Dux is how Mussolini was called under Fascism in Italy, just FYI if the developers are reading.
It's also a Latin word predating Mussolini by several thousand years.
It's also the name of a fabulist whose stories Jean-Claude Van Damme's Bloodsport was based on as well as his eponymous martial arts style, Dux Ryu Ninjutsu.
It's also what you call the top student in a school year. I think that waters down the association enough.
