She has made Baladegom Likotizkil, "Coilnature the Inky Intricacies" (say wut?). An artifact willow cage with a picture of oysters in willow, worth 2400 dorfbucks.
It is symbolic of how we will be catching all the huge savage animals of this savannah once I get off my lazy arse and order more cages and mechanisms to be made (quite busy prettifying the fortress...ooh, statues!), and also symbolic of how she detests oysters. Maybe she's expressing a wish to see all the oysters of the world stuffed into one tiny cage? Maybe she was inspired by seeing the fort's entire puppy population crammed into one as she was arriving? I doubt oysters would care much about being stuck in a cage, but hey, it's her artifact...
My magma forges are at the sea, 120 z-levels below my fortress's main levels.
Whenever a forgedwarf gets a mood, I'm not worried that he'll not find stuff, since my fortress is 30 years old and so far I haven't found an item type I don't have. - but I AM concerned about him dying of thirst because (although the bar stockpile is on the same level), all other items in the fortress are 120 tiles away - and if he has to go across that 5 times, and he was already thirsty - I've had some close calls.
That sounds like it takes a lot of walking to get any forgin' done. Have you considered pumping the magma up, instead of going after it?
(The dorfy solution to having to walk down a hundred-and-twenty flights of stairs is to build a massive iron pumpstack powered by windmills, obviously.)
Edit: I have ordered Baladegom constructed at the entrance to the dining hall/statue garden and will be cramming all the puppies of the fort into it instead of the measly alder cage they now reside in. Good thoughts ahoy.
