The Barrier for the Inner Region was almost impossible for others to pass through. However, for Gabriel, it proved to be very easy.
What was even better was that he had to go in all alone, so he didn't have to worry about always watching over his back. He also had an entire army in his shadow, so it made things even easier for him.
As he ventured deeper into the Core Region, Gabriel noticed the stark contrast between the Inner Zone and the Core Region.
In the Inner Region, he could at least see some things. However, as soon as he passed through the barrier, his vision had completely gone blank, as if he had become blind.
Not only did his vision, but his other senses were also blocked right away. He couldn't smell anything. He couldn't hear anything. He also couldn't feel any touches.
