...we could create some sort of oceanside embark, create a concrete fortress in the ocean, and then sail it into the ocean, to where there are resources that you cannot reach from land, and we could set up a dwarven "oil rig" that sails into position, "drills" into the crust, sets up oceanic mining expeditions, loads up on ores and magma, then pulls up anchor, and sets sail once again in search of new material wealth to plunder from the briney deep.
Nice idea. Though, if we have dwarven ships of stone, steel, and cannons, we'd also have to have
pirates! Dorf pirates might find it preferable to sink ships, rather than fight on deck. Then they'd scoop up any cargo that floats on water and retrieve the
treasure heavy valuables from the wreckage. Then again, I think some dorf pirates might opt to raise a bunch of
pet sea monsters to do the dirty work.
On the subject of grasses on evil biomes:
I embarked in an evil area and a lot of the ground is covered in, um, eyeballs on stalks. Will this actually work for animal feed or will I have to break a cavern?
At the moment, grazing animals will eat staring eyeball and wormy tendril grass as if it were normal with no ill effects. I'm hoping this will change in the future, but at the moment it's just cosmetic.
Perhaps grazing animals that eat those should make the milk and cheese taste funny?
Urist McCheeselover: Yuck... Why does this cheese taste of onion? And why is it rubbery and tough like leather?
Urist McObservant: Well, I guess there are consequences to living off this cursed, forsaken place. Maybe it had something to do with all those eyeballs and worms the goats were eating?
Seriously, though, I hope it does not make grazing animals sick or dying. That'd really limit the options for animals on evil biomes. Instead, you could have milking give some other substance, which has much less food and material value. It makes sense, too, because what cows and goats eat does affect the flavor of milk. If a cow eats a sizable quantity of wild onions, you can
taste it.
