"Secret? What secret? Vonruil asks in a confused tone mixed with a touch of worry.
"My stones, they have already evolved. So, now as long as my heart is beating, I can use them; yeah, the force might be less, but it will still be enough to protect me."
"When did this happen? How come I didn't know or notice?" Vonruil asks in a concerned tone.
"It was when I was held in the dungeons by Klytie. I knew if I didn't get out soon, I would lose my vitality, and then I would not be able to use my stones." Sky becomes quiet for a few seconds. "So, I combined my light, force, and shadow stones. That made all of my stones evolve and become integral to my body. So, now, as long as I'm alive, I can use them."
Vonruil says in a scolding tone, "Sky, do you know what you did? If the power would have been overbearing, you would have died."
