So. While plinking away at a FB of ice, for so long that every single bodypart of it was broken and riddled with bolts, I finally gave up trying and decided to send in the melee guys since crossbowers obviously weren't doing shit.
This thing had a deadly dust attack though, so I didn't really like the idea, but "luckily" the squad sent in was mainly composed of guys who fell victim to a poison gas FB attack earlier and had most of their skin removed during surgery. Advanced rot, and all that jazz.
Well anyway, there was trouble. First was that along the FB, a giant spider arrived. Just a normal cave critter so ehh. What's the worst that could happen?
Well, it's that the spider would decide to attack along the FB, making a beeline for the fort once the perimeter wall was torn down. And of course about a few moments later I found out that A) it's hard to fight a FB when it's accompanied by a webspitter and B) the deadly dust was the sort that makes you bleed to death in a few moments.
As luck would have it though, the militia captain of the squad did everyone a favor and bisected the FB a few seconds before they bursted into a shower of gore. The spider? It killed a miner. The last survivor of the squad engaged and killed the beast before it could kill anyone else, so for the time being, threat eliminated.
Except that a mason took the miners death pretty badly. So badly that they went to complain to the mayor. While tantruming. And the mayors pet pig arrived to the same room they were holding the meeting in.
In hindsight, giving a Civvie outfit(to combat deadly blood epidemics) along a personal weapon for everyone was a bad idea, considering how the mason chopped the pig to pieces. The mayor took it badly, went Unhappy, and the Mason was put in jail for 200 days.
Situation solved, right? There was also a tantruming jeweler who attacked a pet metroid and tried to kill a metalcrafter(who parried blows like a boss despite no military training) that got jailed but anyway.
A while later I get the announcement that the old mayors mandates are over. Reason why was simple. They had gone from Unhappy to Miserable and babbling insane in a matter of few weeks. Why? I have no god damn idea.
They were a good mayor too. Only wanted trifle pewter and beds. The new one wants at cabinets so far, but they got native gold and bolts down in the list too. At least it'd be some variety.
Oh and the mason? They died in prison. After the first few times dwarves brought them food and water, no one visited by the time they had 50 days to go. At least there were no cases of unhappiness resulting from the death of the old mayor and the mason.
But still, I'm down 4 seasoned and skilled military dorfs thanks to one fucking FB and it's hard to find replacements in a 20 years old fort. What with everyone having friends that'd miss them if they had a gruesome horrible death.
