The Amurites are derived from Patria, but the same could be said for every other human civ (although the Lanun were never really more than nominal vassals when they were part of the empire, and the Elohim were already ancient when they joined Patria). The Amurites were formed from scattered tribes of refugees in the Age of Ice, and cannot trace their ancestry back through a Patrian faction any more than the Doviello can. However, the Patrian Emperor Kylorin found his reincarnated wife Eve (Epona in that like) among them, and so joined them and became their leader. They modeled themselves after his old empire, and recently have restarted some Patrian traditions (like the trials in the Caves of the Ancestors) that Kylorin had come to regret and would probably not like them using.
(In an older version of the lore, the Patria was a name later applied to an ancient people who called themselves the Amurites. Of course, they may have called their land Patria too, as that just means "The fatherland" in Latin and probably Patrian. Kylorin reused the name of his Age of Magic kingdom when he formed a new one in the Age of Ice. I still prefer to think of it this way, but Kael decided to change it so as not to confuse people.)
The Patrian empire was quite large, including all parts of Erebus where humans lived. This probably includes all the human lands of the Age of Rebirth too. I assume the answer you are looking for is The Remnants of Patria unique feature, but that could indicate the ruins of any patrian city in any land.
My question:
What is the meaning of Life?
(As in, what does the precept of Life represent. For example, the meaning of Fire is Passion and the meaning of Force is Balance.)
