Diocles, son of a slave.  WHAT?? Say that again.  Diocles, who assumed the regnal name of Diocletian, was the first Roman Emperor to be born the son of a former slave.  He would rise from dirt to the pinnacle of Roman power, yet another of the Illyrian cabal, hellbent on restoring Rome to her former glory.  But rather than focusing simply on military brilliance to accomplish that objective, like his immediate (really all) predecessors had, Diocletian decides to experiment with the hallowed structure of the Roman imperial system to see if he can build a better, more sustainable, mousetrap.
