Isekai World • New Life in Another World

Jiangshi A very rare species of Therros whose body retains the appearance of a deceased person, but whose soul has been restored through spiritual magic. Jiangshi bear a Spirit Seal affixed to their foreheads, a runic scroll that stabilizes the flow of mana in their bodies and prevents them from losing control of their instincts. If the seal is removed or destroyed, the Jiangshi temporarily enters a feral state until they regain their balance.

Contrary to legend, the Jiangshi of Therros are not evil. They coexist with other species and are renowned for their incredible resilience, longevity, and regenerative abilities. They barely need sleep, are immune to most diseases, and possess an exceptional affinity for spirit magic, seals, and barriers. Due to their nature, many work as temple guardians, exorcists, relic custodians, or guardians of sacred sites.

Their appearance is practically human, with slightly pale skin, bright eyes when they use magic, and the characteristic seal on their forehead, which many decorate with personal symbols without losing its magical function.

Vampires A long-lived species with an elegant appearance and refined features. Their skin is typically pale, and they possess retractable fangs. They draw their life force from blood, although alchemical substitutes now exist that allow them to coexist peacefully with other races. They are renowned for their speed, regeneration, heightened senses, and affinity for blood magic, shadow magic, and hypnosis. Many vampire families are part of the nobility of Therros. Angels Beings born of celestial energy, they inhabit floating cities and temples suspended above the clouds. They possess feathered wings that they can conceal with magic, allowing them to coexist with other species undetected. They are experts in holy magic, barriers, and healing, and also act as mediators in international conflicts. Though generally peaceful, they are fearsome warriors when they must protect the innocent. Giants A humanoid race whose height ranges from three to six meters. Their immense physical strength and endurance make them excellent builders and defenders of fortresses. Unlike in ancient myths, modern giants are civilized and maintain diplomatic relations with other countries. Many work building cities, bridges, and walls impossible for other species. Nekomatas Distant relatives of kitsune, they possess feline ears and two tails from birth. They are agile, silent, and skilled in shadow magic and minor illusions. They excel as explorers, spies, messengers, or adventurers. Their natural curiosity often leads them to travel the world in search of knowledge and relics.

Sirens Inhabitants of seas, lakes, and large rivers. They possess a humanoid form and can alternate between legs and a tail depending on the amount of water surrounding them. They are skilled in water magic, healing, and controlling currents. Their cities lie beneath the ocean, protected by enormous magical barriers that keep out the most dangerous sea creatures. Incarnate Spirits Beings born from the concentration of pure mana that acquired a physical body. Their appearance is usually completely human, although they always possess a distinctive feature related to the element they represent, such as crystal eyes, fiery hair, or luminous markings. They do not age conventionally and are extremely rare, as their birth depends on exceptional magical phenomena. Werewolves A branch of the Beastmen specializing in transformation. They normally maintain a human appearance with some animal features, but can assume a much more powerful hybrid form during combat. Their strength, speed, and regenerative abilities increase considerably, though mastering this transformation requires years of training. The wolf, tiger, and bear clans are the most well-known in Therros.

Humanized Onis

Descendants of the ancient oni who abandoned warfare to live among other races. They retain one or two horns, extraordinary physical strength, and great resistance to hostile mana. Although their appearance can be intimidating, most lead ordinary lives as soldiers, guardians, mercenaries, or artisans. They are highly valued for their honor and for always keeping their word.

Humanized Demons

The demons of Therros are not inherently evil creatures. They possess an almost human appearance, distinguished by their horns, tails, glowing eyes, or small wings depending on their lineage. They are notable for their enormous mana reserves and their affinity for dark magic, fire, and curses, though they can also master any other magical branch. Following ancient peace treaties, most coexist with other species and occupy positions such as mages, researchers, merchants, or nobles.

Draconians

Known as humanoid dragons, they possess a human-like appearance with partial scales, horns, reptilian pupils, and, in some cases, a tail or wings. They inherit a small portion of the power of the ancient dragons, granting them a long lifespan, physical resilience, and a natural affinity with a specific element, such as fire, ice, lightning, or wind. They are considered one of the most powerful species on Therros and often act as guardians of mountains, volcanoes, or ancient ruins.

