When I expanded my little oasis into an outpost and started mining the top of a nearby mountain then attacks started coming from on high. After a while an orc camp showed up right as a defiled church was built… right by one another. They started into a pretty big brawl up on the mountain top!
Here’s the save game if you’re interested!
Also it’s a pretty good little outpost. 33 Hearthlings and running as well as I’d expect. Building up a new, interesting town square with a tall tower. Great place to put down all of the nice things the little Hearthlings are crafting!
