I tried to embarked to sinister surrounding, I hoped to encounter some skeletal animals. First spot crashed the game between selecting stuff to bring and the starting text message. I tried 3 times and it always crashes. So I chose a nearby sinister spot, and successfully embarked. The location is rather disappointingly normal. Grass, river, a few trees, some normal animals. The only "evil" thing I got so far into the game are dark gnomes, who stole some booze before I got them locked up in a dry murky pool (from which they escaped after rain refilled the pool 1 year later).
The first abnormality occurred right on embark. It gave 14 cave-in messages in a row. I checked with reveal.exe and discovered that it was the bottom of the magma sea caving-in into HFS. Moreover, the last cavern is generated below the magma sea. The effect is that all the magma and the water are all gone, leaving only a few isolated pockets. The edge of the map has both cavern water and magma sea magma constantly generated, mixing, and falling down, continuously creating mist, and there are some obsidian walls on the very bottom level. All water and magma fall directly into the pit.
I embarked on level 144, the lowest level is -25. The intermediate levels of interest are shown below. See how messed up things are:
Highest of map | 168 |
Highest above ground | 153 |
Lowest above ground | 140 |
Highest point of the adamantine spire | 128 |
Top of the 1st cavern | 122 |
Highest point of semi-molten rock (yes, it goes all the way down from here) | 95 |
Bottom of 1st cavern | 88 |
Highest reach of the HFS, through the 2nd cavern | 34 |
Highest point where the pit can be directly seen, inside 2nd cavern | 17 |
Lowest semi-molten rock, adamantine spire, 2nd cavern floor, magma flow | 1 |
Large areas of magma | 0 |
Lowest water pool | -13 |
Lowest magma pool | -15 |
Bottom | -25 |
All other games had 3 caverns, but here I can only count 2. Not only the bottom cavern is completely messed up, the first cavern is not completely normal either: it is full of normal grass. Subterranean trees and bushes but above ground grasses. The other cavern is normal with moss.
Not a bit of water in the first cavern.
Perhaps the entire 3rd cavern caved-into the pit the same way the magma sea somehow did.
In terms of minerals, fairly normal close to the surface, but no mineral is present below 84. Instead there's an unusual number of emeralds. Prospector gives:
Tetrahedrite: 24791
Emerald: 28006
Microcline: 132000
Slade: 567129
Making emerald the 2nd most abundant mineable rock deposits. (not counting layer fillers)
The actual game is fairly simple, there's ample iron ore on the surface alongside flux. Wild life is as docile as it can possibly be. I only nearly lost when the elves suddenly popup up not as merchants but as ambushers, riding a tiger and killed all my chickens and cats. I lost some dwarves, witnessed a tantrum train, and received an immigrant wave shortly after the elves gave up chasing cows and went away.
I then checked the civs and the elves are at war with the dwarves. So at least that was normal.
(one thing about elves, they never asked for tree cut limits in this version, in the ~5 games I played)
2 more years passed without any invasion or even a single hostile creature.
Actually, I just got my first goblin snatcher writing this sentence.
In an earlier game, a similar embark cave-in drained a very tall magma pipe and exposed the pit through it, as high as 10 levels below surface.
