I was making adjustments to the demon-clearing plans, when one of the resident dwarves offered to show me some more of the area. I was unaware that there was more between us and the demons than just the hallway I was improvising, but he assured me there was.
I was taken down into a small microcline chamber, where a large stone slab was apparently sitting over a direct hole into the demon chamber. The croaking from the frog demons resonated in the small chamber, and the foul gurgling and grunting noises were beginning to get to me.
The dwarf asked me if I wanted to take a look, and before I could ask him what he meant he activated the mechanisms that raised the stone slab!
I thought I was going to die in that damned room, and that my last thought would be about what my blood looked like on microcline, but aside from a burst of excited croaking (which had now grown almost deafening, due to the open space), nothing happened.
I brought myself to look down into the hole, and far below I could see the gleaming eyes and glistening skin of a multitude of frog demons, all belching their strange language and looking back up at me from their muddied pit.
I turned away from the pit, as those eyes were sending chills down my spine and into my toes. The malignant thoughts of torture behind those bulbous eyes were so strong you could almost taste them. Simply seeing them required no effort on my part.
But along with the chills, I was warmed by a spark of an idea. The chamber was too steep and too high for the frog demons to clamber out of, and this made the hallway I had set up rather useless. Instead, a new idea entered my mind... If you can't bring the demons to the hallway, bring the hallway to the demons.
I started drawing up a few sketchy plans and making measurements, and things were starting to line up. With careful planning, the rock surrounding the microcline chamber could be dropped down, through the empty mining cavern beneath, and finally into the domain of the frog demons.
With my previous experience in dealing with adamantine pits, I recalled that they most often formed in layers stacked on top of each other, until finally opening up into the demonic prison itself. With the cave-in I was planning, the layers should accordion into themselves, collapsing into a mass of frog flesh and rubble.
I was getting over-excited, of course. There would inevitably be some survivors from the fall, but with the inability of the frog demons to crawl up steep walls, the marksdwarves under my command should be able to pick them off from safe platforms above the rubble.
I immediately ordered the proper digging plans into action, but "immediately" apparently means something different around here. I'll be lucky if they even start digging out the area by end of autumn.
