There is, of course, one great pointer to show that the Conorvii were a great warrior race, and that is the fact they were the only civitas to have a legion named after them:
Cohors Primae Cornoviorum, who we know were based at Hadrian's wall for a while. What happened to them after Britain was told to defend herself no one really knows? Did they go with Constantine III do their deaths in Gaul or did they go back to their own region to become the backbone of what became the Powysian kingdom? Or did they, as a generally accepted (but certain not proven) theory goes, migrate to the southwest peninsular to defend against the Irish and give their name to Cornwall? Who knows?
Something is not right. This message is just to keep things from messing up down the road
