well, yes, we are just messing around really. There won't be any results except to briefly amuse ourselves.

I always assumed the the high period units were called "Chivalric" because the code of chivalry as we know it developed approximately at the start of the high period (I think), influenced by the crusades and literary developments in the stories about Charlemagne, King Arthur, etc. The idea of what it was to be a knight changed from just a loyal high class warrior to a soldier of God and a really classy heroic character. Still, its a bit silly, I suppose.
