So, after I showed off Rimslaughters last year, I took a long break from DF. But lately I've been looking for ways to procrastinate (I'm taking the bar to become a lawyer in a few weeks... studying is boring!). I came up with an idea for a new fort, a twist on the Undergrotto massive-cavern idea: The Bore.
My plan is to drill down from the top of the fort to the very bottom of the magma sea, approximately level 104. I'll leave in a few stalactites and stalagmites, and I'm also going to add some other fun features, but mostly I want a giant empty cavern, save for the interior pillar and a long circular stairway for caravans. Right now, I am mining out stairs on each level, and eventually, I'll drop the ceiling, which will punch through all the empty levels and hopefully make my job a lot simpler.
This thing is going to be BIG.
It takes a long, long time to mine this out. However, one of the fun things about this fort is that I can basically leave it completely open to invasion, and the defenses (plus some military screen planning) make it pretty much impervious to assault. I have had to intentionally disable some of the traps, just so the later traps get to have a little fun. So far, nobody has made it past the third line of weapons traps in the back door:
So, that's pretty much the plan. I'm posting here at least in part to keep myself motivated, so let me know if you guys have any cool ideas for the hollowed-out section. I want to make some glass-domed areas, like little dwarven terrariums, as well as an artificial volcano that the trade walkway will pass directly through. I am also considering a giant iron bucket filled with magma, hanging from the ceiling on chains, which will drip down onto the glass-enclosed magma forges far below.
Work faster, furnace operators, or I'll open the roof.
And in case anyone is curious, here's a few of the stocks screen as they stand today.
I'm most proud of the third one - 1,571 mechanisms in use!
