Well i'll start off with saying i'm a big fan when it comes to Greek mythology. the 2 igns which i'm conflicting between them are : Menoetius ( Titan, god of Violent and Anger ) and Pallas ( Titan, god of warcraft ) i do know that there's a level 200 NL called Menoitios, this is why it's even harder to choose. take in consideration Pallas is written with x2 i's if it matters
I'm no fan of Greek mythology... but I guess consideration may be given on the gender you would prefer for the character, how easy it is to cosplay as either one of them, and the class. To state the obvious, make sure the names aren't taken.
If NL, why not name him "Hermes", the messenger God? They're both athletic and fast. Other than that, maybe Menoetius would be much more suitable.. Pallas would sound good for warriors (blacksmithing)
if you ask me pallas sounds better - short and easy but i have no idea about the mythology of them lol
