Robin saw Yake's confusion and traced the shape of a planet with both hands.
"Intelligent planets in the Multiverse give birth to a Planetary Origin, also known as a World Origin."
"Absorbing its power wholesale is equivalent to enslaving an entire world. You can only slowly erode its power. At first, your strength will rise quickly, but the more planets you enslave, the heavier the burden becomes.
