- The World
- The world is known as Pangaea, a single vast continent surrounded by sea, beyond which is believed to lie the world’s end.
- Various sub-races such as elves and dwarves once existed but have now intermingled completely. The entire global population is of mixed heritage, with individual characteristics determined by personal and ancestral lineage.
- There are four nations in Pangaea, ranked by the size of their territories: the northern Pace, the western Shaark, the southern Namto, and the eastern Isu.
- The passage of time is marked by 24-hour days, 7-day weeks, and 360-day years.
- Monsters, dungeons, sacred relics, and magic are all elements of this world.
- All nations share a faith in an unnamed monotheistic religion. Shaark uniquely also venerates the Saint Fatia, its founding figure. Idolatry is forbidden.
- Magic is categorized into two types: those affecting the human body and those manipulating the five elements of fire, water, earth, wind, and chill.
- Although the categories exist, the underlying principle of manipulating objects using mana remains consistent across all types of magic.
- Magic is not about creating something from nothing; it is about manipulating existing elements through mana.
- A strong mental image is necessary to perform magic; the clearer the envisioned phenomenon, the more effectively magic can be used.
- While incantations do exist, they serve solely as tools to help the caster focus on their mental image.
- If there is a substantial discrepancy between one’s mental image and reality, magic cannot be used. For example, it is impossible to cast magic on a distant location that cannot be clearly seen, or through a wall when the caster has no knowledge of what lies on the other side.
- Investigations into incidents are primarily conducted by detectives affiliated with each respective nation.
- In Pangaea, where magic allows for a wide range of individual abilities, concepts such as objectivity and universality are somewhat diluted.
- As a result, detectives employ a variety of methodologies and theories in their quest to solve cases.
- There are no established standards for determining the reliability of evidence or the validity of deductions.
- Organized investigation and legally mandated procedures are also not a focus in this society.
- Consequently, criminal trials depend heavily on the individual judge, who bases their rulings on evidence and reasoning provided by the detectives.
- The protagonist, Van, has written a thesis that is bringing attention to the need for objective and universal standards, logical consistency, and organized investigations, heralding a new era.
- Sacred relics exist; these are items from before the founding of the four nations, with unknown origins and non-replicable effects and durability.
- Dungeons are also a part of this world; they are indestructible structures, themselves considered sacred relics. They continuously produce monsters and items, and adventurers can enter them using a teleporting sacred relic called a Return Stone.
- Electricity and complex machinery have not yet been invented, but simpler technologies like carriages and crossbows are in use.
