Hi guys! I've got a pair of maps that I just have to share due to their extreme (and badly corrupted) nature. If anyone wants them, I can share the map files themselves, or the world generation.
I was attempting to make a nice cold, terrifying map, and manually tweaked the world gen text file past the limits DF would let me ingame. I now know why, as the maps it generated are all corrupted in one way or another. These two embarks were from the same world. The map-files linked are not wrong in any way, the maps look exactly as pictured.
The Fortress of RungsealA volcano reaches so far up into the sky that the top cavern sits well above ground level, bisecting the frozen brook. The cart sits (on level 182 of the map in the Archive) on the very edge of a near-perfect square of forest, directly south of the volcano.
But, to top it off-- in the lower left corner, an adamantine spire arcs up into the sky to the very top of the map, seven levels higher than where the cart embarks.
I thought this map would be nice for an extreme fortress, except I peeked around with dfhack and found a cube of Hell] sitting in the lower-right corner at the level of the second cavern. I don't really know what would happen if the second cavern was breached, but the open space reaches all the way to the glowing pit.
If you want the worldgen to embark on this map yourself, be prepared to wait a while (5-10) minutes to embark, and then another 10 minutes after unpausing as things fall all over the map.
The Fortress of ThinnedarmorsMuch more peaceful and absolutely perfect on top, but beneath the surface is a landscape too dangerous to even mine in. Semi-molten rock reaches up to the first cavern on a large percentage of the map, causing the caverns to entirely flood with lava, and killing FPS until they eventually fill.
While they're ridiculous maps, I was trying to make something much less extreme, flora-wise.
Edit: Hidden all of the spoilery stuff, and the worldgen is below! I unfortunately can't find the embark for Thinnedarmors, but Rungseal is below. The actual embark is one square to the left of the picture, so that the volcano is not in the corner.
