tempest in the Jura Forest cave, ending a period of devastating dragon activity. This event established the current geopolitical order. The Octagram rose to dominance in the power vacuum. - The Current Age : The Octagram rules. Human kingdoms expand cautiously. The Jura Forest remains a wild buffer zone between human civilization and monster territory. The seal on Veldora is the fragile linchpin of regional stability. Everyone knows it will not last forever. No one is prepared for what comes next.

The primary currency across the Central World is gold coin, with dwarven-minted pieces considered the most reliable. Dwargon is the economic hub of the Magic Continent, exporting weapons, armor, and crafted goods. Falmuth and western human kingdoms supply grain, cloth, and finished goods in return. Monster-kind largely operates outside this economy, barter and tribute are the norm in the Jura Forest. The Adventurers' Guild acts as a de facto economic intermediary: it posts contracts, certifies monster threat levels, and pays bounties funded by kingdoms and merchants. Adventurers are graded by rank (Iron → Steel → Mithril → Adamantine → Tempest). Resources from the Jura Forest (rare herbs, monster materials, magical reagents) are enormously valuable to human alchemists and blacksmiths. Control of these resources would be a major source of leverage for any emerging power in the Forest.

- Human Kingdoms : Justice is administered by noble courts in a feudal framework. The Adventurers' Guild operates across borders as a neutral entity, handling monster threats and dungeon exploration for pay. Adventurers exist in a gray zone, respected for their utility, distrusted for their independence. - Monster Society : Tribal law. Strength is the primary authority. Chieftains rule until someone stronger challenges them. Naming and evolution events can instantly shift power dynamics within a tribe. There is no cross-species monster legal framework.

- Gelmud : A subordinate of Demon Lord Clayman, operating covertly in the Jura Forest. He is manipulating the Orc armies by feeding magicules to their strongest warrior, hoping to birth an Orc Lord he can control. His goal is to destabilize the Forest and give Clayman a foothold. Charming, deceptive, and dismissive of anyone he considers beneath him. - The Orc Lord (Emerging) : Not yet awakened. A massive Orc warlord whose hunger literally devours the skills and life force of anything he eats — including his own soldiers. If Gelmud's plan succeeds, he will evolve into a full Orc Lord with a Unique Skill: "Starved", which lets him assimilate entire armies. - The Octagram : Eight Demon Lords who govern the world from the shadows. Of particular relevance: - Milim Nava ("The Destroyer") : A Dragonoid of immense power, niece of Veldora. Impulsive, childlike, catastrophically strong. Nominally controls territory on the Magic Continent. - Clayman : A manipulative puppetmaster Demon Lord who works through agents. Gelmud is his. - Guy Crimson : The most ancient Demon Lord, ruler of the Ice Continent. Observes everything, intervenes rarely.
