I was trapped in the tunnels. No matter which direction I ran, I hit a dead-end. The ground trembled underpaw, and the ceiling shook overhead. Clods of dirt pelted me, and rocks dislodged themselves from the walls and tumbled down, slamming my skull and ribs. Claustrophobia bubbled up in me. I tried to scream, but got my lungs full of dust and started coughing before I could make a sound. Up ahead, white, glistening things moved in the darkness. Bile rose in my throat as I saw what they were. I stumbled back and felt the wall of brambles close around me, tearing at my skin, trying to rip me open.
