[X] Plan Longhouses, Mountain Men, and Goats
and I would love for them to think that the mountain folks are idoits...only for their plan to back-fire as the mountain men figure out the plot and then go on a war-path...of course them getting a elite commander who keeps on leveling harder then normal would be hilarious to read about as they try to figure out what the marker did...only for them to realize we took out one of the largest villages and are pissed at them for fucking us over.
The fact were letting them stew is them thinking they are about to get a barbarian invasion pretty soon because of how badly the loss of 2 plains villages would be for the local economy...and nega-Azel laughing in the background as he explains that if we hand not raided them they would be in a worse position...
so the nega-verse guys would be feeling...conflicted...plus knowing that were coming for them. And if we get the first Copper deposits? Oh boy, that's going to allow us to grow FAST! plus copper armor might not be great or as good weapons...but they would last allot longer then obsidian weapons and tools. Not to mention the fact that if we find tin deposits we would be in the position to become not only Dwarves, but also ruling the mountains. Then we can beat down anyone who tries to take the mines for the metal deposits as well as charging LUDICROUS prices for even a hint of metal to the plains-people.
I'm not sure copper armor is economical, it's a very soft metal and easily deformed. We might be better off with multiple layers of felt armor or even just well constructed leather.
