Orizu Claims all these character because they are indeed, their characters.
Duh.
Duh.
In a world known as Grevia, There were Four gods that clashed in a war that would change the lives of everyone.
There was the goddess of Destruction, Oriva, who seeked the end of the world... Landre, the god of Purity, who sought a world free of sin...
Drevas, the god of Darkness, who craved the souls of mortals.. and finally, there was Astria,the goddess who wished to protect the world
Grevia's inhabitants were strongly influenced by these gods, almost everybody worshiped one of them, for good or worse. When the war broke out, everyone hoped for a good outcome, though, it depended on what they thought would be a good outcome...
The Followers of Oriva, were psychopaths who wished to watch the world burn to take power from the ashes of a broken world... The Followers of Landre, hoped to execute all who had sinned to be cleansed of their own sins, finally having a perfect world... The Followers of Drevas seeked to become harbingers of death for their God and giving them more souls to increase their power until they themselves, became Gods... and The Followers of Astria, who hoped to save the world from the foretold apocalypse..
The results of the war were devastating, only one side would get what they wanted and when it was all over the entirety of Grevia was destroyed... continents were cracked and split, oceans became scalding hot, and weather seemed to totally go out of control.. the Aftermath left Grevia in shambles.. but not completely destroyed... The Gods whom have fought to make their wishes come true were all defeated.. each one seemingly murdered.
As the death of the mighty four gods was heard and spread throughout the now Fractured World, The followers of all the Gods still wished to carry out their Murdered Deity's goal, and rumors were even spread throughout the lands that there may be some way to bring the Gods back...
Now present day, the world of Grevia seems a bit less tense... but theres still people out there who wish to please their god... to help them finally finish what they started...
