"Day 6 - My first mistake was to make assumptions on the matter of my rescue. My section mistake was to make assumptions on the safety of the mine. My third mistake was to act on both those assumptions in going outside of my safe haven. My best estimate is that I have left the workshop where I was secured about two days ago in search of aid, and I have found only danger. I approached the old living quarters but curiously, could find no signs of life. Whatsoever. I returned in what I thought was the direction from which I came but found myself in an unfamiliar locale. Confused, but focused, I attempted to make my way home, but found myself threatened by some species of feral creatures, which seems to have made this old mine its home. Although the specimen bore significant interest to me I chose to retreat, only to be outmanoeuvred and outnumbered by the beasts. I turned and ran injuring my ankle in the process, which I believe now is most likely a sprain, rather than a fracture. For some time I cowered and fled in the dark, but a few hours ago I discovered a door leading to a smaller disused part of the mine, the key for which I still have in my pocket. Within that area I discovered this store room, and I think it should keep me safe for some time. This place is a maze. My lesson learnt: I will not venture out again until I am certain the area is safe."
