Lost Island of Atlantis - New world/vacation spot and Mythology and Fantasy creatures all in one!

@cjose @Dannydanbo Those ideas sound really great. As for accessing the ruins, I think it could be nice if there was an island that you could find (through learning about the culture or some such, like dannydanbo said), with a couple areas, and then a few more if you find some passages by scuba-diving? There could be a part that is completely sunken and a part that is in a cave accessible only through an underwater tunnel or some such thing. Just to keep with the idea that Atlantis is supposed to be sunken, and give some access to people who don't want to scuba-dive but still want to explore a little.
