In the world of Exatia, all being in this world has an ability that's rank down from [SSS] to [FFF]. For those who got the highest rank skill, they will have a great and spectacular fate. While for those who got the lowest rank skill, they will be put into the lowest ranking in society and would be seen as an item or worthless beings. Such is the fate of those who's unlucky enough in this world.
But that's not the only problems. There's also war of faction is this world. In this world, there's three types of faction.
The first one is the lawful faction, with their white coloured flag with a golden scale picture in the middle of it. They are the beings who will always follow the laws and capturing others who brokes the laws. The example being is the humans from the holy kingdom, magic kingdom, silver dragon, and many more.
The second faction is the neutral faction. They has a huge tree in the middle of their green coloured flag. They won't chose any side kept the balance between the lawful and the evil faction from completely destroying each others. They also follow most of the laws to keep their peaceful life and to prevent most of the serious crimes. For example, The elves and the high elves, the dwarf, the other colours dragon except for white and black.
The third faction is the evil faction. They have a black eyes with red iris on the middle of their flag. Their flag is coloured black like an abyss. They are a being who don't want to follow laws and do everything according to their desires. But, they also has some law in their city, though not strong to prevent many crimes. The being in this faction is the black dragons, the demons, the vampires, the incubus and many more.
But that's not the only problems. They are those who does immense evil that even the demons respect them. They are the people who seek to past the limit of their skill rank. Some people believe there's a rank even higher than the [SSS] rank. And most of them is the great alchemist of this world. They believe if they managed to created life with their skill, they will manage to evolve their skill into the unknown rank. And why do they think so? It's because of the demons race alchemy formula. A formula on how to create a homunculus. An illegal alchemy product that require thousands of beings life. Not only that, many of those with great skill and potential even became the materials for these people. For them, this alchemy formula may open up the door towards the unknown. Though no one really knows if it's true or false.
This cause many races great alchemist to fall and die just because they seek and try to create a homunculus. Only a small amount of great alchemist managed to resist the temptations of the so called greater heights.
With that, many races hates the demons. Even those from the neutral and evil faction hates them.
As the time pass on, the alchemy formula of creating a homunculus became even more bizarre as time goes on. It's reach until they kidnap and torture the people they kidnap. Eventually, the alchemist professions becames illegal and any information related to it being reduced to ash.
As time goes on, everybody except for some people eventually forgot the alchemist professions. Like the people saying, nothing can escape the corrosion of time.
They only remember about how a homunculus is an illegal and an evil creation.
Thus, the alchemist has stopped exist in this world.
Only some demons who's with the alchemist skill exist. Even though most of them didn't know about the skills.
And so on, the world goes on with their way of living their live. Little did they knows, humans has been depending on their alchemy product for a long time.
And as time pass by, humans becames weaker and weaker as more alchemy products brokes.
They were eventually reduce to 5 kingdoms left. Which is the capital city of every emperor.
The five city represent The City Of Magic, The City Of Blade, The Holy Kingdom, The Adventurer City and lastly, The City Of Art and Harmony.
The city of these five country eventually held a meeting to discuss about their grim future, and they made a decision to summon humans from another world to assist them in the fight against the evil faction. Even though they can asked for help from their ally, their ally can't always help them. And thus, this is why the decision was made.
And thus, continue their battle against the evil factions and defence against them.
