Belisarius. Just one name required, in the realm of other one-named immortals, like 'Jordan', 'Ali', 'Caesar', and so on. But this guy is a one-named mystery, worshipped in the ancient world, forgotten today. When we meet him in this episode, he is not let legend, simply a Thracian boy that makes his way to Constantinople, enters Justinian's bodyguard and in a heartbeat is a 28 year old Magister Militum Per Orientem, leading an invasion fleet to Carthage, to punish the Vandals for their mortal insult to Roman honor.
