I'm making an Imperial and hit a roadblock in what to name my character, I want it to fit with the imperials. I've notice the imperials have a broad range of names ranging from vulgar roman Latin to other types of Latin so I figured just to give my character a Latin type of name maybe just a typical medieval English Latin one but am I doing it wrong? are the imperials based off one name base like roman Latin, or are they all mixed up?

Roman or Latin, it doesn't matter.

Tiberius Milkdrinkus

Take some Latin and maybe throw in some Italian if you think it fits. Hard to go wrong.

Mine's name was Septimus Ocala. You can use it if you wish; I deleted it.
