Excellent! I thought about a Civics connection, but I need to play more of the new M:C to understand how they unlock and progress. If I recall rightly, books start being fairly reliable luxury goods about 1000-1100 AD in real European history and I wouldn't want to get them into the production pipe too soon. Yes, there were scribes fairly early in some places, but the illuminated manuscript bound into a book as we understand "books" aren't a very early innovation. The Book of Kells for instance dates from about 800 AD and represents a very early version of illumination, but AFAIK the Book of Kells wasn't made as a luxury good. And the finest example of a full-blown and documentable luxury book, Très Riches Heures du Duc de Berry, dates from 1412-1416, which is at the tail end of the Medieval Period. Très Riches Heures du Duc de Berry represents the the zenith of illumination, just before it becomes displaced by the printing press (although arguably block printing existed all along and was used extensively in the Byzantine Empire).
