My most recent death was rather depressing for me. Here we go:
For many fortresses I have waged war upon the fire imps. With my graphical tileset, their fiendish little yellow grins simply make them look even more smug about their obscenely pointless destructive power and hostility.
A group of imps had been circulating around the fortress entrance and were now skulking in a sort of alcove, and I decided that instead of hunting them with marksdwarves (as I feared the insuing brush fires), I would send my brand new novice mechanic/siege engine operator/siege engineer to go and place a cage trap nearby in the hope of snaring one of the bastards so that I could take glee in feasting upon their flesh and making their precious (but of course, burning) fat into soap.
Upon placing the trap, my engineer took a short cut over to the fortress in order to acquire the cage to set the trap.
However, as the engineer neared the top of the fortress entrance as his shortcut took him 1 Z level above, one of those black and red swines appeared behind him and promptly unleashed a hail of fire worthy of the pits of hell itself.
Panicking, I desperatley sent my recruits over to save him, and realising time was running out drafted some of the carpenters who were milling around by the wagon.
One recruit managed to arrive quickly enough and quickly savaged the imp, butchering the little bastard.
But, alas, the engineer that I had worked so hard to save, my brave little dwarf, lay unconcious, charred and dying. I saw far too many browns and far too many reds. Eyes, fingers, arms, most suffered from severe burns, if not removal. Possibly due to throat injuries, he began to suffocate. Iden Otameshtan died in the snow.
Using my taskmanager to close dwarf fortress and reloading the savegame, I waged eternal war on the imps. I will not rest until they have been exterminated in any way possible.
