Started as Y'laur in a game I was playing offline (URU) When I went to sign up for a virtual world I decided to use it but change it to Elaur because I figured people wouldn't be able to pronounce Y'laur.
I love the "au" look and sound (two of my kids have "au" in their names and the others have a's and e's) And it's very similar to my real name, which makes it easier for people to transition to my real life name.
Well, the "Athenian" part was meant to show an interest in the ancient Greek roots. I associate ancient Greece with many things, from mythology, to philosophy, government, morality, technology, astrology, entertainment... several "firsts" or meaningful evolutions of things that we know today happened then. I suppose it's also meant to identify which part of Western heritage I fundamentally identify with.
I don't strongly identify with the traditional American values, or modern American culture. Not really much with Christianity, the medieval ways, or even Roman ways. I seem to find more and more of my own ways of thinking in ancient Greece.
The 200 is because I've always had some numbers in my name, and it sounded like a nice round number. I've had a lot of people call me Athenian2000, though, much to my chagrin.
