"It was a time of great prosperity and technological advancement. We had unlocked the secret of unlimited energy at a time when the rest of the world still thought the Earth was flat. But we became too ambitious; too hungry for power. The ocean swallowed us, and Atlantis sank."
The Great Fall of Atlantis was a tremendous cataclysm that saw the destruction and submergence of the world power Atlantis millennia before the Black Zero Event.[3]

↑Atlan used Romulus' status as king in his trident puzzle, meaning he must have been alive during/after Romulus' reign, which began in 753 B.C. The Karathen also confirmed it had guarded the trident "since the beginning and for a thousand years," which means Atlan must have been dead for at least 1000 years, putting the fall of Atlantis and creation of the trident puzzle between 753 B.C. and about 1000 A.D.
