I generated a cute little pocket island with a somewhat long history (the year is 350). Right after it was generated, I noticed that the goblins were off on an isolated tiny island instead of with the bigger main island. So I kept it and started to browse the legends.
Now, I can't quite pinpoint it, but something about the dwarven queen Aban Cloisterfondle seems a bit odd.
It could be the fact that she has been queen for 106 years already, which seems somewhat long in comparison to the other rulers. Or that she worships Rakust the Tombs of Spring ardently. Or that she worships a bronze colossus somewhat dubiously. Or that her third youngest daughter has the pretty title "wife of the moon troll". Or that her last entry in her biography is that she became obsessed with her own mortality and sought to extend her life by any means (23 years ago).
I then looked through her family, and they're all somewhat... off.
Her husband, who has been off adventuring for the last 108 years (and still alive) for instance has a "dark creature bride" as mother.
Her mother became also obsessed with her own mortality and tried to extend her own life. But she did not achieve that goal and just died 84 years afterwards of old age. Her father seems to have been a bit more normal and also died of old age.
While some of her children are still alive - one is the general of the kingdom, another is adventuring, and another seems not to be too extraordinary, two of her kids died at about 2-3 years being eaten by some monsters. And well yeah, the "wife of the moon troll" daughter.
The entire family worships that Rakust the Tombs of Spring, who is not surprisingly most often depicted as a rotting male dwarf and is associated with disease, death, rebirth and birth.
Oh yes, and the outpost liaison... she also had a bunch of hostile encounters with various dark creatures as a kid, worships Rakust the Tombs of Springs and that bronze colossus, but seems otherwise okay.
Oh yes, that bronze colossus is notably because he killed two hundred fourty-two humans and dwarves, I guess. And kobolds. And elves. And thee hundred thirty-six "other kills". He has been around a bit and still at it, though now worshipped.
I just looked at the artifacts and noticed that all (?) of these 271 items seem to be books written by necromancers. Dwarven and human ones.
The island itself isn't particularly evil or sinister. It's mostly neutral and good biomes. In fact, I think the only sinister biome is that island with the goblin town.
There is a dwarven necromancer tower next to the tiles with dwarven settlements. I made a backup of the world and opted to "embark anywhere" and had a quick look before getting slaughtered rather quickly by the inhabitants of that tower. None of the tomes seemed to be written by my dear queen Aban Cloisterfondle. So that might mean that she isn't a full-grown necromancer yet?
While I was at it, I also embarked right onto Paddlebells and went searching for Aban Cloisterfondle. Found her sitting in a room filled with horse cheese, but not looking particularly special. Mountainhome had some interesting fortress design though.
Oh! Aban Cloisterfondle is a descendant (4th generation or so) of one of the first necromancers of this world. The name was Urist Boldswines, and he was the one to do things with the Fated Belch and started the whole necromancy business in that tower. Well, that explains the widespread worship of Rakust at least.
So anyway. I am not too certain what is going on there, but should I try and stick to a fortress in this world until the queen arrives? There are some suitably looking 2x2 spots around with access to dwarves, humans and that tower. Also some suitably looking 2x2 spots with only access to dwarves and humans. And there's of course the tiny island with just access to dwarves and goblins. The elves perished a long time ago.
With my normal speed of fortress development, the queen might just die of old age before it's ready though...
