The fact that you
removed elf is all that matters in the end, my friend!
So I decided I wanted to build a sky fort and I've learnt an awful lot about more advanced things in DF such as production management. It is also more time consuming to actually get basic things like bedrooms installed because you literally have to make all the resources needed by hand including walls and floors. At the moment I'm considering keeping all the mason/smithing trades underground while things like clothing, carpentry, etc can be in the sky fort.
Already lost a few dwarfs to falling (the fort is about 14 z levels in the air). The ones that survive and recover get the profession name "skyfaller" as a way of showing how they achieved escaping death by fall damage. The only other death was from old age - a rare sight to see in DF.
