The pyramid that they formed is invisible of course. But it is very important that they position themselves this way. It is so that the artifact that they are building won't collapse from an imbalance of spatial compression. At least that's what Soverick said.
They understand what he means and they agree with it. The spatial compression tangent is just one of the things that need to be in harmony for them to successfully build this artifact. There are a slew of other factors that need to be balanced too.
This artifact, or its nascent form, is a sphere of energy and matter in a state of transformation flux. At the very center of the sphere is a white core. It is the authority of the Celestial Supreme. It is the foundation of the entire artifact. All the pressure of the other layers of the sphere rests on it.
Fortunately, it is very durable so it won't break. If it can serve as the foundation of a whole divine plane, produce Authority, and maintain the production of divine energy by making mana available to the gods, then it can surely handle being the foundation of one world fragment.
This Authority of the Celestial Supreme is also the major point of anchorage for Legion. Without it, Legion will have no control whatsoever over what they are building. In that case, they won't be trying to build an artifact. All they will be building is a very powerful bomb.
At the very edge of this sphere is a thin and compressed ring of light. One can see energy in the form of light accelerate around the ring of light. This acceleration of energy is the basic function needed for the advanced function of high-energy transformation.
The ring of light is stable just like the authority of the Celestial Supreme. This band of light doesn't move physically or spiritually. But its function causes the entire middle of the sphere to oscillate. As the world engine, most matter and energy transformations into power occur within it. Legion-1 is the one operating it.
The innermost and outermost layers of the sphere are pretty stable. It is the middle of the sphere that needs a lot of their attention. This middle requires the effort of both Legion-7 and Legion-2 to give it form while both Legion-1 and Legion-9 try to keep its budding form together so that it doesn't collapse.
A collapse of the middle layer is a very bad thing. It is a very dangerous thing. The devastation that has occurred within the inner world will testify to that. The inner world changed because of the explosions. It is also why Soverick has died once and why the tree father has almost died three times.
Legion-1 bore the bulk of the explosion when the tree father was at risk those three times. Legion-1 had to take the brunt because the explosion is not the mere sudden discharge of energy. The laws of the world, including space and time are affected by the explosions.
The death of Soverick has confirmed that anyone who dies in that explosion might never be able to resurrect. If not for the fact that the Soverick that died is just a shell and a clone of himself, then he would be lost forever. The tree father is not ensured yet so he is at risk.
Legion didn't want to risk the tree father at all. If they had their way, they would have used someone else to test the artifact. Unfortunately, they couldn't get an entity that is innately capable of energy transformations. So they did everything they could do to make sure that the tree father survived.
Surviving the explosion of the middle layer is not an easy thing to do. Even Soverick who has always been quick to escape when he notices something wrong died once to it. He was too slow one time and he paid the price for it.
Legion-1 and his inner world have suffered from the 3 large explosions and the 5 small explosions. If not for the fact that the world is the domain of both Legion-1 and Legion-9 and has also been strengthened with cosmic energy, then it would have been destroyed already. That's just one of the consequences of trying to turn the inner world of a world beast into a world fragment.
They could have built the artifact outside Legion-1. They wouldn't have to always take the brunt of the explosion but Soverick maintained that it was a must to do it this way. It is so that the world fragment will be organic and hence be a part of their existence instead of being an external object that they have limited control of.
This artifact has proven itself to be very difficult to build. The middle layer of the sphere is the core both in terms of function and difficulty. It is built of cosmic energy and law fragments plucked from the law matrix.
Cosmic energy is coming from Helios and into the Authority of the Celestial Supreme beneath it. The tree father then pushes the cosmic energy out of the Authority of the Celestial Supreme where Legion-7's tentacles nab it. Then Legion-7 weaves it together with law fragments all according to the instructions of Soverick to create the middle layer.
Soverick's job is to oversee the entire forging process. It is arguably the most difficult job. His mind and that of the other clones that couldn't be here are working full time on making massive calculations based on what he sees. But the difficulty of his work has only been lessened slightly despite the immense assistance he is getting.
His eyes track the energy flow and change while he transmits his intent to the other three. They don't need to speak. They all know what each other is doing, and what they have done. Thanks to Soverick, they know what they should do and how it could affect the entire system.
Everything is in a state of delicate balance. It didn't come easily. They acquired it through synchronized effort both mentally, spiritually, and physically. The balance is needed if they are to succeed in building their own law matrix. Even if it is a facsimile of it.
