I suggest you investigate about the Armenians and their symbol of eternity (8-pointed star), since Georgia (at that time was Russian territory), being on the eastern border of Russia, it is valid to use all its rich mythology (which goes from ancient Babylon and Assyria to the Turks) to support your story line. There you really have a vein that can give you very good ideas. In fact the famous Mount Nemrut is just a little further west in Turkey and don't forget that if you're looking to create an Indiana Jones type adventure there are always at least three sites involved. A third could be the old Romania, for example. The truth is that in ancient times the Black Sea communicated many of these cultures with each other. Oh, and don't go screwing up referring to the Greeks as such anyway, because the correct term is "Hellenic", since the whole Greek thing was an invention of the British East India Company back in 1820. It's thing to look what even the current flag of Greece is a copy of it.
