Rome is in chaos. The same reforms that Diocletian had placed to stabilize the Empire after the 3rd Century are starting to grow the same poisonous vines. Infighting and heavy taxation wear down the populace and 6 emperors (and emperor-lite) figures struggle for control. Of these, two meet in battle after receiving two completely opposite prophecies. Maxentius rules from Rome, has rebuilt the fading city, and has been told that today, the enemy of Rome will fall. He takes this to mean Constantine, the junior emperor who wakes from a vision. A vision given to him by a god to paint a symbol on the shields of his men and to go and conquer. But that's the funny thing about prophecy... it's all about interpretation.
