Long thought to be just a myth told by ancient mariners, the story of the sunken city of Atlantis began to take on greater credibility when Ruthanian explorers made an exciting discovery in the Sharktooth Islands. Huge cyclopean ruins half submerged constructed atop a reef. The structures were far too advanced to have been built by any of the halfling tribes.
More evidence has been found over the decades, but none of it conclusive. People either seem convinced that the underwater realm exists or that there is simply not enough information to go on. Some of the more progressive within the magical community who study the Feywild and Elemental planes claim to have made contact with beings from Atlantis, but it is almost impossible to discern any hard facts amid the mad ravings.
