There are some people who claim to remember seeing the ghost, probably during alpha, but nobody seems to have any screenshots or video. Funcom - in my recollection, but I cannot find it - said they actually looked for her, but couldn’t find any files for her.
I’ve been looking for and posting about here for some years now, to no avail. Eradication later made a video about it. Some information is posted here:
My current impression is that there was a ghost, but with no voice files. That would explain why they cannot find any files - if it was a generic ghost with no text, there’d be no identifiable information about her. And it would also explain why the ghost was removed: It was only half-done, so they removed it before release.
One player has recolletion about a song, though:
It’s a mystery.
Sadly, that seems to be the case for many lore elements. How, for example, did a part of the Sandstone get to be eaten by a large crocodile? There are so many loose ends in the story…
If I knew how to mod, I’d like to finish all the wholes in the lore. Xevyr, Hosav and others have fixed many of the mechanical elements of this game. But the lore… oh dear.
