Currently waiting for a giant to massacre all of the local wildlife before he heads for one of my containment cells. Unlike a previous fort where I tied a puppy as bait, this time I’ve got a built artifact coffin (rock chrystal, iirc) surrounded by loaded cage traps.
For some reason my ridiculously open fort had a batch of miscreants hanging around near the edge of the map for over a year consisting of poets and bards and the like and worse elves, and a minotaur suddenly showed up. I moved out the military into the front since these are usually no big deal but he barged into the idiot convention on the edge of the map instead.
He killed a bunch of useless poets and elves and the like but one of the bards punched him to death. At least it broke up the loitering, whatever that was about. I assume they were up to no good. Military went back inside.
I've also been trying to set up a trap where instead of an actual trap hallway (have one of those already), there's an opening from the surface to the bottom cavern layer, and then another that involves a zig-zagging course through all the caverns on the way back up to the fort, so when the proper gates are open and closed, they path in. So far I haven't been able to tempt them in. The idea is just letting the FBs that have been there for years and the invaders duke it out. I don't want to deal with these webbers and gas spitters and so on.
