INFINITE?!

As he walked through the single island in this World. Covered by calm oceans on all sides, this island was dark, yet serene. Mark pondered. 

The World Space. It was a more developed version of the Soul Space. 

Reol'ran had once told Mark that all living beings, no matter what kind—humans, ants, or bees—all had a kind of mental scape hidden within them since birth. It was supposedly a higher dimensional space that one couldn't steal even if they kill others.

It was in that mental scape that the soul of a living being existed.

The Soul Space that all Demons had, in contrast, was a more evolved form of this formless mental scape. A space where the demons could store souls into if they just knew how to. And the World Space, that Mark now had, was a step beyond even Soul Spaces.

To create a World Space, a mental scape had to absorb a World Core. 

Mark blinked. 

What was a World Space?
