As you slide the red bound book out from the shelf it resists your effort until a click reverberates through the wall. An almost inaudible scraping of stone alerts you to a section of the north wall that slides down into the floor revealing a dimly lit entrance.
Inspecting the passage beyond the archway closely you see that it decends as a stairway tightly spiraling down with only occasional torches lining the wall to shed their tawny light.
Do you decend?
