isolationism would be fun, only a few dwarves are left uptop hiding in the shadows or something, while the others just kinda disappear
An idea i have would probably have to be that, while the miners are going through all the stone, dirt, ect, they find some sort of hidden entrance way to a whole bunch of treasure, like rings and jewels and necklaces, and ends up that it all of it is cursed, maybe some dwarves start going crazy, this could probably go great with the isolationism thing, just an idea if anyone wants to expand on it, or modify it in some way.
