“As a result, the heavens are filled with Telesma while the earth is not. That massive
power will now rain down like the flowing of an electric current. ...Simply put, the earth
will be filled with light. It is via a different route than I had intended, but the result will
be the same. The change is still continuing in this world.”

“That’s a huge mass of the same energy that makes up an angel’s body. If that falls down
to the earth, a ridiculously huge explosion will spread across the surface before any kind
of change can take place!! It was the same with Misha during Angel Fall. If power that
massive is allowed to rage without being controlled, it could easily destroy all of human
civilization!!”
“Yes, it is unfortunate, but only for you. Given the amount of power, at least the entire
continent of Eurasia will be enveloped by the light.”
