His legs flew out from under him and he started slipping and sliding down the damp tunnel. He yelled in pain as his arm cut against a sharp rock.
His hands scrabbled uselessly at the passing rocks as he flew by. The tunnel curved and twisted like a slide. Aang gripped his cut with his other hand as hard as he could bounced and jostled along. The cave seemed never ending, but as the saying says: what all must go up must have an end. The walls melted away,and the tunnel ended in a shoot. Aang with the momentum he had gained skid a few paces before stopping, and he stood up. His hand still holding his wrist in a death grip he looked around.
