If you want to know about how the ranks or grades of Resonant Class and Soul Depht, you're in the right place.
(It's not the full list and there maybe be changes in the future. Everything that's listed here is what has been mentioned in the story thus far but hasn't been explained yet)
Let's start right away!
There are two different terms to call a Resonant's rank; the given by system's name and by the League's.
Here's what the system named the Resonant rank:
Neophyte
Disciple
Herald
Apostle
Saint
Transcendent
And here's what the League referred to the names:
Beginner
Elite
Master
Grandmaster
Lord
Transcendent
For the Soul Depth names, both the system and how people refer to it is the same:
Surface
Shallow
Profound
Twilight
Abyssal
Crevasse
Void
Also, there's also a category for adressing a Resonant's stats (Strength, Speed, Intelligence, etc) that's issued by the League:
Human-level
Genius-level
Superhuman-level
Unparalleled-level
Though, this category won't be explained that deep because it's unrelevant. I just put and mention this in the story for worldbuilding purpose but actually it's not that important.
Now we get into geography! Are you ready? No! Nice!
The geography still used the Earth's map but with some changes and distortion here and there (I will attach the map later when I finished designed it. For the time being, you can easily imagine the world map, right?)
City/Settlement: A place where humans resides (obviously). They are scattered around the world but are fewer than a number of countries we have right now.
In this story, there are approximately 27 cities that has been rebuilt around the world. The most advanced and the first city ever build by humanity after apocalypse is Haven Liberty.
Here's the list of cities (only the famous and will be mentioned or relevant to the story) by region:
Europe: Haven Liberty, Majesty
North America: Oberios, Apollis
South America: Huantinco
Africa: Omark, Jessnal
Asia-Oceania (Pacific): Orien, Ryuunokuni
Land of Mystic: Avalon
That's all for now.
