"What about the Esper path? It has come to my attention that there are significantly fewer Espers across the starry sky. Why are they so rare?"
"It is because the Origin Will is actively suppressing the birth of new Espers," the Yellow Ancestor explained. "They are simply far too terrifying for this universe to contain."
"That is especially true once they reach the 6th Rank."
"For an Esper, the physical body is merely a fragile vessel containing their Sea of Consciousness. To reach the 5th Rank, known as the Origin Singularity Realm, they must forcibly compress their boundless mental sea until it collapses inward. This destroys their physical brain and replaces it with a quantum singularity of pure thought, allowing their mind to exist entirely independent of flesh."
