| Synposis of the rest |
There exists a system created by a "God" which controls the balance of the world. If there was a timeline which would have brought about the ruin of the world, then the system would have split it from the world and created a individual world for it to exist in and eventually crumble. The fragments are these instances such that if they had remained tied to the real world, the world would have been met with destruction. In turn, to manage each of these fragments, the God created a unique race which garnered the power of what we know as the shards. Each "Ruler" of a fragment was given a unique soul which contained a power to control the world based on its environment/timeline/etc. The shards and bios stem from the soul as in they were shards of the soul. Mysteriously the race began to die off, and all that remained was the souls, bios, and shards as artifacts of that world.
Now where Fushinsetsu comes into play...He is a survivor of the unique race who is unhappy with the destruction of his fellow-kin, and the management of the system. He was trying to break down the system all while attempting to keep his sister alive....who was dying to the same sickness which wiped out a majority of the rest.
After Arc 2, the story would have shifted to Fushinsetsu's home fragment which was Alice in wonderland themed. Basically, you guys would have met his sister and the strife that was happening in the kingdom. At the end, you would have fought Fushinsetsu and effectively killed him.
After Arc 3, you guys finally get to go home. Arc would have started exactly how Arc 1 started. You guys are arriving at the dorms of a school. Unlike Arc 1 though, this school isn't Ravenwood/RoseHeart...you arrive at your first class only to find that Fushinsetsu is your home room teacher as he introduces you to Armstrong and Brookfield. Unlike, the previous Fushinsetsu through, this one doesn't seem to act the same or contain the same knowledge as the previous.
What you guys didn't know when you completed your fragments is that you accelerated them to destruction, and when you accelerate them to destruction, the balance is dirupted and the real world starts getting affected. Artifacts are commonplace in the Brookfield and across the entire world now. To make matters worse, the Zodiacs, aka remnents of the previous race become a thing to tie us into Arc 5.
Arc 5, you end up at the homeworld of the original race where the survivors exists. Basically its a world that worships the god and helps manage the system. You battle through that world, until you finnaly access the portal which brings us to Arc 6.
Arc 6...is a battle...the entire Arc is a battle....you fight the God and either die or overthrow the system.
If you all died, then GG bad end.
If you overthrew the system which would have still required sacrifices, then there would have been wacky time shit for a happy ending....aka Arc 1 begins again...all of you are going to start at Ravenwood with nothing out of the ordinary.
