Auro once used his own research to disappear some human ships in the "Mysterious Big Triangle" region of the ocean!
He also exploited other secretive research to develop his research materials.
Each of these actions didn't involve large-scale harm to human life, yet they all resulted in some chaos and urban legends-like phenomena!
Auro treated the people of Earth as his research subjects.
Daphne and the representatives of other civilizations found this research-obssessed individual laughable. This exile-like person was attempting to research matters that were beyond even the frontier of their own advanced civilizations. Such endeavours were akin to delusional dreaming, an overestimation of one's capabilities!
But when Daphne saw the so-called "gravitational wave" storage device that Auro had sealed, and the related instructions, her complexion instantly changed!
