Only a Master of Dimensions could connect the Real World to their Dimension, and only then could the Dimension truly be used for combat. Otherwise, Wizards skilled in Spatial Authority could easily break in and wreak havoc.
The most unique of the four Concepts was [Profound]. This Concept... well, it was a bit complex. Like [Parallel], it was also naturally Nurtured as the Dimension grew stronger.
If [Parallel] was the Dimension's defensive mechanism, then [Profound] was its offensive mechanism.
This Concept granted the Dimension World many unique and powerful abilities. The Erosive effect of Dimensional Magic Power, for example, came from [Profound]. Additionally, this Concept was quite diverse.
[Profound] could be used to strengthen the Erosive ability of Magic Power, or to create special lifeforms unique to the Dimension.
Especially the latter!
