Oh god, raining goblin blood? A dream that came true? No dwarf would ever be grouchy of being caught in the rain anymore.
I kinda want to make a playable fire-based civ, but also a invader-only demon civ that uses actual vanilla DF demons. Obviously impossible to do both. ^^
I don't know if it's impossible because of the time, because of the work (modding things is an alien thing out of reach for me to understand) or because it would be a incompatible lore.
If it's about the lore, and what you really want is doing an inorganic civ, would be a nice idea of a elemental-civ with tons of castes (fire elemental, water elemental, air, fog,rock etc.) and they could have many excuses to be there
(i am repeating some things here, but it's just to make sure i can be understood, so much time without writing in English)
Good: "The nature is getting alive"
"Their original plane is dying, ours is the best option"
"good gods created them so balance could be restored"
Savage: "The elements are alive! And they are fighting back"
"a god of [anything related to nature] sphere brought the elementals so order could be restored"
Slavers: "The nature is alive! And it swear REVENGE"
"wizards are growing elementals, and mindless slaves are constructing weird ~natural~ buildings, may the gods save us"
"god X brought elemental so wars could be waged"
Evil: "The elements are alive! And they are ANGRY"
The play-style could be something like this (or something else you got in mind):
Could sacrifice two kinds of elementals [water and air] or just one in the right workshop [water elemental in a rune furnace or something] to make another one [fog? mist?]
Could lock a pair of them like animals so they can breed (
