Fifty feet past Bible, up a sloping and twisting tunnel, there was a high ledge. On that ledge, Jack and Tenibor could hear a deep grinding, breathing sound that could only come from two sleeping stone giants. How they had slept through the sound of battle was perplexing, until one remembered that the sound of dwarves and orcs digging while orogs beat them was not unlike the sound of battle. (In particular when it echoed up a rocky tunnel.)
