The serum worked, and Orin was able to leave the domed city and swim freely in the ocean. The project was kept secret for a variety of reasons and King Orin insisted on being the first to sample the serum. In truth, these scientists had been experimenting on this type of work for several years preceding the great flood. Three years later, the Atlantean scientist Thorne, developed a serum that could alter an Atlantean's physiology, giving them amphibious characteristics. Using Shalako's magic to protect themselves from the crushing waters, these Shalakites, migrated to the ruins of Tritonis and established a new life for themselves. During this time, Shalako had amassed a religious following who condemned the technocratic methods of the other Poseidonians, and he mounted a mass exodus from the city via the underground tunnels. įor several years, the surviving Poseidonians were forced to remain in the restricting confines of the city. As the city settled on the ocean floor, it came to rest atop the remains of the very meteor that destroyed them. Those of neighboring Atlantean cities however, were not so fortunate, and millions were killed. Poseidonis survived the flood, owing largely to King Orin's dome. This event came to be known as the Great Deluge (sometimes referred to as the Cataclysm). Tectonic plates shifted and the whole of Atlantis sank beneath the waves. A giant meteor slammed into the planet Earth, causing massive geological upheaval. Shalako's predictions did in fact come to pass, though whether Suula was directly involved in the coming catastrophe is subject to interpretation. Shalako warned that if they persisted in cutting themselves off from Suula's grace, then they would ultimately suffer her wrath. Though most Poseidonians praised Orin for his ingenuity, some, such as his brother Shalako, felt that the construction of the dome was an affront to Suula - Goddess of the Sky. The specially treated pumice rock was rendered translucent and was porous enough to allow air and moisture in, but was sturdy enough to fend off attackers. Poseidonis was often the target of vicious raids from nomadic tribes of savages, but the scientists of Poseidonis discovered that they could protect themselves by constructing a dome around the city made of pumice. In the years leading up to the Great Deluge, Poseidonis was under the reign of the benevolent king Orin (for whom Aquaman was named). His secondary headquarters though, the Aquacave, was actually located outside the city. The super-hero Aquaman maintained his base of operations in Poseidonis during the years that he served as the continent's undisputed monarch. Both cities are connected via a network of subterannean tunnels.

Geographically, it lies within the center of the continent, near to the neighboring city of Tritonis.
