Heh. I have but one word:
KAbOOM!
A dragon appeared on my map, and promptly made a beeline for the trade depot. The elven traders screamed in agony as he roasted them alive (heh heh heh); unfortunately, my broker ignored the 'get the hell inside, NOW!' order and got fried too.
He's a lot tougher than those pansy elves, though. After he and the wardogs and some guards finished beating the dragon to death (yikes?), he swung his pick over his shoulder and casually strolled into the fortress... still burning. What's a little fire to a dwarf, right?
Then he decided he was thirsty, and headed to the booze stockpile.
What makes matters worse is that, in addition to the lousy temperament of dwarves who have just seen all their booze go up in flames, several of the barrels (of all things) were masterpieces. My carpenter threw a tantrum, and hurled a cat down the main hallway, where it splattered on the wall. The cat belonged to my mason, who promptly retreated into melancholy.
And of course, the burning booze didn't stop dwarves from trying to get to the rest of the stockpile (what was left of it), then heading on to other tasks... while on fire!
Soon, my wood stockpile was merrily blazing, my charcoal bins were sending clouds of smoke rolling through the workshop area, and my beds had turned into smoldering piles of ash.
I lost 26 dwarves before I abandoned. Sheesh.
