Once upon a time, there was a Roman general, in charge of a garrison on the outskirts of the Empire. It was the middle of the fourth century, and he could feel the earth shifting under his feet, so he called his lieutenants together and said, “Things are changing. The hordes are approaching, and the people are afraid. They’re losing trust in our ability to protect them, so we’ve got to sharpen our methods, and sharpen our spears. I’ve investing in some new weapons, and I’m going to try some new ways to communicate battle plans across the legion. I’ve also been reading about the latest in warfare techniques, which I’ll be implementing little.
“But rest assured,” he continued, “There will always be a Roman Empire. And there will always be Roman legions, generals, and lieutenants, for we provide an invaluable service.”
