Turned off (semi)Megabeast caves, titans, night creatures, and HFS, as well as "beasts dead for stoppage". 10k year history. Otherwise, the same as a basic pocket island. World started in The Golden Age and genned 10k years of history in under a minute, going through The First Twilight Age, The First Age of Fairy Tales (which has one event: the abduction of a human by goblins.), The Second Twilight Age (also quite small), and ending in the Second Age of Fairy Tales.
Turned HFS back on with 3 types. I'll kill them if I get Age of the Demon or something. Turned civs down to 1, set popcap to 0: hopefully this means mortal dwarves will spawn and die... Nope, Age of the Dwarf. Harsher measures required...
Put starting civs to 3, in the hopes they'd start a merry little war. Turned the world into an Arrakkis wannabe by setting max rainfall to 0. Rapidly swung between twilight ages and ages of fairy tales, spending most of its time in the Fourth Twilight Age before ending in the Fourth Age of Fairy Tales.
Same as above, but set the world to "Lightless Yuggoth" by reducing the max temp to -100 as before. World entered the Goblin Age and never looked back, ending with 75 historical figures, 43 of which were dead. So, if the previous value of 12 FBs is accurate, about a score of goblins. Tough little blighters.
As above, but civs to 1, forcing dwarves: 48 Hist. Figures, 22 dead: I don't know why this didn't register the Age of Death! I can start in Dwarf Fortress, Adventurer, or Legends. Legends reveals some FBs, some dwarf gods, 22 dead dwarves (the last of which was born in 3 and died in 158 of old age, outliving one born in 14 by 49 years and her husband who died in 77 by 81.), and a mass of Blizzard Men. Her story is kind of interesting... last dwarf alive in a frozen wasteland, constantly being attacked by with and escaping from the Blizzard Man who ate her husband, the last king of her civilization, descending into the depths of the world to tame Elk Birds, jabberers, and all manner of other creatures to aid her in her fight...
Could it be that the Dwarven Gods are keeping the essence of dwarfdom alive by their presence in the Legends list?
