I've made some changes to the raws (making dwarves actually tantrum by adding
[PERSONALITY:DEPRESSION_PROPENSITY:100:100:100]
[PERSONALITY:ANGER_PROPENSITY:100:100:100]
[PERSONALITY:ANXIETY_PROPENSITY:100:100:100]
[PERSONALITY:STRESS_VULNERABILITY:100:100:100]
)
So I found a world with a desert that has an aquifer, and built this:
Essentially, the dwarves live off of quarry bush leaf biscuits and aquifer water.
That horse you see there, we replaced the wall with a fortification, and once it died the miasma spread.
We also had all the migrants die, and put their bodies down here to make more miasma and bad thoughts.
We tried to make a thing and the surface, but them tore it down, and it collapsed, killing two.
Then we spiral into tantrums and stress. With only four left, (both parents, one other dwarf, and the baby) We tried to attack the liason to get him out, and he killed both the parents. We didn't get any migrants that spring, and when summer came the two ghosts from the original two that died batter the one remaining adult (not a parent) to death. The kid was born in slate, so he wouldn't have grown up in time.
We had plenty of quarry bush leaf biscuits and drink, but I unpaused it and he died after not too long.
We didn't get any migrants that summer either.
EDIT:
Here is the fort at the end.
