Summary0009344: Eerie Murk-covered Raven Thralls appearing on non-evil embark
DescriptionI embarked on a location covered by two neutral-aligned biomes. After a few months, I noticed I had a group of "Raven eerie murk thralls" on the map, attacking and killing each other (is this normal for thralls?). They each had "eerie murk covering" all over their bodies. They attacked my pastured livestock, converting them into thralls which also fought each other. Those in turn attacked the dwarves in my totally defenseless fledgling fortress and killed them all, ending the game.

There was no sign or announcement of any evil weather on my map, so I believe the raven thralls entered my map like normal wildlife. I lost my save when the fortress died, but had a backup from the moment of embark. Letting it run for a season had the raven thralls show up again, so it's reproducible on this embark anyway.

Here was my embark location: [^]
The nearest evil region is a haunted marsh to the southeast, which is two diagonal tiles away on the "World"-scale embark map.

Here is the save I recreated from the backup, immediately after the ravens arrive: [^]
Steps To ReproduceDownload the above save.
The first game had multiple waves of raven thralls appear, so if you let it run a second wave might eventually show up.

Have not tried embarking elsewhere in the area to see if other embarks would be affected, but it might be worth a shot.
Additional InformationGame was un-modded except for removing aquifers.

Probably related to 0008781 and/or 0008724. I posted mine as a different report because I couldn't find any evidence that the evil weather was actually occurring on-site, though I could be wrong.

The forest just to the north appears to be haunted, too.

It's not. I thought so too based on the map, but it's actually a calm rocky wasteland. Double checked with the site finder, there's nothing evil closer than the marsh I mentioned.

Confirming this report.

I was skeptical and downloaded your save to take a closer look at it. It's not a calm rocky wasteland, it's a calm temperate broadleaf forest - which is considerably stranger, as it's showing up in "haunted" colors but isn't marked as haunted. Your fortress is built in a temperate savanna/temperate grassland wilderness. There's no reason for thralled ravens to be showing up here, and the game files certainly don't look like they've been changed much. It's bizarre, to say the least. I've never seen anything like it.

Could they have been visitors, coming from such site that they went through some distant evil area? Roomcarnage had some merchants entering map as thralls already, IIRC.

The ravens were unnamed (just showed up as "Raven eerie murk thrall" on the unit list) and don't show up in legends. They seem just like regular wildlife, outside of their condition and murk-covering.

I reverted the world to before my first fortress embark and tried a second embark in a nearby location, in the same named region. This one is situated on two temperate savanna wilderness biomes. This one has an one additional "world" map square of distance from the nearest evil region (so 3 squares away).

The new embark has already received one "Great Horned Owl eerie murk thrall" before the end of spring. So whatever the issue is, it apparently applies to the entire region. When I get a chance to play this fortress a bit longer I can try to upload another save, if that would be helpful.

Im having a similar "feature". I have setup my fortress in a non-evil "Untaimed Wilds" biome. There is a necromancy tower 13 diagonals away from my fort.

I have a "Honeylock's Fist" roaming around the outdoors, marked as a "Wild Animal". The description states "A hairy humanoid. It has thin wings of stretched skin. Its black hair is long and straight. This night creature was first created by human necromancer Ecod Honeylock of Stillgrip after horrible experiments on the human Or Veiledballs in Muscleconfines in the year 121"

Stillgrip is the name of said necro-tower

It's only ever flyers which turn up, so almost certainly caused by 0008781 which likely won't be fixed until the map rewrite.