Kitsunes

A spiritual species with fox-like features, recognizable by their ears and one or more tails that increase in length as they grow in power and experience.

Many live among humans, concealing their abilities, while others protect sacred forests and sanctuaries.

Dwarves

Expert blacksmiths, architects, and miners, dwarves are renowned for their short stature, sturdy build, and extraordinary physical stamina. Their cities are often found in mountains or underground, where they forge some of the finest weapons and armor in Therros using enchanted ores. Though proud and strong-willed, they maintain trade relations with nearly every nation and are famous for their discipline and loyalty.

Dornelfos

A subspecies born centuries ago from the union of dwarves and halelfs. They retain the short stature and strength of dwarves, but possess slightly pointed ears and a greater magical affinity than their dwarven ancestors. They are masters of runeforging, a discipline that combines smithing with enchantments to create weapons, armor, and tools capable of storing or channeling mana. Thanks to their balance of physical strength and magical intelligence, many become elite artisans, arcane engineers, or guardians of national treasures.

Halelfos

Descendants of a mixture of humans and elves. They are shorter than a common elf and possess slightly pointed ears, much smaller than those of their relatives. They inherit a moderate affinity for mana and a lifespan longer than that of humans, though shorter than that of elves. Thanks to their ability to adapt to different cultures, they often work as merchants, adventurers, diplomats, or researchers.

Ice

Considered the oldest and purest branch of the elves, they are noticeably taller, elegantly built, and possess long ears that symbolize their profound sensitivity to mana. Their mastery of magic surpasses that of any other elven subspecies, allowing them to manipulate vast amounts of energy with exceptional precision. Most hold positions such as archmages, guardians of relics, or leaders of sacred groves, though some leave their homelands to roam Therros in search of knowledge.

Humanized Goblins

Far from the ancient legends, the goblins of Therros evolved into an intelligent and civilized species. They retain their short stature, pointed ears, and skin of varying shades of green or gray, but their appearance is much closer to that of humans. They are known for their ingenuity, creativity, and skill in crafting tools, machinery, and magical artifacts. Many work as artisans, arcane engineers, merchants, or alchemists, and are highly respected for their ability to solve problems with limited resources.

Humans

The most numerous and adaptable species on Therros. They do not possess an outstanding magical affinity by nature, but their capacity to learn, innovate, and master various disciplines has allowed them to found some of the most influential kingdoms. They are the species that most often receives heroes summoned from other worlds.

Beastly

Known as half-human, half-animal beings, the Beastly possess physical traits such as ears, tails, horns, claws, or fangs, depending on their lineage. They maintain a mostly human appearance, and each clan develops abilities related to their species of origin, such as heightened senses, speed, or great strength. They live both in their own territories and integrated into human cities, where they are renowned as excellent explorers, hunters, and warriors.

Elves

A long-lived race with a strong connection to mana and nature. They often live for centuries and are renowned for their innate talent for magic, archery, and alchemy. Their cities are hidden among ancient forests or built around giant trees imbued with magical energy. Although they value tradition, many modern elves collaborate with other species and participate in the politics of Therros.

The World Registry of Heroism: The Guild System In this world, peace and progress depend not only on royal armies, but also on an interconnected global network known as the Adventurers' Guild System. This independent institution serves as the heart of hero recognition, a meritocratic mechanism where fame, political power, and wealth are not inherited, but rather etched in blood, sweat, and deeds on the central register. Anyone with sufficient courage can present themselves at a Guild and receive their Crypto-Magic Identity Badge, an artifact linked to the wearer's soul that automatically records their achievements and assesses their level of contribution to the world. The Paths of Recognition: The Four Columns To climb the ranks in the hero system and gain worldwide fame, Guild members can specialize or excel in four fundamental pillars: Monster Subjugation: This is the most direct path to renown. From clearing goblin infestations from local farms to hunting mythological beasts that ravage entire regions, each monster defeated grants "Calamity Points," which determine the hero's brute strength and martial valor. Pacifying (Bandit and Outlaw Hunt): Not all dangers are monsters. The Guild issues reward posters for the capture or elimination of criminals, gang members, and deserters. Search and Rescue Missions: Intended for those whose heroism lies in protection. This includes escorting convoys through hostile territories, evacuating villages during natural disasters, or rescuing hostages. Mapping and Dungeon Exploration: The first to venture into ancient ruins, forgotten temples, or dungeon rifts, basically mapping unknown terrain.

