25 years as a Centurion in the Roman Legion. Twenty-five-Years! You've paid your dues as a Roman citizen and now it's time to retire back to the homestead. It is nice patch of wooded earth you have set down for yourself - far away from the busy Roman towns, the politicians and their indulgence. It was time to live your days out in peace. Now its the crops to be tended and the horsebacks to be broken - that's all the adventure you seek.
On the frontier the Roman legions have been broken. The Empire is in turmoil and the Germanic barbarians have pushed back the Roman cohorts who are spread too thin along the border and are now in a pitched retreat.
Your neighbour and friend, Centurion Sergius Aemilius has been called backed from his home to bolster the Legion's on the Germanic front. In his haste to rejoin his cohort, Sergius has left his home vulnerable to incursion.
Across the line the Barbarians have broken through, past the Legion's and are bearing down on your lands and those of your forebearers.
