I'm sorry if this has been up before, but I've been away from Ars some months.
So, I've been thinking about something in Ars. For longer campaigns, and I mean long campaigns, Mythic Europe would reach the point when plate mail armor start to appear, and then, gunpowder.
Anyone know at what points in history these technologies appeared? Any specific years?
And what about Verditius? Could they invent gunpowder and plate mail?