The Prestige Rank: From Iron to Adamantium A hero's social recognition and privileges are strictly determined by their badge rank, which is divided into metals: Low Ranks (Iron, Bronze): Novices who perform local tasks. Their fame doesn't extend beyond the neighborhood taverns. Mid-Rank (Silver, Gold): Established heroes. Their names resonate in the capital cities; they lead guilds. Supreme Rank (Adamantium): Living legends. Only a few dozen exist worldwide. An Adamantine-rank hero; their mere presence in a region can deter armies or quell rebellions, and their deeds are sung in history books while they are still alive.

Aetheris, the City of the First Awakening

The first city most people summoned from other worlds encounter. Built upon a massive floating island, Aetheris is the center where newcomers learn the language, history, and workings of Therros's magic. Its streets blend white stone architecture with arcane technology, and its academies train both native inhabitants and travelers from other worlds. It is renowned for its enormous Horizon Tower, from which portals extend to the rest of the continent.

Valdrek, the Capital of the United Nations

Located on the central continent, Valdrek is the largest city in Therros and its political heart. Embassies from dozens of countries coexist with guilds of adventurers, merchants, and mages. Its immense enchanted wall protects districts dedicated to alchemy, magical smithing, and relic research. Many expeditions depart from here toward the ruins of the Great Fracture, making it a key location for adventurers and explorers.

Noctis Caelum, the City Above the Clouds

The most advanced floating city on Therros, suspended by colossal astral crystals, is a place reserved for the greatest sages, arcane engineers, and guardians of knowledge. Its bridges of light connect entire districts, and its libraries safeguard the records of heroes summoned throughout history. From Noctis Caelum, magical anomalies appearing in the world are monitored, and the portals connecting Therros to other dimensions are studied.

Therros is a world born from the Astral Core, a source of magical energy that emerged before time and shaped the continents, oceans, and skies. From its currents arose the first sentient beings, who learned to channel magic through nature, the stars, and the world's own spirits. For millennia they prospered until ambition unleashed the Great Fracture, a war so devastating it shattered mountains, lifted lands into the sky, and opened chasms where reality became unstable.

After centuries of rebuilding, ancient civilizations unified some of their knowledge to prevent another catastrophe. Magic ceased to be merely a weapon and became a driving force for progress. Floating cities were built, supported by enormous arcane crystals; bridges were suspended between celestial islands; and networks of portals connected regions separated by thousands of kilometers. The seas conceal submerged kingdoms protected by magical barriers, while vast living forests and crystal deserts preserve relics from the ancient era.

Today, Therros is divided into numerous countries and empires, each with its own distinct culture and traditions. Some wield elemental magic, others arcane technology, or a connection to ancient creatures. While trade and alliances maintain a fragile balance, political tensions, border conflicts, and the exploration of the Great Fracture's ruins threaten to awaken long-forgotten forces. Above the clouds, beneath the oceans, and in the corners where reality still lingers, Therros remains a world of wonder, mystery, and peril, capable of altering the fate of all nations.

In this world, magic is very volatile. It works through magic circles with different types of hieroglyphs to create a specific spell. With these, one can create traps, heals, summons, attacks, etc. Magic can be used by any being within the world; each existing being has a different initial level of magic, although it can be trained to improve. Spells can be manifested through wands, hands, or large magic circles on the ground. Magic wielders are divided into levels according to their mastery of it; if you use a wand you can be considered a novice, while manifesting it without the use of anything shows that you are someone experienced. Magic can be studied in different schools or through observation. In schools, different types can be taught, since normal magic focuses on elements such as earth, water, air, and fire, or some involve black magic. Magic is not only about the elements; you can combine or use different types of magic such as lightning or darkness, although these are more difficult to master and/or control. Healing magic is something everyone should know about.
