Demiplane

Only those peak Heaven Mages had the power to open a Demiplane. They would use countless arrays to open their own worlds from nothingness. These worlds stood outside of Noscent since their inceptions, not receiving any binding from the laws. The laws of these worlds were an embodiment of the master's will, and these worlds also depended on their masters to function.

There were an endless amount of planes scattered through the void. Even the mages at the peak of the magic era didn't dare to say that they understood the secrets to the endless planes. Demiplanes weren't something that could only be established by Heaven Mages. Among the Demiplanes, some were also naturally born.

Only a naturally formed plane would give Mana Vines a chance to grow.

Demiplane are generaly being attached to at least an Artisan level array (being attached to a Master level array was like using fodder to feed a large Dragon, this was abuse!) who use mana transmission and rune transmission.

Just a Mana Vine alone was enough for subsist a Demiplane.

When a Demiplane was first established, the first step would be to set up the living areas of the four elements. This was the foundation of all Demiplanes, because without these four basic elements, a Demiplane wouldn't remain stable. It might be destroyed in the Netherstorm, or be swallowed by the chaotic passage of time and space.
