Here’s the update on my latest attempt. The Geomancer and the Miner jobs really help in building an underground dwarf town. Unfortunately, it still takes a while to excavate, even with the miner.
I dug under a corner part of a river and that feeds the fountain in the middle of the town. It takes a lot of toying with wet and dry stones to get the balance right so the fountain isn’t flooding the underground and the river above isn’t draining.
I finally put some effort into a distinctly Dwarven architectural style and I’m pretty pleased with how the style is working out so far. Unfortunately, I had to instant build to get them to be finished because I didn’t dig deep enough for the height of my buildings.
With the Geomancer’s abilities, I’m wondering if maybe you can just build an artificial cavern over a plot of land so you don’t even have to excavate. I might have to try that next. The discussion in my Bunny Fountain thread hints at the possibility of generating landmarks underground that might work for creating ready-made caverns.
