Some five hundred years ago, in what the future would call 43 AD, the armies of the Roman Empire broke through Britain's gates.
Apart from Scotland in the north, the entire Island of Britain fell.

Several decades later, a small city west of Camulodunum rose to prominence, gradually replacing the old capital as the administrative seat and military hub of the Province of Britain.
That small city was what they now knew as Londinium.
After the third century AD (AC.200), Roman emperors came and went in rapid succession. The army wielded excessive power, frequently installing puppets or murdering emperors to seize control, while the bureaucracy was corrupt and inefficient.
