I was looking around a few embarks to see if I could find some rather extreme generations and came across this pair of mountains with a volcano tube going straight down the middle so I wanted to share it with everyone! I've included the empty world file (no forts yet) as well as some screenshots of where the embark is! The location features no above-ground water but does have a sunken lava tube and sparse tree cover in the untamed wilds of a savanna. Elves, Humans, and Goblins are within a short distance. The year is 125 and it appears that necromancers have risen in parts of the world.
The world size is "small" and features custom generation to encourage volcano formation. There are also a great number of beasts and creatures in the world still, so do be careful out there dwarves!
