Well, in my most recent fortress, (my first actually successful fortress, complete with noble genocide) I had recently burst through to HFS. The fort had been going for about fifteen years, and I was getting bored. I had essentially dug out the vast majority of the bottom z-level, and had locked my 5xlegendary engraver (last of the original 7) in the resulting cavern. He was set to trigger the mountain-collapsing lever the moment the military got slaughtered, which they did.
Next, I set him up to engrave the massive chamber, one square at a time, so I could actually look at them before he died.
Several thousand masterwork engravings later, he arrives at the last square in the chamber, and sets to work.
Now, this last dwarf was married to one of the crossbow dwarves.
I'm not on my usual DF computer right now, and I can't check legends, so I'm going to paraphrase what the engraving said.
"This is a masterful engraving by Cog *cannot remember title* of Urist *cannot remember title* and *head of the wave of demons*. The dwarf is laughing. The demon is crying. This relates to the striking down of the *demon* by Urist in the midspring of 79."
With his dying breaths, my last remaining dwarf had carved an image of his wife shooting the head of a demonic horde in the face at point blank range.
By a bizarre coincidence, it was at that exact point in time where one of the other guys on my floor started practicing his bagpipes. It was glorious.
