Mayan ruins have now been found in several locations throughout Florida and Georgia. I also wanted to cater to the whole Atlantean notion. I don't know if the reports of underwater structures dotted all around the Gulf can ever be proven but it makes for great fantasy none the less.
And yes, I was influenced by Sitchen quite a bit in the beginning. However, I have spent the last few years doing my own research and have made many translations and new discoveries myself. I was an ancient history major in college and also have a degree in metaphysics. In terms of a role-playing game, it doesn't really matter if any of it is "real" anyway, only that it stirs the imagination.
the map looks awesome!
I do find it kind of unusual that the game is influenced by Sitchin but it makes sense only because it is a tabletop rpg game.
