I've been running laps around this accursed dungeon for 2 days now. I have 2 glow stones, I have 1 tablet. I know where the library is and where the revolving room is. I can't figure out how to open the other doors to the revolving room. This place is one big dead end!

Please tell me where I need to look to find the north hallway and the remaining tablets -- this is getting very frustrating.
