['Power Core' Created!]

"..."

The voice inside his head made Khal feel more and more that his belief was right.

What was a Power Core? The very first time Khal saw the pebble inside his bracelet, he thought Power Cores had a mysterious and complicated origin, but with time, he realized he was wrong. Power Core in truth had quite a simple background; they were the cores or with another name the jewelry place inside the Artifacts.

To put it simply, Power Cores were simple pebbles just like this purple stone at the end of the flute; nothing special at all, but just a plain crystal that can be found everywhere in this world.

A jewel.

However, the biggest question here was how did these pebbles, this jewelry get the power in them, obtaining the title of 'Power Cores'? As Khal thought about this question, it finally seems he found the answer.
