The humans arrive to trade. I send some things off to the depot, including the goblin cages I'd like to clear out. Much interruption spam ensues, and my dwarves get some target practice while the human guards finish off the punctured goblins. The partially-drained cavern is stained with ribbons of blood, and scattered with body parts that are still too submerged to pick up. Somewhere in all of this I miss the caravan's departure (ehh, I'm good, I only really wanted to stockpile stuff in the depot anyway), and a dwarf goes into a mood and claims a magma forge for a weapon. After a couple of savescums, she finally makes the weapon I modded in and haven't really gotten around to testing. The last time I tried doing that, I didn't get the weapon after about a dozen tries and wondered if perhaps I'd cut the size restriction unecessarily fine. Clearly, Armok was pleased by my goblin execution strategy. After checking out the weapon's decorations, I save the game.
A couple of days later, I get the message: "Astesh Baletur, Miner, has been missing for a week." Okay, maybe it wasn't the goblin execution that pleased Armok. Damn, one of my founders too. I hadn't been digging above the magma sea and couldn't find a corpse in the stocks screen, so I saved again and then used DFHack to resurrect him so I could find out what happened. Turned out I'd forgotten to leave an escape route behind a pump I'd built, and since it was right at the edge of the safe zone formed by the action of some other pumps a tiny bit of magma had sloshed over the pump and incinerated poor Astesh before I had a chance to return to the work area for the next lot of building work or catch a 'Hunt Small Creature' job on the Units list. One force-quit later, and I moved on.
The next season rolled around, with the dwarven caravan absent due to crash issues. However, the goblins were on their usual schedule, and because I'd forgotten to close the front door (and also forgotten that I didn't need to open it to let the humans out, because I'd built an exit-only route) they caught a weaponsmith outside. With no-one else around, the weaponsmith was quickly killed, so I ordered the whole fortress except the miners and woodcutters out to avenge the fallen dwarf. Luckily, the proper military had a couple of members nearby, and the goblin squad was charged before the civilian mob could wade in with their bone crossbows. Despite several more ambush squads turning up and adding more targets, the goblin who'd bashed Sigun's head in was chopped up a piece at a time.
Amxu Amxustot's silver warhammer remains outside, next to his still-forbidden body and limbs. I may give it to Sigun's wife, and enroll her as a hammerdwarf. Amxu's bones will be turned into trophies, and his hands and head and mutilated corpse presented to the captive necromancer and be used for target practice for all eternity.
