Hi!
the craftsdwarf stuff is currently strange in a way that a lot of things are created from iron. also got an iron artifact without iron in the grabbed materials ;) still, pretty weird :D
I got exactly the same artifact story as well for my third artifact. At least, it was worth more than 4,800 :) :) :) It was the first child born in the fortress who had been four years old at the time, and he really gave me a scare as he sat in his workshop not starting the collection. He demanded body parts, leather, and cut gems. I had bins of leather (not even a leatherworkshop in the fortress, so all unharmed from trading and a few butcherings), and I also had bones and what not. I figured I had used up all cut gems so I hurriedly made a raw green glass job at the glass furnace (I should have simply checked my stockpiles first - there was still glass left (^_^;; ), but just as the job was about to be done by a dwarf, the youngster was on the move.
The solution to the riddle - he still insisted on turtle shell and had simply waited for one of my dwarves to clean one of those critters. I supposed the iron that came out of nothing (would have been available if he had wanted it, though) is kind of an apology for the scare he gave me.
Ah, and despite it being an iron artifact, he did turn into a legendary bone carver (skill-wise, he is still a red, now blinking, child).
In other news, I had a wild goat enter my wall-off surface section of the fortress (the only entrance being the road for the trade depot, which is not trapped yet). That wild goat had probably come to complain about the weapon traps outside, because it was seriously injured with several red entries, even for organs. I hoped it would drop dead on its own accord as I didn't want to get into the potential trouble of the military yet, but it toughed it out. To make matters worse, I was currently trading with the elves, so no help from the merchant guard either.
In the end, the goat left and instead went for a re-match with the weapon traps. And the weapon traps stayed victorious, and having scored the second victory on the goat followed the call of "Finish Him!".
