About those Legion clowns at Nipton: "Vulpes Inculta" is an epic fail. It should've been "Lupus Incultus", "vulpes" means fox, not wolf. I'm guessing he's wearing a wolf head because the wolf is an important symbol of Rome, i.e. the she-wolf who fed Romulus & Remus (Romulus being the founder of Rome according to legend).
Anyway, it's hard to take those schmucks seriously. The only reason why I didn't shoot their heads off is because I feared to break yet another quest.
