Only mention of Germans using sails seem to be during the Batavian Revolt, but they appear to be copying those in Roman ships (if not just replacing the sails in Roman ships that already had sails.)  

They should be licensed under that, yes.

I fixed the helmet using a very rare one I found in 3D.

I'm going to share something I didn't plan to share based on RTW2. Archer, third century. Theory should have a long lorica hamata, third-century helmet, oriental trousers. I couldn't agree on the helmet. It took me many tries. I'm going to use it as a base for drawing it.    

Hello again, back from the wild with answers and questions of my own. I am still constructing possible phrases for the audio pack, irl stuff preventing me from focusing on this until recently. However, I have also been updating all the names of units, buildings and some technologies to have proper Proto-Zapotec (pZ) names.  However, I am stuck on choosing between several options for a few buildings/units, because there is no direct translation possible and I ended up crafting multiple viable alternatives.  If possible, could some of you have an opinion on some of the options I will list below for the troublesome translations?  And if there is any idea for an alternate translation, do please let me know. (Note, the usage of a word for "eagle" is to denote championship, because of the concept of the eagle soaring over all, and because it is part of a larger mesoamerican tradition for using certain animals to denote skills and levels of skills) Scout/Sentry/Stone Tower (this is just for the word "tower"): kinilyasa (“tower, (lit.) nest-trunk”).  Alt. kexlli (“tower, (lit.) standing-stone”).  Alt. kexkiya (“tower, (lit.) raised-stone”).  Alt. sshbexekiya (“tower, (lit.) above cloud”).  I am essentially out of ideas how to represent scout at all, save perhaps use the word for "eagle" to denote far-sight or something. Champion Javelineers: Nazale’chisllo’kiya ("raised/uplifted spear thrower").  Alt. Nazale’kiya ("raised/uplifted thrower," there is no champion slingers to contradict such a contraction).  Alt. Nazale’chis Nikwã-ssiya (“Eagle Spear-thrower”). Swordsman/Macuahuitl Warrior: Nike’yu Kiza’naru’ba’ ("macuahuitl(?) man").  Alt. Nike’yu Macahuitl ("Macuahuitl Man").  Alt. Nike’yu Llo’kex ("Obisidian Man").  Alt. Nadile ("fighter" pZ neologism made from a modern Zapotec word of unknown but trustworthy extraction).  ALT FINAL. Nadile Llo’kex ("Obsidian Fighter"). For those wondering, there is no word in proto-zapotec for towers or any kind of fortification, any kind of fighting man, concepts involving war or weapons, save for a single word for 'arrow' (and the neologism I made).  Even modern zapotec dialects/languages appears to have almost swapped any native words they once had for Spanish loanwords .
