With the Western Roman Empire now under Marcellus' control, and his legions being deployed to the frontier in an attempt to expel the barbarians from the borders. The Empire now found itself in a newfound state of security. So much so that despite Marcellus' previous march of terror, the common people were beginning to flock to his side in support.
The most controversial piece of factual propaganda spun against him was that during his rebellion he butchered a town who refused to hand over their supplies, and used the fear generated from that event to compel the others to do the same.
As for the rest of the propaganda wielded against him by the patricians, it was mostly lies and slander. However, surprisingly, in recent days, the rumors regarding his alleged mistreatment of Placidia were being countered by an unknown force.
