Today is turning out to be a pretty fun day.
Currently building an obsidian factory, so I was a little distracted. Designated some trees to be cut down in a cavern I opened up, and got back to the water channels. First facepalm is when I start to dig out the last layer above the magma. Naturally, some idiot decides to channel the wrong bit of floor, and 2 of my legendary miners fall to their fiery demise.
Not that I minded too much, still got 5 legendary miners. At this point, some people got a little upset, because one of those who died turned out to be one of the original 7. Not great.
Anyway, after deciding to give up the channeling and get on with setting up levers and floodgates and so on, I notice a pink message. Oh? None of my dwarves recently went into strange moods. I go to the announcements, and it turns out a bloody GCS spawned somewhere in the caverns and has now ravaged 5 or so dwarves who were hauling wood from the cavern. Luckily, none of them particularly useful (ok, a legendary + 5 gem setter, but I never do anything with gems). I get my militia down there, and the spider is dead within 5 seconds or so.
Anyway, the aftermath is that someone goes insane, one dwarf suffocates a few steps from the hospital, and my legendary weaponsmith who singlehandedly forged every weapon my fortress possesses, decides to go on a tantrum, although luckily this doesn't cause any problems (it seems).
Also, I get my first fell mood. The dwarf that he grabs is some useless planter with almost no skills whatsoever, so that's fine. I'm hoping I get something reasonably nice, although my hopes aren't particularly high. He ends up making this:
Hooray.
