Given that my mine is currently overrun with a variety of creatures and is imperfectly defended, I have been working on the higher reaches of the space, having protected myself by breaking the access via the construction bridge from below. My current goal is to close in the sky-high view panorama window, thereby sealing the mine from unintended external access. However, fascinated as I was by the colours of the setting sun, I waited far too long to vacate the recently-installed construction scaffold on the outside window. Before I knew it, it was too dark to make my way off the perilous structure and back to the security of my nearby mining hut. I was able to create gaps in the scaffold at either end (it was still attached to the sheer cliff face), and resolved myself to wait out the rising of the sun.
That I am still here to tell this tale the next morning is the shortened conclusion to the experience. However, the cold from the high altitude (snow is prevalent), the grunts and cries of nearby monsters, the darkness of the night, the onset of drowsiness (normally, I pass the night by sleeping), and my vertigo-fueled apprehension of falling made for a very traumatic ordeal.
