In the ancient days before all lives were born, even space-time didn't exist.
The world was opened up, being in a state of chaos. Countless strange creatures were naturally born from it.
Thereafter, with the Big Bang, development started amidst the chaos, producing the initial space-time.
However, the strange creatures that experienced the Big Bang weren't destroyed. They landed in the new universe and scattered out to all areas.
Some treasures were born before the world and tended to possess countless mysterious abilities. They could neglect the existing rules in the world and possessed their own strange abilities with their own law of causation that would catch others unaware. They had their own judgmental rules.
Once activated, they could, for example, ignore most defenses in the world and immediately capture a target.
There were stories of such treasures in various myths and legends that existed in different civilizations on Earth.
