Three thousand years ago, there was a group of elite deities who stood only for good and justice. A deity named Arcana was the strongest among all but she knew her incredible power would cause envy to the others and they would try to dethrone her and her guess was right. A day like no other came ,they came to dethrone her. Arcana had no choice but to fight but the other deities' power combined was too much for her. She knew she was at the brink of death and when that happens ,they would take her power for their selfish gain so she decided to split her power into three cores ;Sternack , Spharach and Sapphire. Sternack, a core of strength and determination to protect. Spharach, a core of accuracy and wisdom and finally Sapphire, a core of reality. This is the most powerful, most wanted and most important of the three. She passed them down from descendant to descendant to descendant and it keeps going on. In anger for what she did, they killed Arcana. A deity ,Orica had excessive anger so they took his power and sent him to the underworld. He became the Demon King Orica . His goal is....to collect the 3 cores and become the most powerful being in the universe.
