Hey there, I just got into dwarf fortress and I've never encountered magma before. To that end, I decided to rectify that, so I used the reveal hack to find me some nice magma only to find that the only magma on my map was a few levels above the great magma sea.
So I've decided to embark on a silly project to build an artificial volcano by basically pumping magma from the sea, up to a holding cistern on top of my mountain, ready to be unleashed upon any poor fools at a moment's notice. And also get some damn magma forges up so I don't have to use coal.
What's troubling me is that there are several extensive cave systems on the way down and little way around them. If I want to get any meaningful size of industry done, I need to go through those caverns.
Unfortunately, I don't know how to go about it. I've found a couple of birdmen tribes down there, which I think I can kill easily, but not much else. Furthermore, I don't quite know how to go about. At first I was thinking of just burrowing my way in, walling that section of the cavern off, and working in the space that I created, but I dunno how well that would work.
Any tips you could give a newbie like me what to do? I was reading up on the great magma piston, but I think that's outside my capacity, and I wanted to make a constantly flowing river of magma, while the magma piston only works once to get one massive reservoir of magma.
TL;DR: I want the delicious magma, but only magma I can find is from the magma sea. There are several caverns in the way filled with Urist knows what and I have no idea how to get a magma pump going, nevermind in a cavern. So, what the hell should I do?
