Finally got this done!
The Stock of the Devil (full deconstruction)
A human, an elf, and a dwarf walk into a bar. The dwarf says, "Hey, you two ever 'ear o' tha' fortress, Kikrostbisek, up in the mountains there, wha' with the disappearin' an' such?"
The elf bespake, "Yea, that I have, O stout friend of mine! I have overheard strange rumors wherein the inhabitants thereof did verily anger an anciant god of the very volcano they setteled on. This, I eavesdropped, resulted in their rather immediate and unfortunate being set on fire. What do you think old chap?"
The human said, "I heard that they were under siege from goblins for so long, that they went crazy and jumoed into the volcano!"
The dwarf interjected, "Yer both wrong! Wha' really happened was tha' they were too greedy for their own good, and dug straigh' for the heart o' the mountain, and unleashed a terrible evil contained within."
The human said, "I've also heard about a vault that they hid somewhere in the volcano."
The elf did reply, "Yes, the so-called "Stock of the Devil", eh wot."
The dwarf drank, "*gulp* Yeah. I 'eard tha' they rose up a second magma pipe to contain it in. Makes me wonder wha's indide o' tha' thing. *hic*"
Save here:

I unfortunately do not have any screenshots, but just think of a magma pipe with a vault in it. It's the only fort in the world, so it should be easy to find.
