Sounds like something Mayor Lewis should do - legal name change for a fee. I don't know if there's any room for another book in his manor, though. :P
When you first start the game, you have *no idea* how much it's is going to pull you in - how completely immersed in the world you'll become. You might easily choose a frivolous name that you regret. Although I play on PC, I feel for those who don't. :D
