In the beginning, the Universe created the 2 Ancient Gods, followed by 13 more lights that became the Gods of the other races. The Ancient Gods created the 10 Archangels as their elite generals. They kept the secret that Archangels could become gods—but Lucifer found out anyway.
He rebelled, was cast out, and the Universe granted him Demonic Power. He became the first Demon and the first "Self-Made" God.
Lucifer didn't stop there. He gathered his new race and fought the Ancient Gods a second time. The war was brutal, but as the tide turned against him, Lucifer had one priority: his son, Ezekiel. Before the gods could capture him, Lucifer installed a System into Zeke's soul to act as a cage, sealing his God-slaying energy so it would only release little by little.
Once the seal was set and Zeke was hidden, the Ancient Gods finally overwhelmed Lucifer and locked him away in a realm no one could reach.
As the seal locked, the Blue Fox Spirit fused with the system's code. Zeke was left in the human world as a "Zero," unaware that his father was watching from a celestial prison.
