Hm. Well I once played a game that had something kinda like this. Maybe by reading this someone will get an ideal of what could actually be happining with this ghost. There was a huge and powerful beast. This beast devoured anything in its path. One day the beast devoured a small town, and afterwards the spirits still remained there. The people felt great sadness and hatred towards the beast, which is why they could not move on. One man tried to fight, but was killed. One woman tried with all of her might to protect her children, but in the end was devoured right along with them. Their souls were in pain. Their families, their friends, all were devoured. Of course this doesnt really have anything to do with Runescape, but I thought that maybe this would give somebody a clue about whats going on. I was on my way to examine this situation, but I died. :
