Have you ever seen anyone with a name related to some work of fiction like that? The best example I have is a girl I went to Sunday school with named Ozma. Not after the Final Fantasy IX boss or the Ra-seru but after The Wizard of Oz. This kind of stuff has been around for a long time (LOTR, D&D, Star Wars) so I'm surprised I haven't seen more of it.
In terms of real names, I don't want my son to have a boring name but I don't want it to sound stupid either. Might pick one out of history that sounds half normal.
