Well, the adephagos was kind of... It's hard to explain.
The ancient people on my world, Terca Lumieres, were the ones who originally created blastia to make use of aer. They absorbed so much that the aer became imbalanced, and the adephagos was kind of born from that. It was like -- a giant vacuum. Sucking up all the aer around it. [ like a black hole ]
[ he tilts his head back. do those words make sense? ]
Then they used a really big barrier blastia [ created by sacrificing Children of the Full Moon, like Estelle ] to seal it away.
This, uh, guy from my time accidentally broke down the barrier, and the adephagos came back into our world.
