Poseidon eventually outlawed the use of experimentation on the city's human residents and looked to enforce the ban from Atlantis' eleventh recorded cycle. According to an Atlantean myth, a matter which led Poseidon's loathed brother Zeus to visit the city and reprimand Poseidon in-person enraged the Trident King so much that he destroyed the very cycle in which the meeting had occurred. Record of the cycles was not kept initially, and at least one was rumored to have not been seen through to completion.

Poseidon, as the Dikastes Basileus, the Grand Adjudicator, implemented a cycle system for Atlantis wherein the city would be destroyed and reconstituted afresh every seven years if it was judged to be imperfect, a process which could wipe individuals from existence. The city was originally ruled by the Isu Atlas but he was supplanted by his power-hungry father, the Trident King Poseidon, who gave Atlas and his nine brothers the subordinate position of Archon to manage the city's affairs. Historyĭuring the Isu Era, Atlantis was created to be an indestructible repository of Isu knowledge where both members of the First Civilization and humanity could co-exist. The Greek philosopher Pythagoras compared Atlantis' function to that of a library, containing all of the knowledge of the Isu including their physiology, scientific advancements, historical knowledge, culture, and beliefs.
