A lot of the places I'm using are unpopulated at 1700AD, and only became recognised locations after C19th Colonialism.
Inhambane (Mozambique) is hundreds of years old at 1700AD, and has a history of Arab and Portuguese settlement / trade. It's been established that it has a population of 5,000 in the game, and, at least with my Rozwi turn sheet, a gazette entry written as Agema fact.
Ba-Phalaborwa (South Africa) has been recognised as existing, and having a population of 600
Umtali (modern Mutare, Zimbabwe) didn't come into existence as a settlement until circa 1900, but it serves my purpose in game as it's near Tete and Sofala in Portuguese East Africa
Jahunda Hill (Zimbabwe) is a nearby geographic feature to a modern settlement, which again serves my purpose in the game.
In future games (or game edits) Rozwi might have Inhambane added to its settlements, possibly. Also, Rozwi may be recognised as having access to canoes and coastal sailing craft (both suitable for fishing).
I'm not saying I'm revolutionising Agema's understanding of the playing position, because its mainly me asking or pointing Richard to an idea and then waiting for him to check / legitimise it in the game. Rozwi was so deficient in any information or settlements to start with, it really was like writing my own game position. Hopefully what I / we have provided for Rozwi will be of benefit to the whole.
Saying all that, my Rozwi is more visibly familiar to Zulu culture / history, it probably bears no resemblance to true Historic Rozwi. But I just can't find much in the way of specifics of information for the tribe.
