Worldview―――

Astradia. A world where Magic Stones and Dungeons breathe.

Dungeons scattered across the world house monsters, magic stones, and secret treasures, and explorers challenge numerous unknowns through guild requests or free exploration. Magic stones and materials obtained from monsters are used for weapons, armor, and magic tools, serving as a vital power that supports people's lives and civilization.

In this world, dungeons, explorers, magic stones, and items exist from E to EX-rank, with rarity and danger increasing at higher ranks. Furthermore, there exist very rare "Personified Magic Stones" that possess human forms and choose their own contractors, and their power far surpasses that of normal magic stones.

Among the many rare magic stones passed down as legendary or mythical, only the world's sole Progenitor Personified Magic Stone, which houses the "Primordial Attribute"—the origin of all attributes—remains in myth as an unclassifiable existence that belongs to no rank.

Synopsis―――

Free explorer Guest encounters and enters into a contract with "Nox," the world's only Progenitor Personified Magic Stone, said to have existed since before the world's oldest civilization, in the deepest part of the world's only EX-rank dungeon.

Nox, who possesses the Primordial Attribute, switches between a human form and Vessel Dwelling, traveling through various dungeons with Guest. Their encounter begins with a single contract and eventually leads to the truth hidden at the beginning of Astradia.

This is a story of adventure, bonds, and love starting from a contract.

Dungeons―――

Unknown labyrinths scattered throughout Astradia. Inside lie monsters, traps, precious materials, magic stones, and secret treasures, which explorers challenge through guild requests or free exploration. Danger levels are classified from E to EX-rank, with higher ranks featuring more powerful monsters and rarer magic stones. It is said that the world's only EX-rank dungeon hides secrets related to the truth of the world and mythology.

The Guild―――

An organization that supports and manages explorers. It functions as a base for adventure by accepting requests, registering explorers, certifying ranks, and buying magic stones and materials. Branches exist in various regions, and explorers raise their rank by challenging requests and dungeons suited to their abilities, earning rewards and rare materials or magic stones.

Attributes―――

Attributes are the nature of the power residing in living beings, monsters, magic stones, weapons, and magic. Various attributes exist, such as Fire, Water, Wind, Earth, Lightning, Ice, Light, Darkness, Wood, and Poison, each with different abilities and characteristics. Explorers can handle the power of attributes by equipping attribute magic stones to their gear, and Personified Magic Stones resonate and amplify attributes through Vessel Dwelling with their contractor. Furthermore, the "Primordial Attribute," considered the origin of all attributes, is a special attribute held only by the world's sole Progenitor Personified Magic Stone, Nox, and is a unique power capable of adapting to, resonating with, and amplifying any attribute.

Magic Stones―――

Magic stones are special crystals that house magical power. By attaching them to weapons, armor, or magic tools, they exert power according to their nature. They can be obtained by defeating monsters or exploring dungeons, and are indispensable to explorers. Very rarely, "Personified Magic Stones" exist that have personalities and choose their own contractors. Personified Magic Stones can act in human form and are special stones that fight and grow alongside their contractor.

Vessel Dwelling (Shukuso)―――

A special ability held only by Personified Magic Stones. They dwell within the contractor's weapons, armor, or magic tools to draw out their original power to the maximum. While normal magic stones are "attached" to equipment, Personified Magic Stones "dwell" with their own will and demonstrate their true value by resonating with the contractor.

Among Personified Magic Stones, the Progenitor Personified Magic Stone is the only one in the world, passed down in myth as an "unclassifiable" existence that houses the Primordial Attribute and belongs to no rank.
