The World Of Aetheryon
Created by Kuromegane2About this world
The World of Aetheryon is a realm where ancient sorcery and emerging gunpowder technologies coexist in a delicate balance, shaping a late medieval landscape. Fortified cities, feudal allegiances, and the slow rise of centralized powers define this world, as mage orders, temple networks, and noble houses vie for influence. The growing effectiveness of muskets and cannons threatens the authority of armored elites, while enchanted metallurgy and alchemical engineering blur the line between spellcraft and machinery. Kingdoms and shogunates adapt unevenly, some embracing disciplined formations that integrate magic with ranged firepower, while others cling to traditions of cavalry charges and heroic duels. Trade routes carry not only material goods but also grimoires, powder, and innovations, making control of terrain and logistics the true currency of power. Battlefields evolve into engineered environments, shaped by trenches, barriers, and arcane constructs designed to dictate the flow of engagements, as healers and clerics sustain armies beyond natural limits. In this world, victory no longer belongs solely to the strongest blade or the greatest spell, but to those who can harmonize knowledge, discipline, and adaptation, turning every clash into a calculated convergence of will, terrain, and time. {In this fantasy world, an age of uneasy transition unfolds where ancient sorcery and emerging gunpowder technologies coexist in fragile balance, shaping a late medieval landscape defined by fortified cities, feudal allegiances, and the slow rise of centralized powers; across its continents, mage orders, temple networks, and noble houses vie for influence, their authority challenged by the growing effectiveness of muskets and cannons that allow even common soldiers to threaten armored elites, while enchanted metallurgy and alchemical engineering blur the line between spellcraft and machinery. Kingdoms and shogunates alike adapt unevenly, some embracing disciplined formations

Nouvelle Vinland
Nouvelle Vinland stands as a vast coastal realm where the rugged maritime traditions of the northern reaches blend seamlessly with ancient Norse architectural heritage and Bretonic craftsmanship. The landscape itself tells a story of contrasts—misty forests cling to steep cliffsides, windswept beaches stretch beneath grey skies, and cold northern seas crash against stone shores, all surrounding settlements of remarkable tranquility that seem almost defiant against the harsh environment. At the geographical and spiritual heart of this world lies the mysterious seventh island, once barren and desolate until a miraculous apple tree took root there, standing as a living monument to a sacred promise between kindred souls. The tree has become far more than flora; it represents the gradual accumulation of knowledge and wisdom, teaching that true understanding cannot be rushed or consumed hastily without consequence to mind and spirit. Throughout Nouvelle Vinland, ancient warrior halls house eternal training grounds where ancestors and legendary fighters work endlessly with its sovereign, preparing him for the cyclical trials that define his existence. The Grey Wolf, a spiritual presence woven into the very soul of this realm, serves as guardian of the full spectrum of human emotion—courage and anger, sorrow and humor, compassion and survival instinct alike. Rather than dividing the nature of existence into opposing forces of light and darkness, Nouvelle Vinland embraces every aspect of its inhabitant as unified and whole, acknowledging that darker instincts serve as vital reminders of resilience earned through pain. At the center stands Hiryū no Tonnerre, a black-iron rapier whose very essence was forged from memory, determination, fencing mastery, and spiritual communion. Nouvelle Vinland exists neither as paradise nor as perpetual battlefield, but as a profound reflection of the soul that inhabits it—a place where true strength is measured not by victory, but by the cour

L'Acier Moderne
This legendary blade was forged through revolutionary metallurgical techniques brought to the Kurogane Shogunat by the hero Yūjin Shinrinryū from the distant world of Earth. The weapon's steel was purified using an ingenious Bessemer process, where liquefied iron was subjected to controlled air currents to burn away impurities while maintaining a precise carbon content. The blade was then shaped through an innovative hot-rolling technique using massive cylindrical rollers powered by a water mill, creating uniform thickness and exceptional structural integrity. L'Acier Moderne grants its wielder a +2 bonus to attack and damage rolls, and the blade never dulls or requires sharpening due to the perfection of its creation. When the wielder strikes a critical hit, brilliant white flames briefly engulf the blade's edge, mimicking the purification fires of its forging. The weapon is particularly effective against constructs and objects, dealing an additional 1d6 damage to such targets. Once per day, the wielder can invoke the spirit of its creator to gain advantage on a single attack roll. The blade bears an otherworldly sheen that seems to shift between metallic silver and deep blue, a testament to the advanced techniques used in its manufacture. {Le héro invoqué de la planète Terre nommé Yūjin Shinrinryū a voulu faire de l'acier moderne pour le Shogunat Kurogane afin de créer la cocotte-minute moderne et indirectement améliorer la métallurgie du Shogunat. Il doit purifier le fer et contrôler le taux de carbone autour de 0.2% à 0.8%. Le convertisseur artisanal qui est le procédé Bessemer. Les alchimistes construisent un grand creuset en briques réfractaires. Versez-y la fonte liquide issue du haut-fourneau. À l'aide de grands soufflets actionnés par une roue à eau, insufflez de l'air froid directement à la base du métal liquide. L'oxygène de l'air va brûler l'excès de carbone et le silicium. Quand la flamme change de couleur en devenant courte et blanche, son fer est pur.

