I am in the process of constructing a MASSIVE pyramid. In total it is going to be around 25 z-levels tall, mostly aboveground but some underground as well. I am a little over halfway done with it, and it already contains about 12,000 marble blocks. As you can imagine, I have some serious interior space to work with.
Unfortunately, I don't know what to do with all that space. Of course there will be lavish living quarters, tombs, and stockpiles of booze, but that'll only take up a fraction of the space. I intend to release this construction for exploration in adventure mode, and I want it to be filled with amazing things. I'm looking for suggestions from you guys.
Restrictions:
Due to a bug in converting to a newer version, I have no trade. I am limited to the materials I have on hand. This same bug prevents immigration, so I am stuck with only 27 dwarves.
I have no water, no magma, and no anvil.
The pyramid has a staircase going up through the center. I'd rather not deal with making constructions that involve multiple z-levels, unless they're really cool. It has taken me so long to build all these floors that I might cry if I had to tear them down.
I don't want to deal with traps in adventure mode.
I have plenty of wood, booze, and food. It's a desert map but there are lots of cacti and plants. There is loads of marble, magnetite, flint, microcline, and mica. There is some orthoclase and malachite. I have a few gems, all chrysocolla so far.
Bring on the suggestions! I can't guarantee that I'll put all of them in, of course, but I'll include as many as possible so that you can all explore your own ideas in my pyramid.
