Well, my only fort I've been playing at the moment, is a fort where I struck adamantine and into the glowing pit, I sealed it just in time, a dwarf caught inside, a red demon came out and killed him, I was kinda annoyed but I knew that was the price to pay for adamantine, but just then,to Spirits of Fire appeared inside the pit area, and they set everything ablaze and killed all the people that were in the pit when I struck it, and it even killed the demon that just moments ago killed my dwarf, so I felt satisfied but then, the waiting began, I used the adamantine around the glowing pit to make weapons, armor, and stuff because I planned on killing the demons inside, and seeing if there was anything worth while, which there wasn't, but it made a neat room for my dungeon master.
But regardless, eventually I had some recruits and an axe dwarf with adamantine armor and weapons, ready to fight demons, honestly, I didn't think there was anymore than two of them, and I heard they were pretty badass but I figured if I used adamantine armor and weapons it would kinda even it out, also, the axedwarf was a woman with a child, I know I'm a total dick because there's no way he will survive, well, I recorded the entire thing, I could put it up here if anyone cares, but pretty much, all three of them get screwed and killed, the baby too, because not only was there 2 Fire Spirits, there were like 8 more Fire Spirits appearing after I unblocked the hole in the pit, so I'm like "WELL, TIME TO SUICIDE" and I just like, put all these peasants in one big group and activate them, sending them in the Fire Spirits' direction, and I had also put my two legendary miners into recruit mode, cause in the past I found that they work super awesomely, and now that I think about it, I should have sent them in instead of the other dudes, regardless, somehow they all died, I couldn't really make out how, and I lost like 20 or so dwarves, but that was only the beginning, guys went outta control, killing each other, killing pets, breaking stuff, it was chaos, I did what anyone would have done. I made coffins, as many as possible, while the fortress was going insane, I ordered the dwarves that would work to make coffins.
To dig out the one level of the pit I struck into, and replace it with a more squarish area around the engravings, the engravings were creepy, stuff like "The elves are withering away" or "The human is being tortured" or some kinda funny one like "The dwarves are on the ground in fetal position." and I turned it into their burial site, I put up every coffin, now like I said, there was a waiting period, and I ended up with like over 100 dwarves at the point where I struck the pit, and I lost 20 give or take a few, now, as I was making this burial site, people were dying left or right, just ment more coffins for me, when the dwarves stopped killing each other or suiciding, there was like 6 dwarves left, 3 were injured, one of them was a gem cutter that did most of the work concerning the coffins, my fortress would have died had he not stayed alive long enough for me to get migrants, I couldn't believe it, it actually said people decided to come there even though it could be their tomb, and I got some soldiers which was nice.
I finally finished the burial site, the total body count of dwarves, children and named animals was over 150, all in the three levels of the glowing pit area. The fortress started growing again, and I turned that room into the jail/Dungeon Master's dungeon, his tomb is made of raw adamantine because I totally just like, want the fortress to die so I can go to it in Adventurer mode, maybe find my adamantine weapons and armor. Nice fortress though, it survived like, 3 goblin ambushes, I say, Cage traps are magnificent, But they do not work on them Spirits of Fire.
