Pull
You pull at the protrusion and you hear a soft click. The bookcase swings forward by just a fraction letting you know that behind it, there must be a door. You look at the wolf-lady but she went back to reading. You slowly, carefully open up to reveal the darkness behind the bookcase and slip through. As your eyes get accustomed to the darkness you make out a long twisting tunnel with the brickwork still exposed. The floor is mostly sand with the occasionally lost tile to stub your toe against. Thin glass pillars lodged inside the ceiling every so often let in long rays of light speckled across the path. You follow the path as it descends under the streets, deeper and deeper into the unknown. You walk into a heavy curtain made from stiff velvet. After a moment of disorientation, you slip past it into a large cavern. Gray rock infused with red stripes lines, reminding you of veins. Your footsteps are padded by the sand underneath your feet and the man that is pacing around the room busily working on some unknown project hasn’t got a clue you’re here.
