I'm going to melt down the two steel crossbows I just got off the humans and start forging/melting corkscrews to turn the two bows into complete sets of steel armor for thirty dwarves. Such arcane works of forging would be of interest to any anthropologist, and one could have much fun musing how they acomplish this feat.
That's hilariously broken.
I thought you were saying to create a fort on an embark with no decent metals or flux. I could do a metal-free fort, but I wouldn't expect them to survive any real challenges, unless they found obsidian to make some macuahuitls (aka stone short swords) and wore the maximum amount of leather and cloth armor.
Very broken, but only reason I'm using it in my current fort is I picked 'metals' so I wouldn't be starved for metal weapons or armor, and wound up with silver as my only useful metal.
I see access to a freeze/thaw cycle, aquifer related plumbing, unwelcome guests, and a limited resources forcing arcane dwarven rituals as an entertaining mix of things to give you many different directions to take things, also putting early but (hopefully) light pressure on your dwarves.
If you are new to aquifers, I'd recommend you bring a rock or two for making pumps, and pick a site that has multiple biomes. In my experience, aquifers don't usually extend beyond their own biome, so if you give up digging through the aquifer you can look for the path around it.
I'm hoping to hear suggestions from others, what I see as entertaining may not apply to everyone else.
