I have spent countless hours exploring this zone and I have enjoyed hunting there. However, I have been unable to figure out a single quest. I have discovered the sarcophagus on the lower level and I noticed the scarab-shaped indentation, but I was not able to unlock it with a scarab or use the scarab in any useful manner. I found the pouch with lions on it as well as the dagger dropped by Ramainen. I have not been able to figure out if the keystones on the upper level server an function or if they are just decorative. I'm wondering if someone can give me some hints to point me in the right direction. Do these items actually have a function or am I just driving myself crazy for no reason? Is it possible to have quest items that do not actually serve any purpose?
