The magma forges have been fired up. Only 14 dwarves died from madness, either starving to death or going berserk and being put down. Also, while channeling the 3-z level tall corridor around the magma forges, there was a cave in that managed to collapse part of the floor into the magma plumbing below. All that remains of the unfortunate miner is the copper pick.
Also, 3 other miners got turned into magma vapor while breaching the 5 holes into the volcano. They were given basalt memorial slabs behind an alunite door in the magma plumbing for their sacrifice.
They have a tavern now so they can better drink their misery away. I tried giving the miserable ones some crafting work to get legendary skills, but even after realizing their dream, they are still down in the dumps. On a somewhat related note, I just found out Cavy Boars are not actual boars and butchering them produces no meat or much of anything useful, only a skull. So they along with all the rabbits are up on the chopping block to save the pasture greenery. With a name like "Boar" I was fooled. 50 of the guinnea pigs have to go now. Hmmm... Let's see if I can pasture them with the grizzly bear I just got from the elven caravan. What could go wrong?
With all the trade up until the magma forges got fired up, there is a backlog of 800+ metal bars for the metalsmiths to work with.
