Oho wow this thread is awesome!!
But anyway. My current fort, slaughterrocks, is my longest-surviving fort yet, but it has
sure had a very rocky life... We have had
twenty-four forgotten beasts attack us, at current count.
I haven't really had a decent military at any time, I've just had a few heroes here and there, but we've always managed to deal with the beasts somehow, usually by strength of numbers.
Anyway, one time some horrible creature was seen wandering around the upper cavern layer.
I was ready to despatch my dwarves to deal with it... But it just sat there under a z-level or two of water.
Avuz Ebtig Godumavuz, an enormous dimetrodon with lidless eyes. Large mandibles. A gaunt appearance. Blocky, overlapping mauve taupe scales and DEADLY DUST!! In my freaking main water source!! Oh well, it didn't seem to be doing any harm, so I kinda forgot about it.
Then, a while later,
another monster shows up, and goes to chill out with Avuz.
Now, that was just
too much! I send my large, mostly inexperienced military down there to kill 'em!
...It was the most horrifying slaughter I've ever seen.
The two beasts just
burst out of the water as my dwarves reached the shore, spraying poisonous steam, and lunged at them... Actually they were like a team, the big quadreped made of amber, named Nagnod Swamholes the Deadly Eels, was tanking, getting stuck into my dwarves and tearing them apart toe-to-toe, while Avuz was sort of... Flying around the upper part of the cavern, propelled by his dust or something.
EVERYONE DIED. Luckily I saved before I sent 'em on that mission.
One of the only times I savescummed.
Anyway, bla bla bla, part two. Those two beasts lived in my water source(Which became the source for my new well) for ages, feeding (I assume) on the two stupid dwarves who fell down while working on the well.
They even ignored another forgotten beast, who flew straight past them and up the well...
Then, a few years later, some clumsy dwarf drops a lump of stone or something down there, and wakes up Avuz who starts killing people.
Avuz died, but it cost me my only remaining decent warriors...
Just my fort's luck!
