They wax poetic, with sullen eyes and long flowing hair. Their existence is a hard one, yet they feel it a necessary undertaking. They travel deserts, trek mountaintops, cross rivers, valleys and lakes to spread their message of truth to scores of devoted (mostly paying) followers. They give hope to the hopeless, they can assuage your fears and touch you at your very soul, to the point where they can make you believe they have seen what you have seen and felt what you have felt.
They are musicians, and they are the modern day prophets.
