After killing many shadows i collected mazzy but sent her home i then solved the riddle with the talking statue and recieved one of those disks of which u need three . i do not know where the other two are and i cannot continue through the door without please send any hints to ther where abouts!

Welcome to IW!
Do you have the light stone as well or have just received the holy symbol in pieces part 1 of 3?

i ave two of the three but still missing one and i ahve that sun gem but i dont know where i ave placed it because it seems to have dissapeared while i have been in the dungeons

You receive the first part from the statue.
The second from some ghosts right after the lava pool if you have the bones of the child prophet with you.
The third one is across the room with the letters on the floor where a shadow asks you to carry it to the other side.In a small cornrer of this room is the third piece!Really easy to overlook,yes? :D
