"Woooaah! Is this the underground?!" wondered Mao.
"It sure changed, right?"
Apparently, the very world my realm has become has been divided into dimensional membranes, realms of their own. The surface is where we all inhabit, its like the most basic mantle, then the underground became like something similar to a "world inside a world".
There are clouds, a sky, and there's even artificial sunlight and even a moon. Right below us there was a huge garden of beautiful blue flowers, overflowing with Ether and Mana everywhere, there were many Cosmic Soul beasts foraging around.
This wasn't a really safe place for most inhabitants, as this second layer of my world realm had become concentrated with a lot of energy, only gods live here, mostly in their own divine realms anyways.
