"They're all shells. As the living beings of the underground civilization were extremely fragile, they had to live in shells. These things were immortal, but we can't find any detailed information about where they came from in the documents left in the ruins.Based on what we know now, the original carriers are the most common shells, whereas the central carrier which looks similar to them stores many unconscious memories. You can consider it as an original carrier which had been used for many years but had no self-awareness.

"Yes, before we learned how to communicate through thoughts, we often used this method to express our feelings and emotions. But now we don’t use it as much anymore."
