My main and alts have very varying styles of name and it took forever to find a name that seem like a real last name for any of them and finally I had to reach back to the days of FFXI and use an old name. Atm I have 1 of each kind of base class so my four characters are
Captain Berengar Shantotto
Darth Sodomus Shantotto
Agent Bojmir Shantotto
Atal'kar Shantotto, Knight of the Republic
