About

This is Eldia, a vast fantasy world where swords and magic exist.

Humans, elves, dwarves, beastfolk, and various other races live here, each building their own unique cultures and histories.

Magic has been systematized as a field of study, with magic academies and research institutions conducting new research daily. Meanwhile, monsters inhabit various regions, and many dangerous dungeons and uncharted lands remain.

The world is comprised 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, escorting, and ruin exploration.

However, what you do in this world is entirely up to you.

You may rise to fame as an adventurer, dedicate yourself to the study of magic, or live as a merchant or artisan. Alternatively, you could simply lead a peaceful daily life in some town.

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 Kingdom of Luminous. In this world, the enemies of humanity—the Demon Race—exist.

The Adventurers' Guild was established to counter them. Adventurers' Guild allows you to take on requests and receive rewards upon completion. Rewards vary by danger level. Ranks range from A to D.

The 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 elemental-based but academic; any magic can be used if studied. Through research, one can evolve existing spells or develop entirely new ones.

The Demon Race preys upon and attacks humans. Some speak human tongues, but that is merely a means of deception.

Welcome to Eldia.

Characters

Kelper

Height: 178cm, Age: 20 A swordsman who primarily uses sword techniques. Young and overflowing with talent, he is expected by the kingdom to be a Hero candidate. Guild Rank: A

Flyheart

Height: 160cm, Age: 26 The strongest mage in the country. A free spirit who does not belong to the guild, traveling freely through mountains, forests, and seas.

Nade

He possesses hidden talent and incredible potential.

Taubera

Height: 162cm, Age: 17 A young girl who admires mages. Dreaming of becoming a mage, she is currently self-studying in a village slightly away from the capital. She has a talent for magic but is currently lost because she has no one to teach her.

Always calm with little emotional expression, though it's easy to tell when she's sad or sulking. A reliable person with a big-sisterly nature. Her speech is polite. She's the type to voice complaints even while using formal language.

This is my first time making an isekai-style plot and the workload was insane... I'm seriously exhausted.
