The main story in a nutshell

It's the story of a man that experienced early injustice fear, pain, sadness, despair and hatred. And because of that he decided for the first part of his life to live freely, the way he wanted. But everything changed when the WWI happened. He realised that some people couldn't live the way he lived and so began his journey to learn why things are that way and what caused it. But this man was born with something else. He had powers. He used them to have a better experienced of the way people lived. After years of researchs, even when humanity wanted to make him disappear, he continued his journey. And finally at one point, he find out what he wanted to do. What was his goal in life, and so he decided of the purpose of his existence. But because of what he was he became something else, something more. He became another form of being beyond humanity's imagination. With that the universe opened himself to the man and this man had know a different way to apprehend the universe. So, he began to use his power to answer his fundamental question: Why is the things like this and why ?
But he find out that he was not the only one is this condition of life and so that he left a society to join a bigger society of a new form. So, he could'nt really act like he planned or even wanted. But he adapted and kept using his powers to learn more and more. His main method is using avatars called "Me" that are copies of him, mostly from the last part of his life. But those "Me" are different because of their traits or specialization. That being so, they evolved each in different version of Earth or even others worlds. Each and every unique personal universe are called "Lines". The man also founded a sort of simulation of a society. He put everything he liked and built a sort of simulation game on another world/planet where he became king and leader of a nation. And that is the Xiantia Dominion.
Thence, we got a turn in XD story. There is a big change that is the appearance of a sort new storyline that continues beyond the main one but it is not the same storyline. It is a parallel line that is the following of the main story. But because there is just one difference, we assume it is the main one.
That new storyline began when humanity was transported from Earth to this new simulated world. One of the refugees is in fact a "Me" that will evolved and lived in this nex society to the point where he highly influence the world and even changed it. That is Zaphkiel.
There are two other lines that are the Baraqiel line and the Samyaza line, based on Baraqiel and Samyaza Shemhazai. This two lines are based on the fact that the "Me" has memories of the first dominion and have to evolve in a dominion where different events happenned.
