Here's the Wiktionary link, showing the use of Old Georgian and predecessors. I wasn't sure if you were using "people" or "place," so I used the former. Modern Georgian for the place is Apxazeti/Apkhazeti, but Wiktionary doesn't give an older version.
FWIW, I've seen Egrisi in some other places. It appears that Lazica/Lazika was the Byzantine name, Egrisi was the Kartvelian/Georgian name.Lazica: Okay, I think I can use this one. Wikipedia isn't terribly clear on it though, and I would like a better source, but what can you do?
Yeah, wasn't sure if you were going for people or place on that.Nobatia: Again, this one refers to "Nobatians." "Noubadia," which wikipedia tells me is the Old Nubian, might work better though. Then again, that language doesn't fit for this time period. Might just leave it as-is then.
Heh, I just updated Authentic City Names yesterday to fix a table-naming issue, but got caught up in doing some research for the new DLC factions, so I know the feeling.Also you should've posted this earlier while I was working on the mod today. Now I have to go back through my new version and edit it.
