@Olmec-Joe: do you remember that you found a blue version (the Sapphire Eye) of the green pearl in the Draracle's Caves? You opened up wall with it by placing it in a dragon's eye socket. The green one (the Emerald Eye) could have been used to open another path. This leads to another part of the Caves, so that you find another offering for the Draracle. Don't worry, you haven't missed anything; if you take the Emerald Eye path, the secret wall in the Sapphire Eye path will close, and if you take the Sapphire path, the secret wall will close after you've stepped through it. This way you can take only one path.
It's always a pleasure to help fellow Lands of Lore fans!
