At the beginning of the game, in the catacombs under Aleroth I saw a folded sword on the ground,and if I remember well there was a dead man near it. I thought it was strange, but i kept going on my way. A few time later, near Aleroth I found it again with a corpse near it, and my character said something like "seems familiar to me".
Again, in the datk forest, in the elven village all npcs have been killed and what i found near the corpses around the fire? That folded sword again!
Now...Is that connected to some quest? Is there an assassins that leaves this sword on the ground as a mark of his "work"?

p.s. in the dark forest I freed the ghost of the sword of the stone, then I left the area and the ghost killed the two people in the camp near the road. But that strange sword on the ground make me think it wasn't the ghost who killed the elven people.....
