[@Garth] [i]It takes a few moments for Rockmar's eyes to adjust enough to see much of anything.  The only light is that which is trickling in from the opening.  But a few feet from the entrance, the serpentine spirals on the right wall give way to a mural depicting a barbaric warrior clad in a bearskin cloak and welding a heavy spear and shield. He is engaged in battle with a huge, demonic hound. 

The tunnel is 40 feet long, then appears to open up into a room, though it is currently too dark to see any details. [/i]
