Truth Seeker Devianne:
Each process of Atelia refinement is completed by a specific demon in each area. They are difficult to find. These demons are completing each refinement process using their abilities.
I also found out why the demons are coming to the refinery. It's the Dimensional Energy. Dimensional Energy is somewhat of a delicay for demons.
When the demons absorb Dimensional Energy, the large amount of force applied upon the energy crystallizes it into Atelia.
"Really?"
