The space of the secondary dimensions was a bizarre world composed of various planes, and its rules were different compared to the main universe. Most of them were not suitable for the survival of creatures from the main universe. Some were formed naturally, while some were created from the fantasies of high-ranking mages.
If the main universe could be described as the branches and roots of a tree, then the secondary dimensions would be the leaves and fruits, and there would be a nutrient connection with each other—energy.
Researchers in the universe had created a world view model for the secondary dimensional space, which looked similar to a picture of countless bubbles stacked. Each bubble represented a secondary dimension, and the space wall of each bubble was much weaker compared to the main universe; one could jump and shuttle around frequently.
