I saw this once, and haven't particularly been looking for her again, but there was a blue, semi-transparent sprite of a woman who appeared at the body of land in the lake on the bottom-right of the map. I tried to reach her, but since I saw her early in my playthrough I had no way of doing so. However, it's now much later in the playthrough and I still can't see any way of getting to this area. How is this area meant to be accessed, if at all? Has anyone else spotted this ghost character in this area, or in any others? Any help is appreciated.
