Conventfortress had been going well. I moved my temporary living quarters all the way down to the magma sea and then made a set of copper armor and maces. By this point, the zombie ranks on the surface had risen dramatically, and migrants / traders had absolutely no chance to get underground. So I was pretty much stuck with the dwarves I had.
I set up my danger room and drafted the few males into the military (the female nuns had too many babies, bless Armok). Then, disaster struck. At some point during the danger room training, all of the soldiers got their teeth knocked out. All of them. I didn't notice until it was too late, and I certainly didn't have a hospital yet. The dwarves all died from infections - a very severe case of gingivitis. I already excavated a garbage chute into the magma sea, so I dumped all the bodies before they could rise as zombies.
Unfortunately, it wasn't enough. By this point, my dwarves had absolutely had it with their terrible living quarters and diet of plump helmets. The tantrum spiral resulting from the deaths of the soldiers was enough to get the dwarves killing each other, and the sane dwarves couldn't dump the bodies in time. They came back as zombies and destroyed the fort from the inside.
Lessons learned from Conventfortress:
- Don't butcher anything in a terrifying biome.
- Danger rooms can knock out all of your dwarves' teeth. (This may be the end of my use of danger rooms)
- Set up a hospital before training your dwarves.
- Werecreatures can become undead. They keep transforming back and forth between forms when they are zombies.
