Dwarf Fortress

Ten year old fort in a metals-poor area. Thus, trade was essential, for what is a dwarf without access to metals? Unfortunately my nobles had annoying demands and export prohibitions on key stone goods, so I mostly ignored these and decided that I don't care if my nobles are irate. Those gushy noble bedrooms aren't going to pay for themselves.

Well, years later I finally got around to assigning a captain of the guard, and shortly after I noticed that my 20-cage dungeon was full. Reports of injuries from beatings and soon my two-bed hospital was overwhelmed. Years of export violations finally caught up with us, including the Queen. Production collapsed as key dwarfs were jailed and injured.

We will recover in time, but what a mess! I didn't expect to see that much fallout.
