Aiden

Last updated 2026-05-25

Aiden was member #22 of the Genius Society and the first to publish his researches to the universe.

Description

If Zandar had never existed, then there might not have been a Genius Society in the world, and mortals would have one less ivory tower on a mountain. However, if Aiden had never existed, then mortals would not have known where the mountain is.

Aiden set the universal laws for the entire cosmos, which transformed it from a distant concept to a tangible, measurable, and comprehensible objective existence. The nine-worded formulae he created replaced traditional algebra and geometry, and still shapes natural laws to this day. He was also generous as the first member of the Genius Society to publicly share his findings. He selflessly shared his talent with others seeking wisdom, propelling cosmic civilization ever onward — When various scientific fields were established, these founders always said they were standing on Aiden's shoulders. Countless mathematicians and engineers in endless Amber Eras had bravely scaled this peak of wisdom, but none had even reached the great man's earlobes.

People named the most fundamental unit in mechanical physics as "Aiden." It wasn't just due to his achievements in the fundamental sciences, but also a reminder to posterity that Aiden, 22nd member of the Genius Society, was the force that moved scientific advancement forward in the cosmos. He had left innumerable legacies, and the stars will always respect and remember him.
