Just for clarification. In Greek, Arete is the word for Virtue(it is pronounced Areti("e" like in "egg", "i" like in "kill")). I do not know about the Latin "Arista", but I know the Greek "Ariston", which means "the Best". I can assume the Latin word to come from the Greek one.
be very careful... greek and latin have mostly.... nothing in common. neither in semantics nor in alphabet.

+100%

from pillaging
I like it a lot but : be careful the +100%

from pillaging here nerfs a bit the raider trait as it becomes less unique.
someone said that said:
again, be careful : you play in erebus, were some gods have avatars walking and some fallen angels are bashing demons or undeads. The churchs can have interest in promoting science. The galileo affair was more a problem of the church being (conservative and more analytical than deductive or experimental) than being anti-science.
For the republic civic :
I like a lot the fact that it becomes like the adaptable trait but : I like it especially if each Xturn you get the choics between 2 traits (oups "political parties") instead of the whole bunch of trait as in adaptative, thus it won't weaken it.
As for loosing the trait when quitting the republic civic... well either you have a new third trait due to republic, that one being changed every Xturn. thus removing it shouldn't be uber-difficult as you were able to add one.
either you don't have a third trait, just modifying your 2nd trait... and thus, why not letting the modified trait in place ?
(I think a penality would be the formation of some barbs units in your territory, in desert or jungle, when you leave republic)
For the rest : apotheoser your analysis are very good and often accurate. Your proposition are nice. and Verily's too.
Be careful : not each religion should have a specific civic : balance, especially in ffh, is not about equality. (oh, and I really like the actual
arete, changing it won't be very good imo : it is a civic about loving kilmorph and her mountains and hills, thus being able to work there more efficiently. It is "arete" as in the greek ethymology as perfection for kilmorph is loving/tending the mountains

)
as for order and Calabim : The Force of civ and FFH is that you may find lorewise explanation for any civic and any religion in combination with any civ.
such as vampires (not undeads : FFH vampires) that are enrolled in order because they devote themselves to fight demons, demons spoiling the lifeforce of the human cattle, making it demonish. For the safeguard of the source of their longevity, brought by need, the vampirics shadow master of the calabims decided that the human cattle and lesser vampires should embrass the order faith....etc
all is possible, even tree-hugging dwarves..
(I just resent Hyborem summoning the mercurians)
