Basic Settings - v-rus' Translations

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.

2. Magic

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.

3. Investigations

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.

4. Miscellaneous

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.
