The phenomenon of the whole human race being transferred to an alternative world after the suddenly collapse of earth remain a strange occurrence that the whole human race are not able to solve up to this point after living and surviving in this alternative world for more than three centuries. Human with their strong capacity of adapting to different situation has come to term with their current situation and live with it while forging a new path for themselves.
The first one hundred years in the alternative world for human was a nightmare called the Dark Age, there was no rest for anyone as every human was being hunted by other races in the parallel world for different purpose. The uniqueness and diversity of human intrigue these other races that they decide to find out the makeup of human.
After being subjected to the harsh reality of this alternative world, with the tenacity of human to adapt and survive, they break free from the oppression of the other race in the alternative world building a stronghold for themselves and ensuring that the majority of them won't be subjected to the cruel reality of being prey to the other races.
But human only become united when they are facing a common enemy, but the moment they no longer have a common enemy, they become their own enemy. And this is one of the things the other races discovered and used to their advantage.
Humans are a greedy and insatiable being that will go to any length for their own selfishness and won't care harming their fellow neighbour just so that they can get what they want and the other races utilized this well to their own advantage, promising wealth and authority to some member of the human race as long as they provide them with some human for their own experiment and with the assurance that they will also benefit from the experiment being carried out on human.
Thus, human trafficking and slavery re-emerge within human in the alternative world and underworld syndicates took their root again in the alternative world with the strong families deciding the life of every human, causing rebellion among human and weakening themselves against their enemies that lurks in the shadow waiting for the opportunity where human are at their weakest and take them up in one swoop.
But during these tumultuous times, certain group of human discovered something about their Spirit and Soul. They realized that it contains great and unfathomable power that are yet to be harnessed by them and if every human can find a way to harness this power, they will become a great force in the alternative world and build their own territory that will rival that of the other race in the parallel world.
Through blood and sweat, human were able to produce 15 men and women who unlocked the power within their Spirit and their soul, becoming the heroes and heroines of the human race, fighting for the right of every human to become free from the oppression of other race and the of the great families in the human race.
The uniqueness of human spirit and soul is to the point that, everyone's Spirit and soul mark and attribute is different from the other, and with the unlocking of their Spirit power, they not only have strength, but also knowledge on the uniqueness of their soul and how to further improve themselves and continue growing stronger.
Each Spirit has its own perk, after unlocking their Spirit power, they also unlock various professions, ranging from combat class to non-combat class and each one is granted a soul equipment that is connected to their being and can only be used by them which further empower them and make them stronger. Enabling one person to be able to stand foot to foot with hundreds of armies.
At the end of the human Dark Age in the alternative world, the Human Alliance with are the 15 heroes and heroines forming the governing body that see to the affairs of the human race and also as deterrence to external forces with malicious intents.
After a prolonged fight from external, and internal, the 15 heroes where able to gain a larger foothold for human, expanding and putting other races at bay and establishing the Human Alliance in the parallel world with the 15 heroes forming members of the cabinet.
Though the great families has been suppressed by the 15 heroes and heroines, it does not mean that their ambition to be lord over everything has reduced, in fact, it burns greater alongside the passage of time being fuel by their greed to become like the 15 heroes and heroines and controlling the human race and if possible the great expanse of the alternative world.
Due to the fact that the 15 heroes and heroines want the human race to be able to sustain itself, they distribute the method to unlock Spirit to every human and because of the harshness of the method, it causes a lot of loss without bearing any immediate result.
Human were forced to look for other alternatives to unlock their Spirit potential or reduce the harshness of the method the 15 heroes and heroines released to the public which will be compatible with every human spirit. After many efforts, human had a breakthrough and find a sure method to unlock their Spirit potential.
It was discovered that there is a Spirit root in every human and to unlock their Spirit power, the Spirit root has to be activated, after many further researches, a time in season and an optimal period and age for the activation of the Spirit power was discovered and that period was called the Spirit Affirmation Ceremony.
Every teenager as the age of 12 must conduct a Spirit Affirmation Ceremony the moment they became 12 years of age as that is the optimal age and period to carry out the ceremony. Though doing it after that period, does not mean their Spirit root won't be activated, the outcome is that the effect and potential of the Spirit root will be low due to it not being the optimal period of the Spirit root activation.
Equip with this power and knowledge, the great families that has been hibernating all this while begin to awake into prominence and executing their agenda of being the lord over the human race and taking over the alternative world. But with the help of the 15 heroes and heroines and the Alliance army of Spirit Ascenders, their ambition did not come into fruition, but they become the cancer and tumor of the human race, forming the Great Alliance and fighting the Human Alliance both in light and shadows.
The alternative world becomes the survival of the fittest and the battleground of many races, yet no one knows that every of their actions are within the scope and calculation of some higher entity and unless there's an external variable, everything is within their grasp and there is a greater war going on among the higher entities over who reign supreme – either the light or darkness and whoever have more followers in the Parallel world will have an edge in the Legion battle that will determine the fate of everyone, but still there is a higher being of light, that has seen the end from the beginning and every variables are within his scope even the decision of the higher entities.