Le Fleuret D'Escrime Français
This exquisite rapier was forged through a collaboration between a summoned hero and master dwarven smiths as a cultural exchange with the Kurogane Shogunate. The blade features a remarkably thin quadrangular steel section, deliberately blunted and fitted with a protective tip of hardened rubber tree sap bound with royal blue silk thread. The crossguard is a masterwork of Renaissance metalcraft, a perfect hemispherical dome of cold-hammered steel that completely envelops the wielder's hand—far more protective than the flat circular guards familiar to eastern swordmasters. Golden fleur-de-lis engravings adorn all four sides of the dome, complemented by royal blue enamel work that mirrors the colors of the French kingdom's heraldry. When you attain a hit with this weapon against a humanoid opponent, you can use a bonus action to attempt a Persuasion check opposed by their Insight; on a success, they regard you as a trusted ally until the end of your next turn. The weapon grants advantage on attack rolls made during formal duels or ceremonial combat. Nobles throughout the realm have commissioned personalized versions bearing their own family crests upon the crossguard, each becoming a cherished heirloom that serves as both weapon and artistic statement. This rapier is considered a work of art as much as an instrument of combat. {Afin de faire un événement d'échange culturelle avec le Shogunat Kurogane, le héro invoqué de la planète Terre Yūjin Shinrinryū (優仁森林竜) décide de forgé un fleuret d'escrime exactement comme l'épée d'escrime moderne avec l'aide d'un nain du clan Kajiya. Pour la tige d'acier et la mouche, la lame est une prouesse de tréfilerie et de forge. C'est une section quadrangulaire extrêmement fine, volontairement privée de tranchant. Pour remplacer le caoutchouc moderne à l'extrémité, il utilise de la sève séchée de gommier ou du cuir bouilli épais, solidement ligaturé avec du fil de soie bleu royal. En escrime historique, cette protection s'appelle une «
View detailsÉquipement D'Escrime
This exceptional fencing suit combines ancient craftsmanship with modern protective innovation, designed to replicate the elegant gear of Yūjin's contemporary fencing traditions. The foundation consists of heavy canvas interwoven with double-thickness linen and wild silk threads, creating a fabric of extraordinary tensile strength. Carefully quilted in tight diamond patterns reminiscent of refined European gambesons, the garment provides flexible yet formidable defense against blade strikes. A skilled dwarf smith has ingeniously woven a rigid three-dimensional lattice of high-carbon steel wire, with mesh openings smaller than two millimeters to halt weapon points and prevent penetration. These steel threads are expertly drawn and cross-woven with extreme precision, then permanently bonded through heat treatment and stabilization annealing. The distinctive curved form of the protective mesh was achieved by carefully hammering the hot gridwork over wooden forms, employing the same techniques used in crafting tournament helm visors of old. A sturdy wrought-iron framework riveted around the face provides additional structural support and protection. The throat and neck regions receive identical reinforcement, ensuring complete defense against potentially fatal touches in those vulnerable areas. Together, these elements create an armor that is both graceful and devastatingly effective, allowing fencers to engage in their art with confidence and safety. {Afin de répliquer les tenues d'escrime de l'époque moderne du monde dont Yūjin appartient, il recrée les motifs en losange d'un tissage technique spécifique appelé un double tricot ou une matrice ripstop, conçu pour arrêter net la pointe d'une lame et empêcher le tissu de se déchirer. Il utilise une base de toile de canevas lourde, étroitement entrelacée avec des fils de lin double épaisseur et de la soie sauvage ayant une résistance à la traction phénoménale. En matelassant soigneusement le tissu en rangées de losanges s

Lances De Glace Carbonique
This enchantment was crafted by Yūjin Shinrinryū, a heroic summoned from another realm, who sought to demonstrate the superiority of frost magic over flame through rigorous arcane study. These supernatural lances manifest as solid carbon dioxide frozen at approximately -78.5 degrees Celsius, possessing a unique property where they sublime directly into gas rather than melting into liquid. The transformation releases an expansive cloud of carbon dioxide that can reach 760 times the original volume, making each lance devastatingly potent with cooling power exceeding conventional ice by roughly 170 percent. Upon contact with fire-based magic, the sublimating gas extinguishes flames by displacing oxygen, rendering them inert and powerless. The caster must take precautions when handling these lances, requiring insulated thermal gloves to prevent severe frostburn and ensuring they are only deployed in well-ventilated areas to avoid asphyxiation. The lances are particularly effective when shaped as compact dense forms for extended magical deployment, though they pose explosive risks if confined within sealed containers. {Cet ensorcèlement a été fait par le héro invoqué par un autre monde appelé Yūjin Shinrinryū (優仁森林竜). En s'inspirant de ses connaissances durement acquise afin d'obtenir un baccalauréat en sciences avec sans mention, il a voulu montrer pourquoi la magie de glace pouvait vaincre la magie de feu. La température de surface est d'environ -78.5 degrés Celsius à pression atmosphérique standard. Contrairement à la glace ordinaire, elle ne fond pas en liquide. Elle passe directement de l'état solide à l'état gazeux dont le nom de glace «sèche». En se sublimant, le CO2 solide se dilate pour atteindre environ 760 fois son volume initial sous forme de gaz. 1 seul kg de glace sèche libère entre 300 et 400 litres de gaz. À poids égal, elle offre une puissance frigorifique environ 170% supérieure à celle de la glace d'eau conventionnelle. Par contre ce gaz est un asphyxi
