Thanks for the kind words, Merker. I'm glad people are enjoying them.
You'll unfortunately have to wait a long while for the surface magma trap. That's a VERY long term goal, and requires me completely recovering the surface from the invaders to work in peace. You don't play with magma on the surface while you're getting sieged 3x a year until you've got significant defenses. Because, you understand, it's not just magma. Undead don't die to magma. It'll have to be an obsidian trap... Rediculously dwarfy and complex at that scale... particularly since the biome is freezing. Some magma will keep the water as... well... water, other magma will be there for obsidianization.
Toady may release the next version long before I get THAT particular mega-project done.
FurnaceClans is proceeding, for those curious, just not much that's film-worthy. The tree farm is about 1/2 dug out and there is SO much goddamned rock. The stairway to ice-heaven was building but it's one of those things that has to take place in between sieges and ambushes, but the stairs are built and the flooring's about halfway done. Having to occasionally clean out some undead from the entry because he dodged in the hole doesn't help.
Also, oddly, floating FB Extract doesn't flow down a hole when it's opened up underneath it if the hole never actually drains under 6/7. This is good, it means I won't have FB Extract in my tree farm.
Plans are being designed for a more effective surface access path, including a dwarven bathtub to remove surface contaminants. I haven't even started that dig yet, but I'll make sure you're around for it. I know dwarven bathing can be a sticking point for folks, but with an aquifer + DWR's it should be relatively simple. At least it looks that way on paper. I usually do it via gravity flow so this should be an experience.
Um, yeah, that about covers it... it's pretty quiet at FurnaceClans, actually. Most of the undead are dealt with (ignoring the one-off pathers that hang around at an edge) until the next ambush shows up... or when the humans siege me and won't path until the goblins ambush and they meet each other and resulting raised carnage cuts me off from the surface for two years waiting for them to clean themselves out... jackasses. We're just running a LOT of rock around right now... in anticipation of running a LOT of trees around in a year or two... or three or four depending on how fast these poor guys can go.
