Tried out an evil embark for a change. Volcano on the border of two (evil) biomes. Everything peaceful at the start, so i dug into the nearest wall and ordered everything brought inside. By late spring, an accursed gloom crept over the landscape, so i battened down the hatches and observed what it did. A kitten husk and two hen husks. Ah well, i had brought two kittens and three hens, no big loss. Forbade everything outside and ordered the entry walled off. Which happened before the kittyhusk made its way inside, but of course an idiot miner had to run outside before the wall was closed. Since there was no new gloom coming, i eventually got him inside after all. Breached the volcano from somewhere down the side (to avoid going outside for the purpose, the gloom happily crept all over the mountain whenever it came) by first hollowing out a basin below, then carving a fortification, smelted the cassiterite i had brought and combined with local bismuth and copper for unrottalbe 'clothing', got a dozen chicks to hatch and...
well, that was it. Nothing interesting happened, all migrants were huskified or killed, the caravans got scattered. A pair of husk has been pushing each other around for two years now. Four caravan guards rose as un-memorisable ghosts but the dwarfs are still happy about their legendary dining room. It's just boring.
Interestingly, the liaisons kept hanging around until they, too, got huskified and then 'left unhappily'. So at least we have an insight into the mental state of husks - they're not happy creatures. And they promptly wandered off the map, presumably to report back to the mountainhome:
"GRRAARGH BLARGLE WWWAAAUGH!! RNNMF!"
"Why yes, my good dwarf (?), the weather has been dreadful down in the mines, but at least this year's crop of children is coming along nicely. Another slice?"
"WRRRNBLBLHOWCANYOUBESOUNCARINGABOUTYOUROWNOFFSPRING?!?! THIS MAKES ME ANGRY! ANGRIER! WHATEVER! HUSK SMASH!!"[proceeds to eat the mountainhome PR flunky]
