I just embarked on one of my "normal" runs (meaning not on a glacier, or in a terrifying biome, or whatever), and the first announcement I get is that I've discovered a lair! So I go over and look at the lair, and inside is a Voracious Cave Crawler. Well I steel myself up for a good fight, draft everyone into a squad with no equipment at all and all 7 dwarves charge into the lair to try and wrestle this thing to death. And the thing is, that's exactly what they did... it managed to make one of the recruits nauseous, but we chased it around the map for a day or two and then someone tackled it and someone else kicked it in the head or something. And now life is back to normal; nothing in the lair was worth taking, so I'm just ignoring that pit in the ground and digging into a mountain wall as planned. No one even got any points in fighter, striker or wrestler, so that was all pointless.
In other news, my glacier fort just got flooded when miners somehow managed to flood the upper level of the fort while hitting wet stone to irrigate farms in the lower section... I dunno, maybe ice melted and upped the water pressure or something, but nothing's going on with the surface. Too bad too, I was rationing wood, and had made my way into the rock layer, things were going pretty smoothly too...
