・About the World

A diverse mix of humanoid races exists, including Humans, Elves, Beastmen, Dwarves, Hobbits, and Demons. There are six major nations, each with its own capital and a Great Dungeon (Labyrinth).

Small and medium dungeons are scattered throughout the lands, managed by state-run guilds according to their territory. Various ecosystems have formed in different regions, consisting of magical creatures with mana and other creatures without it.

・Dungeon Details

The origin and purpose of each dungeon vary. The interior and surrounding areas possess unique ecosystems, mostly inhabited by magical creatures, including many endemic species. Dungeons are divided into distinct Strata, which are further divided into 3 to 10 Floors. (e.g., Stratum 1, Floor 1) Great Dungeons typically have around 7 Strata, while small to medium ones have 5 or fewer, though unknown Strata are occasionally discovered during detailed exploration. Generally, Strata 1-2 are Shallow Layers, 3-5 are Middle Layers, and 6+ are Deep Layers; danger and resource value increase as one descends. Dungeons support the economies of nations and cities as a unique industry.

Exploration requires an adventurer license from a national guild, with ranks S/A/B/C/D determined by skill and track record. Ranks D through A are primarily based on ability and achievements, Rank A is the standard top tier, with only a few dozen per country. Rank S requires achievements beyond Rank A, such as traversing unexplored territory, special subjugations, large-scale rescues, or discovering numerous new species, followed by a rigorous review. Those holding S-rank licenses in multiple countries are a mere handful worldwide. Adventurers typically form parties, and the party rank is synchronized with the leader's rank.

・About Dragons

Powerful magical creatures that live in small numbers across the world. They possess intelligence close to humans, and some can understand human speech. Only designated species possessing an ultra-high concentration of unique mana called "Dragon Aura" are called Dragons; others are named Drake, Wyvern, Wyrm, Hydra, etc. They have extraordinary lifespans, and it is said they never truly perish even if slain by human hands. Because they exert significant influence over nature and ecosystems, subjugation requires national permission, and capture is strictly prohibited worldwide.
