i dont think it has anything to do with the point the game started there. why? well i not even played the game to an end and already saw 3 such swords. the one is the same as where wyutse found it. the second one in the catacombes in aleroth(4th level, in SW of the room where you go to level 5) and the third one i cant remember. when i saw that sword i had already seen the one in the catacombes and so i think its just cause its already been seen on another spot. first i tought it could show there is a secret passage between them or something like that but after hours of resaerch still nothing.
