Well, I'm pretty mad right now. Another Forgotten Beast appeared in the caverns. Nothing surprising or dangerous about that. I send my military to go kill it. It manages to strike down a fisher dwarf before they arrived, but that's not to surprising. However when they began fighting I noticed a problem. This creature would let out huge bursts of frozen extract, and when it did this everything (inculding itself) would be knocked around the cavern. I don;t mean a few feet either. They could be flung several yards by this blast. Since I spend spare tiem modding creatures, I quickly realized the Forgotten Beast had an [UNDIRECTED_DUST] attack. I'm shocked Toady actually put this in the game since it's so buggy. The physics involving dust is screwy, so for some reason it blows back everything it touches.
The fight quickly went south. The military commander charged at the beast. He was knocked back. He charged at it again, only to be knocked back once more. Only this time he was blown over a cliff and fell several z level, dying instantly upon impact. The beast had killed my favorite warrior without even touching him. My hammerlord was in the same blast, but he was crippled rather than killed. So this beast took out my two best warriors in addition to the last soldier of the second militia squad. All because it used a buggy physics attack the harmed itself. The rest of the military managed to slay it because it had also been seriously wounded by its own stupid dust.
EDIT: Ugh. Both my new milita commander and the hammer lord died from their injuries. These Dwarves have been training for years, and all of 3 of them were wielders of artifact weapons. That's a serious blow to my military's strength.
I don't know who I'm going to replace the captain with. Probably who ever manged to slay the beast. Aside from this, Townbrush is actually doing okay. The outpost liason (who somehow survived a goblin ambush and a repeating spike trap by himself) promoted us to a barony. He was bleeding heavily and missing a finger though, so I imagine it was an awkward meeting. Normally I make myself the baron, but I died so I made my former wife the baroness instead. She is the only one of the original seven that is still alive as well, so it is fitting. So far she has been easily pleased and all her mandates have been tolerable. Hopefully she won't have an unfortunate accident like the former mayor did.
Also continuing in the trend of pathetic replacements, the Captain of the Guard was torn apart by a horde of zombie lesser kraken. I'll have to wait for migrants to replace him, so nobody has any relevant skills whatsoever.
