Atlantis is no more. Since when? None can really say, since no being has any proof to have ever been there, although some greek gods claim they did journey there. What remain of it are giant ruins scattered across a series of islands which may once have been a continent. More ruins lie under the waters, populated by aquatic creatures like triton and merfolk.
New Atlantis is the informal name given by travelers, to distinguish the current incarnation of the city from its mythical counterpart, The largest island is inhabited and has been rebuilt into a beautiful, if somewhat anachronistic city roughly the of the size and scope of a modern metropolis. Its port are constantly filled with ships from distant lands and its market is a booming place where can theoretically find anything. There, human-like beings intermingle with elementals, genies, trolls, giants, faeries and even demons.
