So there won't be a resolution to the caravan crisis and punishment for that annoying kid? This is disappointing, even after priest left, Virtue should write a short summary of how the angry caravanners were dealt with. Those designs are very ambitious. Personally I'd settle for a well with clean water, trash compactor, more traps at the gate and at the entrance to the caverns. After that a 4-pump cyclic mist generator / shower (just put social zones where the water jumps, and ponies will also train
drowning swimming (it is safe, I tested the design on Dwarven children, and none of them were harmed)). Power it by a few windmills (if you have wind), and also link a quern. It took years to complete houses, and this place just doesn't have the pony power to complete some of the more complex designs.
Danger room is quite a liability, just as Jaxler said. I used some pet-impassable doors with mine, and 10+ animals were still killed. Kids are even worse, and since this fort is about being nice and protecting pony life, that danger room will have to be dismantled after the first accident, and Stiletto will have a guilt trip from proposing it. Jaxler would be even more pissed off at that alicorn for killing ponies. It can only get uglier from there.
If I were to discourage You from it in ponysona, I'd make a speech about being from a fort where something like that was tested, and eventually abandoned:
"Oh, it was very effective and a week in that room did more to the soldiers than a month of sparring ad demonstrations, but it proved just too dangerous. Soldiers needed very thick layers of armour and cloth just to prevent injuries. This made them tire quickly, and some even passed out from exhaustion while poked by the spears. But that's not all of it. Cats and other animals occasionally sneaked in there despite our efforts to keep them out, and were injured or killed. Once a civilian went inside to take out a dead cat, but got stabbed, and ended up in the hospital. Despite all this, our leader decided to continue using that room, because we were at war and needed trained soldiers badly. Eventually the inevitable happened, and a tragedy struck. A foal went into that room in spite of all the warnings, and her head was impaled on a spear. It was little consolation, that her death was instant. After that the spears were finally dismantled, mechanisms used for other purposes, and the room closed for good. Some things are just not worth the price. Are you sure you want to risk this, if the whole point is to protect pony life?"
Magma waterfall just screams
magma mist and
disaster, and it would require a really big pump stack, and patching up that pump stack through the caverns. It also means using large amounts of green glass for magma pumps (unless you want to be stupid like me, and waste iron for corkscrews and nickel for pipe sections). So far I completed a 20 or so pump mist generator powered by 3 water reactors, and a wall around a 4x4 embark with 8 dodge-me traps, but was unable to get magma to the surface before FPS death. Magma could also mean magma smelters, furnaces and forges, but I like the added challenge of not using them in this fort. It is also somewhat um.. anti-thematic (?) for ponies to have magma technology. Magma and underground fortresses and overly complex mechanical contraptions are more fitting for Dwarves than ponies. Just saying.
A lecture by Flux about steel carbon content (the more carbon, the more elastic and less brittle the steel is), and how charcoal is better than coke for making steel (because coal contains some sulphur, and sulphur makes steel brittle), would be nice. Maybe when you'll teach Granite about smelting or Stiletto visits you again in the smelter. Tough I'd rather start with something simpler, like smelting copper. There is no reason not to make a pony fort thread educational
If I wanted to be malicious I could probably come up with something about hamsters, vermin and cats.
