Generate a world, export legends, if the "how do you really cap site pops" thread is anything to go by it should give much more reasonable populations.
Not bad, one world had the gobs getting wiped out so I aborted and got a world which had a fortress show up and remain intact so I let it gen the full 200 years, said fortress I was watching turned out like so:
6: Abostosbub, "Agehated", dark fortress
Owner: The Curse of Stigmata, goblins
Parent Civ: The Speechless Dungeons, goblins
lord: Mawada Flankbearded the Faint Fortune of Salves, elf
48 elves
39 dwarves
11 humans
1 purple fiend
233 goblins
31 elf prisoners
34 dwarf prisoners
12 human prisoners
Overall world pops:
5462 Dwarves
2851 Humans
18668 Elves
8635 Goblins
201 Kobolds
Total: 35817
There are three dark forts with over 1k pop (1337, 1357, and 1663 respectively) but interestingly said forts don't have prisoners or indeed anything present
except goblins, no billion trolls, no 9000 gobs, and the only forts I saw with prisoners actually had far more reasonable populations, the one I posted above and this one... wait, a pit with prisoners?
100: Urardost, "Malignrhythmic", dark pits
Owner: The Monster of Clutching, goblins
Parent Civ: The Scalded Fiend, goblins
lord: Kivish Amazegalley the Hateful Mob of Ferns, dwarf
59 elves
14 humans
35 dwarves
60 goblins
20 human prisoners
49 dwarf prisoners
57 elf prisoners
Neat!
The really interesting thing? This world looks like the type that would normally end up soaked with a billion goblins:
Look at all that purple!
