The death of Gio's mother.
It was indeed the start of everything, but it was also a massive lie fabricated by his father.
"Fifteen years ago, our clan reached the peak of its power. We were truly great, but perhaps we became too big."
Fifteen years ago, two weeks after Gio's birth, the Atmos Clan faced a large-scale attack from a mysterious force.
They charged into the clan and killed its masters. They were far stronger than most of the clan's forces, leading to a one-sided slaughter that barely ended without the extermination of the clan.
Back then, Kyrian did everything he could to save the clan. It was due to his sacrifice that all of those alive today were still able to breathe.
And as the story went, when everything was over, he found his wife dead, cradling the baby in her arms.
