Arm the magma hallway.... standby.... They'll path in to the fort eventually.
Anyway, it's not fun to burn them down to nothing in some god-forsaken hole. They should instead go for the lever on the upper level of my temple/dining room. Then step back, get dropped on a trap, then get hit with a dust cloud. With every single dwarf watching. This way the children probably won't care about anything anymore way before adulthood.
Also, the water has now started doing things that I can't understand. The summer has arrived and water has started evaporating; my legendaries managed to pump the stuff from the meeting area, so I sealed the apparent leak. Then both misplaced wells started to leak again. To top that up, I made some mistakes while constructing emergency drain, and now water level in the dining room roughly equals that of it, meaning 7/7 most of the time. I no longer understand how this stuff works, so I'll just blast that brook with another magma cannon and wait for the drain to do the job.
The nobles are now living in a burrow, supported by several migrants. They still have to drink brook water and hunt for vermin, though. I'll use them to build the outer part of the cannon, well, if they won't die of goblinite overdose before. I also learned that some of that goblinite is actually useful, and that it could provide my run-out-with-no-job idiots with a prolonged life and some kills.
Also, a siege led by local goblin leaders happened a while ago. It was fun. They entered the northern caravan passage only to get butchered by traps I set up in order to butcher any ambushers. A mighty, well armored elf axelord stepped into one of them and got both of his eyes poked out. I thought it'd be fun if he escaped like this, but since his squad was perfectly fine, he moved on instead, only to get slashed apart by several *large, serrated green glass discs*. Then others came and left on traps half of their squads. Then I closed the blast door without looking who's left with the gobs. I channeled out the tiles covering its area, so naturally, there shouldn't have been anyone there. But it turned out that dwarven idiots never learn. Despite having three tiles of outside light in their way, they somehow managed to get themselves in a straight, narrow, and empty tunnel. However, most of the idiots were now ultra-mighty and superdwarvenly tough, so it was different.
The three predatory things I chained in a row right after the trap array had lots of trouble coming. One of the giant lions got killed almost instantly, the second lasted two seconds more, and there in the center was an Alligator. This one jumped around, easily dodging the two wrestlers and a speargob for a time enough for me to gather the unarmed idiots into some sort of idiotic force. He alone lasted seven seconds, but the force was already dense enough by then. And so they charged. Ten superdwarvenly tough, perfectly agile and ultra-mighty
idiots. Some of the gobs were thrown into the entrance and got damaged on impact, some got their clothes wrestled off and were beaten with them to death.
Two sizable ambusher squads remained alive, so I quickly armed the idiot force with random bits of goblinite that was scattered around and set them to wait in the tunnel... but all the remaining siegers run away. They got scared, they'd better get scared!
There was only one dead dwarf, and a hauler with lots of brown wounds, which healed almost right away. He also had a mangled hand, but since I have no beds for him to rest, he runs around carrying stuff just fine.
