So... my level 10 metalsmith (immigrant) and resident Bookkeeper becomes possessed. As he just chills in the meeting hall doing nothing I start getting a little worried. I have a Forge built, but if he wants a bloody magma forge he'd better forget about it now. so after a couple weeks I take a look around I notice that my lazy dwarfs suspended construction on my forge and that I did not in fact have one. I happily make it work again to make sure McDwarf here doesn't go insane and rip the eyeballs out of the nearest dwarf to him in this meeting hall. As soon as its done he runs off happy as can be to claim the workshop... And then starts demanding bars. Which I realize I have none of because I have been refining coke to make sure my forges never stop running once they are up and going. So now i'm on a frantic mission to refine as many various metals as possible, because as stated before, I feel my little dwarfs need eyeballs. If only to continue producing coke for me. I go through this crazy refining project, and finally he sees what he needs! sweet victory. He will live, no exp of course but then again the lack of risk to my dwarfs eyeballs is worth it.
Until he finishes the project. Vushkikrost. An Iron Barrel. This is an iron barrel. All craftdwarfship is of the highest quality. It is encircled with bands of iron. Its also worth 24000 Dorfbucks. But i'm seriously considering killing this little guy now. I have no desire to ever see his face again. It's like he was drinking some rum, said "Hey... we never did finish that forge..." gets possessed and throws my entire dwarf workforce into chaos to satisfy his sick desire to make a barrel. I have hundreds of barrels. None made of iron of course. Because you know, that's pointless.
So what would you do to this little dwarven guy?
