I've started painting up my Romans for this project.

"As everyone knows the Romans and the Vikings were fierce enemies. They had many similarities like their mutual love of war and hate of the Jesus people. The differences were greater though.
For examples the Vikings used axes and iron stuff, while the Romans preferred bronze (they didn't have the superior Viking technology) and big unwieldy shields.
The Roman ships (called Tiremes) were a bit like Viking long ships, but inferior. That's why the Vikings won all the sea battles that the Romans and the Vikings fought constantly.
They've both been treated bad by historians. For instance a lot of historians claim that the Vikings weren't alive before 790 c.e. And that the Romans were never involved with the occult. That's why history was banned as a subject during the Roman Empire.
Their common enemies sometimes led the Viking and Roman armies to form alliances to war on people who were badmouthing them. For instance the Jesus people. And historians.
But as both races enjoyed fighting they would often meet up and fight at predetermined locations just for the sport. This is how football was invented."
