Shadow Worlds were a kind of parallel worlds and the most dangerous phenomenon mankind has ever seen that occur each year. Like an infinitely long corridor with countless rooms on each side; there are countless worlds, each with their own bizarre set of rules.
Without a doubt, however, the most dangerous characteristic of a Shadow World is its potential for an ‘Encroachment’ event to occur. Encroached land is smothered in a thick, black fog, and it becomes impossible to know what’s happening inside. Only one thing is certain: no living being has ever entered encroached land and returned alive. It is simply a place where life cannot exist.
Origin of the Shadow Worlds[edit | edit source]
Shadow Worlds are created by the Artemis System recreates the past and turns it into the correct history for the prosperity of all intelligent life. However, the system became the very thing that threathened the world.
Clearing the Shadow Worlds[edit | edit source]
‘Clearing’ the Shadow World prevents it from encroaching upon our reality. If the event of a given Shadow World is based off of a past war in our world—the ‘background’—and the victory of that war consisted in demoralizing the enemy, then the ‘clearing’ would involve defeating the enemy in the exact same manner—this would be the Shadow World’s ‘objective.’ Every Shadow World has its own background and objective, and completing that objective ‘clears’ the Shadow World.
Organization[edit | edit source]
Shadow Worlds didn’t disappear until they were cleared. As time went on, the existing Shadow Worlds would continue to pollute and encroach on their territory. With the thousands of Shadow Worlds available, they were split between Hebrion Academy and the Western Kingdoms. The most difficult instances were given to Hebrion Academy graduate students, whilst the actively enrolled students would often find themselves in low class Shadow Worlds to build experience.
Knighthood[edit | edit source]
According to the rules of Hebrion Empire, any group that can successfully clear a Class 3 Shadow World will recognised for their strength and organisational power, and will be given the same power as Knights.
Accessing the Shadow Worlds[edit | edit source]
A long time ago, Shadow Worlds could only be accessed via Teleportation Gate exactly where the Shadow World spawned. With the technological advancements over the past 30 years, expeditionary members are now able to enter the Shadow World from anywhere using Fifth Circle Space Manipulation magic. In order to participate, all an expeditionary member have to do is select his preferred Shadow World and enter the gate.
Death[edit | edit source]
If someone were to meet their end in a Shadow World, their corpse would become a part of the world. Once the Shadow World was cleared, it would disappear along with the world.
Classes of the Shadow Worlds[edit | edit source]
The Shadow Worlds are divided into 10 levels, and depending on the ranking, the number of deaths in a Shadow World can be estimated.
|Level||Description||Known Shadow Worlds||Notes||Ref.|
|Class 1||The strongest and most dangerous Shadow Worlds.||
|Class 3||Class 3, for all intents and purposes, was the highest difficulty Shadow World.||
|Class 5||From this class and above, those who entered the Shadow Worlds will be exposed to war and murder. Death is a very real possibility.||
|Class 6||This class and below Shadow Worlds are fairly easy that just about anybody can clear them.|
|Class 10||The weakest and least dangerous Shadow Worlds.||Ernste Plains Race||
