Hailatedum. In the language of the ancient civilization, it meant ‘Sage’.
In the ancient times, it was the name of a civilization which dominated an era. It branched off from the Ancient Humans, but from a certain point onward, it somehow became the main branch instead.
"Colossus Civilization," "The Miraculous Era of Gears and Steam Engines," "The Inconceivable Society Where Everyone is a Wise Man." There were countless other names and glorious titles for them. In that era in the distant past, they and their creations were once commonplace around the world.
As the most advanced society then, they dominated the entire world. Massive floating islands and towers amid the clouds unveiled the secrets of the sky. A giant barrier erected on Island Turtle became an underwater city and colossal Titan Magic Statues were the guardians of their home. Even the Dragons had to remain humble before their wisdom and strength.
