Unity
The rumbling of the Human Domain wasn't something that could be ignored. It was a trembling that originated in the depths of space, as though a monstrous existence had grabbed hold of the folds of reality and began to whip it about.
There was only one thing that could cause this, and that was a large change in the Domain Barrier.
The Domain Barrier wasn't much of a barrier, it was instead the very Void Battlefield that Leonel had been to once before. The trouble was that the deeper one ventured into the Void Battlefield, the thicker that Anarchic Force would become. At a certain point, it would thicken to the extent that even Ancestors would find it difficult to make their way through while maintaining their lives.
It was possible to make it through, but it required a great deal of effort. This process usually required a large amount of Force that scaled depending on the number of individuals that were being transported through.
