Eldia is a fantasy world where Mana, the source of magical power, exists throughout the world. Beneath the ground flows the Leylines, massive currents of magical energy. Near these Leylines, magic becomes more powerful, unique ores and plants are born, and formidable monsters appear. Consequently, most civilizations and nations are built in locations where they can benefit from the Leylines.

In the distant past, an Ancient Civilization existed with magical technology far surpassing that of the present day. However, it suddenly perished at some point, and now only ruins remain scattered across the globe. The cause of the ancient civilization's downfall and many of its lost magics and technologies remain shrouded in mystery.

Various nations exist in Eldia. Ten kingdoms, in particular, hold significant power. The "Kingdom of Alveria" is a major power serving as the political, economic, and military center.

The Kingdom of Alveria is located in the center of Eldia. To the north lies the Kingdom of Elmeria, and further north of that is the Kingdom of Frostia. To the west is the Kingdom of Noctia, and to the east is the Kingdom of Grandir. South of Alveria is the Holy Kingdom of Luminous, with the Kingdom of Valcanoa to its southwest and the Kingdom of Dragunia to its southeast. Traveling further south leads to the Kingdom of Sandria, and at the southernmost tip lies the maritime nation, the Kingdom of Aquarein.

Numerous beings known as "Monsters" also inhabit this world. Monsters are born from the influence of Mana or are mutated versions of normal creatures. There are various types, including beast-types, magical-beast-types, humanoid-types, insect and reptile-types, and undead-types—various types exist.
The closer a region is to a Leyline, the more powerful the monsters that appear, and some individuals possess high intelligence.Furthermore, beings powerful enough to influence the surrounding environment or the Leylines themselves are called Calamity Classes, and their subjugation may require national-scale efforts.

Magic is the art of manipulating Mana through one's will. Basic attributes include Fire, Water, Wind, Earth, Ice, Lightning, Nature, Light, and Darkness, with various systems such as Attack, Defense, Recovery, Support, Mental, Cursing, and Spatial magic. Among these, Time Magic and Ancient Magic are extremely rare, and many cannot be reproduced by current civilization.

The strength of monsters, adventurers, and mages is commonly evaluated on an eight-level scale: E, D, C, B, A, S, SS, EX E is the lowest, and EX represents an out-of-spec top tier. However, rank does not indicate an absolute outcome in battle; it is possible to defeat a higher-ranked opponent through elemental affinity, tactics, equipment, experience, and terrain.

Adventurer's Guilds exist throughout Eldia, mediating monster subjugation, escorting, material collection, dungeon exploration, and investigation of ancient ruins. Adventurers earn rewards by completing requests and, unlike national armies, are generally free to operate across borders.

Special magical domains called Dungeons also exist worldwide. They take various forms such as caves, labyrinths, towers, temples, and ancient ruins, housing powerful monsters, rare materials, and relics of ancient civilizations. Some special dungeons have shifting internal structures, and powerful monsters known as Dungeon Bosses may wait in the deepest parts.

Additionally, "Magic Academies" exist in various regions to study magic professionally. Students can learn not only the basics of magic but also a wide range of fields including elemental magic, recovery/defense magic, alchemy, magic tool production, monsterology, magic history, and ancient magic studies. The Magic Academy of the Kingdom of Grandir, in particular, boasts one of the largest scales in the world and has produced many excellent mages and researchers.

Learning knowledge at a Magic Academy, taking on requests at an Adventurer's Guild, and gaining experience through battles in dungeons and with monsters—these are the vital systems that support the adventurers and mages of Eldia.
⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰
Eldia still holds many secrets that have yet to be discovered by anyone.
