The Star-Rotating Half Bitwall was a half bitwall which was incompletely evolved, or it could be said that all half bitwalls weren't perfectly evolved, but the Star-Rotating Half Bitwall was even more unstable.
Its interior didn't even have the rules of gravity, there was no light, temperature, water and life; there was nothing. On the inside, there were boulders which were constantly colliding; a large number of stones in different sizes were revolving around the largest stone.
After Maria's World captured that half bitwall two thousand years ago, it was being transformed since then.
Over the years, Divine Kingdoms of Maria's World had formulated a perfect procedure for the transformation and use of the half bitwall; Mana Floating Island, simple floating device, yarn of light, magic crystal tower, sea crystal and all kinds of technology were developed.
