DF General Discussion / Re: Are the underground caverns affected by surroundings? (Evil, Good, Savage)

I don't think A_Curious_Cat's statements are correct.
Note that my knowledge is based the pre Premium situation, so things might have changed, but I suspect they haven't.
Each cavern layer has its own biome, but Evilness/Savagery isn't part of a biome but applied on top of it, so if it includes an Evil creature it only shows up in the local biome if the governing world tile is Evil, but won't show up if it's Evil but the critter doesn't belong to the biome. However, there aren't that many things that are labelled as Good/Evil/Savage that can be included in the cavern biomes, but there are some. I believe there are restrictions to Blood Thorn and I believe Evil Eyes are tagged as Evil.
Savagery likewise carries through to the caverns, so you can have two visiting groups of critters in the caverns at the same time instead of the normal single one.
Thus, I would suggest modded critters for subterranean biomes would differ based on Evilness and Savagery if you were to try.
It can also be noted that Evil behaves differently depending on whether the Evil is a result of spreading from e.g. a Tower as opposed to if it was part of world generation. One thing that differs is that vegetation death always is 0 or 100% in spreading Evil, while world gen Evil can have any percentage in the 0-100% range. I don't know if there are other differences between "inherent" and "spreading" Evil.
