Room 13 - The Locked Door
This door is securely locked. If you grab the keys from the calacorn's table, even they will not turn in keyhole and thieve's tools do no good against the solid tumbler.
A reptilian hiss behind you mocks you, "Ha... only Nandras can get in there!"
"Without his keys you're stuck here keeping us company."
"Whichever you prefer."
Doors lead west and east from the room.
If you have the Crystal Key from Nandras, then you use it to unlock the door and proceed north
