There is no set story. Only infinite freedom.
About
This is the vast otherworld of Eldia, where swords and magic exist.
Humans, elves, dwarves, beastfolk, and various other races live here, each building their own cultures and histories.
Magic of This World
Magic is systematized as an academic discipline, with new spells being researched daily at magic academies and research institutions. Meanwhile, monsters inhabit various regions, and many dangerous dungeons and uncharted lands still remain.
World Affairs
The world consists of multiple kingdoms and nations, each with its own distinct politics, culture, economy, and military power. Furthermore, there exists a Demon King who poses a massive threat to humanity.
The Adventurers' Guild handles various requests, such as monster subjugation, escort missions, and ruin exploration.
However, what you do in this world is entirely up to you.
Whether you wish to make a name for yourself as an adventurer, research magic, live as a merchant or artisan, or simply lead a peaceful daily life in some town, the choice is yours.
There is no fixed protagonist, and no predetermined story.
Your life in Eldia begins with your own choices.
The starting point is Luminaria, the royal capital of the Luminous Kingdom. In this world, the Demon Race exists as the enemy of humanity.
The Adventurers' Guild was established to counter them. You can accept requests at the guild and receive rewards upon completion. Rewards vary based on the danger level. Ranks exist, ranging from A to D.
Common Currency: "Rune"
One stone coin is 1 Rune. One iron coin is 10 Runes. One copper coin is 100 Runes. One silver coin is 1,000 Runes. One gold coin is 10,000 Runes.
Magic in this world is not attribute-based but academic; any magic can be used if studied. Through research, existing spells can be evolved or entirely new magic can be developed.
The Demon Race attacks and devours humans. Some speak human tongues, but that is merely a means of deception.
Welcome to Eldia.
Examples of How to Play — Just a few ideas
There is no set story in Eldia. Below are samples of how to start, but feel free to change your profession, race, and goals as you wish.
1. Classic Adventurer Play
Arrive at the royal capital Luminaria as a novice adventurer and start by registering at the guild. Example opening: "I'm a swordsman who just arrived in the capital. I'd like to register at the Adventurers' Guild."
2. Growing with a Rookie
Form a party with the fellow rookie Nade and gradually raise your rank by taking on simple requests. A growth-oriented style where you get stronger alongside a fearful partner.
3. Magic Research Play
Start as a student at the magic academy or a self-taught mage. Your goal is to improve existing spells or develop your own unique magic. Example: "I'm self-studying magic. I want to create a new type of utility spell."
4. Slow Life / Eatery Play
Live in the capital without fighting. Work at the eatery where the poster girl Altag is, become a regular, or come up with new signature menu items.
5. Merchant / Artisan Play
Earn a living as a blacksmith, apothecary, chef, or peddler. A management-oriented style where you source materials from across the continent to sell in the capital, create magic items, or own your own shop.
6. Traveling the Continent
Become a traveler journeying across the continent of Ubera. Wander without a set destination, meeting Treffer the elf in the western forest or visiting various towns and dungeons.
7. Capital Daily Life / Social Play
Live as an ordinary resident of the capital and gradually become close to the townspeople, such as Segen from the church or Ele, the daughter of a famous family. A style where you nurture relationships, including romance, as you play.
8. Veteran / Strongest Play
Set yourself as an A-rank adventurer or a skilled magic swordsman from the start, taking on high-difficulty requests with Kelper or Zan. A powerful protagonist style capable of going toe-to-toe with the Demon King's generals.
9. Demon King's Army Play
Start from the perspective of the demons or the Demon King's army rather than the humans. Experience Eldia from the enemy side, perhaps being involved in territorial expansion under Demon King Herscher.
