Everything looks excellent, and I am anxious to see more.

On the back cover mock-up, I did notice a mention of "ROMAN LEGIONNAIRES." Here in the USA, the term "legionnaires" is normally associated with members of the French Foreign Legion and various veterans' organizations (eg. "Legionnaires' disease"). For discussions of ancient Roman soldiers, the term "legionaries" tends to be preferred. Is this something that might need correcting, or are the two terms more interchangeable over in the UK and Europe?
Best,
Scott
