Introduction
ATLANTIS is a 5e version of "Twilight of Atlantis" for 3e DnD. Its Plato's Atlantis but set in the 3rd millennium BC Not the 9th. The 9th millennium BC just didn't make any sense at all; the 4th century BC nations mentioned by Plato didn't exist in any shape or form then, BUT the 3rd millennium fits very well indeed. The rest of this is pure fantasy and even SOME science fiction. The action starts on the beach below the cliffs of Tel Kabri (the legendary keep on the southern boarder of Phoenicia) at sunset after one of the Atlantean fleets destroyed the entire Egyptian navy in a fierce running battle off the Nile river plate.
