Diary appears to be written by a stranger lost in a strange land, possibly a human trapped in the Dark Aether.
Document Text:
Day 95: Trying hard to keep track of how long I have been here. Strange, fractured land.
Food and water not easy to find, but have enough for now. Ammunition more of a concern.
Distress call best hope for rescue. Will start gathering electronics. Saw some while looking for food. No idea if I can build transmitter, but must try.
