Hm....But if I smoosh up caverns...*Sets cavern number to 1* *sees more Dark Fortresses than usual with parameters....
1: coffee (and some giant brown recluse spider webs in the trees?)
2: finger lime (and giant mongoose who was very afraid in first second.)
3: pecan wood (and quite a bit of brown recluse man webs). Looked at wood list available for embark. Tower-cap, yes, but no other underground trees....
4: peach wood logs, (and invisible biome overlap gives me silk despite being embarking on single wrong biome. )
5: citron wood (, and found armadillo sow. A baby could kill one and get the shell left on the ground. )
6: tower-cap logs. Interestingly, had white wagon....
7: tower cap again(, and found first animal person - kestrel man. He climbs trees. And, huh, 16z from surface to magma sea...)
8: palm tree.
9: persimmon wood. I'm thinking that I don't really need to deconstruct the wagon to see it isn't underground tree....
10: apricot wood.
Perhaps this would be better done with multiple dwarven civs, but...I should have checked whether they're usable in the first place, rather, as my nether-cap stockpiles in older fort are available for wall-building, but not wood furnaces, glass furnaces or kilns.
And yeah, no shearable wagon-pullers, so they'd have to be brought by migrants. Though, if one excludes them....I don't recall ever seeing visitors with animals on them. Kiki gets no cats, I guess?
