Friar William goes through stone-cracking cold, frozen toes, and the threat of demons to reach the camp of Mongke Khan. There, his interpreter causes him more problems, and he falls into the bizarre religious life of the camp before being drawn into a debate between Muslims, Buddhists, and Christians before the khan. Thanks for listening!
