Dear Possessed Glassmaker.
You want a glass workshop, alrighty then, I don't have sand on site but have 6 magma smelters, I can convert one to a glassworks, and I think the traders left some sand last visit. Oh you don't like magma? Here have a standard glassworks in the old adamantine vein. Ok cool, ya claimed it.
You want raw green glass.... Yer in a glassworks with sand available...but whatever, I'll have somebody make you a chunk of raw glass at the converted smelter. No worries.
There ya go, glad you liked it. And now you want logs...there's about 50 logs up by the carpenter's shop...hmm...maybe I'm reading yer demands wrong. You also want cloth? Our primary export is rope reed crafts, we have plenty of cloth. We're producing it faster than we can process it, there's something like 200 units of excess cloth up by the crafts workshop. Thread too.
...Well maybe you want silk cloth. That's a bit of a pain, but I can get that. I'll just send some weavers into the cavern under guard... there you go 5 units of silk cloth and 3 units of unprocessed silk thread, just in case. Still no?
..Well maybe some wool. Somebody has a pet sheep someplace...there you go, one unit of sheep wool cloth. Still no?
What the fuck do you want with me? I have supplied all you asked! All you took was the glass! You want wood? Theres tons of wood! You want Any kind of cloth under the sun? The stockpiles are overflowing!
Here have a few guards...and a locked door. And your own personal tomb that is suspiciously shaped like one of the premade generic gravesites given to idiots. You are a glassmaker, on a map with no sand, with a possessed mood. You don't deserve the effort I put out to satisfy yer needs. Have a nice life, what's left of it.
Sincerely,
The Administration
(Seriously, no idea what this guy wants. The only thing not mentioned is leather, which again, the stockpiles are overflowing with. It's definitely not a resource shortage.)
