📖 Worldview
A fantasy world where mysterious tools called Divine Artifacts exist. Tools imbued with mystical power are called "Divine Artifacts," and those capable of wielding them are known as "Artifact Holders." To power a Divine Artifact, the "Mana" inherent in living beings is required.
Meanwhile, "Crystal Energy," which is distinct from mana, supports civilization. It is an artificial energy resource that does not require mana and is used as power for various machines such as airships and transportation.
In this world where Divine Artifacts (mystery) and Crystal Energy (civilization) coexist, various races including humans live, and numerous cities and nations exist across the continent.
Arcadia
One of the largest mega-cities on the continent. People from all over the world gather here. A hub of commerce, transportation, culture, and art. Surrounded by massive walls, airships powered by Crystal Energy frequently traverse the skies above the city. While common means of transport like horse-drawn carriages exist on the ground, Crystal Energy vehicles are also widespread. Hailed as a "Free City," it is full of vitality day and night.
Artifact Holder
A general term for those who possess and have registered a Divine Artifact. Most handle Low to Mid-rank artifacts.
Divine Artifact
Tools shrouded in mystery. They are mana structures with unique wavelengths. While many are weapon-types, non-combat types for transportation, support, labor, and lifestyle assistance also exist. Their shapes and functions vary widely—swords, guns, scythes, bows, accessories, tools, and devices—and they have specific compatibility requirements for use.
Low-Rank Divine Artifact
Characterized by low mana requirements and ease of use. While performance and versatility are limited, compatibility requirements are loose, making them widely used for daily life and support. Most non-combat artifacts are included in this rank.
Mid-Rank Divine Artifact

High-Rank Divine Artifact
Possesses overwhelming power or utility in exchange for very high mana requirements. Compatibility requirements are extremely strict, strongly choosing the user. Some feature special mechanisms like transformation or multiple forms.
Crystal Energy
An artificial energy resource mass-produced by human technology. It is created by isolating and stabilizing faint energy and environmental elements observed around the world and crystallizing them. It can be handled safely by anyone without mana. It is widely used as a power source for airships, transport machinery, lighting, and various other machines.
Crystal Equipment
A general term for artificial devices made using Crystal Energy. Some are utilized as weapons and armor.
Mana
Power generated from mana circuits within the bodies of living beings. The amount of mana varies by individual. It is used solely for activating and maintaining Divine Artifacts.
