Caves only form in limestone, which tends to form very fang-like stalactite and stalagmite formations, especially around new tunnels.
Ooo, now we know where to loot for rocks to burn with the iron!
Kidding, those caves are valuable cultural heritage and a nice place to study acoustics, but there should be other limestone hills in those areas.
Didn't we withdraw from all contact with everyone for like a generation?
-New Insights - When we cut trade ties with everyone. This was 24 updates ago, more than 10 generations(we have approximately 50% mid turn updates) and more than 200 years ago
-Harmony in Law - Told the Highlanders to fuck off.
-Healing Magic - Sent emissaries to tell everyone how to not shit themselves to death. Recieved Xohyssiri Book of the Living.
-New Ventures - Established trade to the Xohyssiri.
-The salt must flow - Salt Gift, Metal Worker Trade Mission
-Dreams of Bureaucrats - Xohyssiri Trade ended by war.
-Perculiar Results - Metal Worker Trade Mission
-Calm before the Storm - Metal Worker Trade ended by Suddenly Nomads
-New Connections - Unknown Trade Mission arrives
-Quiet Tensions - Xohyssiri Trade Mission arrives
So...we've been receiving traders, but we've not been trading actively(in the sense of outgoing caravans) with anyone but the Metal Workers and Xohyssiri for a very long time. The only diplomatic contacts were outside coming in, except for the one time we drove by and dropped shitloads of wealth everywhere.
So, you're telling me that one of the most important beliefs of the people, a belief that was established after writing became widespread among the shamans, is not written down? Somewhere?
Also, yes it is possible for our test group to 'get lucky' but read this abstract:
https://www.researchgate.net/publication/249962585_The_Infectious_Dose_of_Variola_Smallpox_Virus
What this basically says is that a single viral particle can cause an infection. Smallpox is rediculously infectious. The likelihood of someone
not catching the virus if they've never been inoculated with vaccinia or haven't had a booster in a long time is
extremely low.
Actually, it's precisely because we think they're important that we never actually wrote them down. Our shamans think something so important can't possibly be forgotten or remembered wrongly, after all, it worked for them!
I mean, yeah, trade is good for this situation and all...
But doesn't salt gift also include sending trade caravans to all the major players? Only instead of haggling over dyes and salt, we just hand out salt like candy.
The mingling with lowlanders part still applies
Salt gifts send caravans to their kings and nobles primarily to impress them. Those are not usually the pox heavy population portions.
