Nutscaves went on to do a few assorted other projects. The population grew some more, and the fortress began Project Beloved Creatures (as well as Project Beloved Objects in Beloved Materials).
Nutscaves was used to test weaponization of 12,600-degree iron arrows, and some other facts about weaponizing heat and magma. (It was established that 12,600-degree iron arrows were not any more useful than any other temperature of iron arrows against goblins.)
Because of the wide array of knowledge I gained while overseeing Nutscaves, I was proudly able to help other players for a long time to come.
The most interesting thing about the fortress, to me, was the way that every time there was a terrible wave of death, the survivors were mostly of two types: the murderers who went on a rampage, but didn't go all the way off the deep end—and the dwarves who didn't care. Dwarves who cracked died. Dwarves who ran screaming from a tantrummer with a battle axe almost always died. The kindest dwarves who helped the others and tried to rescue them, usually died to whatever hurt their buddy. And the next wave of migrants never knew what they were getting into until/unless word got out.
Don't get me wrong. I was horrified. Traumatized. At a loss for words. I needed to know what would happen next, though. So I kept going.
No single survivor at Nutscaves survived for more than about ten years there. The toughest murderers nearly all died eventually to plague, and in one or two cases they got murdered themselves during future tantrum spirals.
Nutscaves went on for several more dwarven years, but its quarantine procedures, defenses, and my own skills as a player had become so strong that nothing interesting ever seemed like it would happen there again. We also seemed to have captured all the wildlife outside the fortress, and the goblins soon feared to invade us. I am sure it was only a matter of time before some more !!fun!!, but soon I grew bored waiting for it. Months after I stopped playing Nutscaves, I realized I should pop open the door to hell at the bottom of the fortress, but by then DF2012 was out, and I decided to move on. My next fortress, in DF2012, was Earthsplatter, where the world was destroyed by vampires.
