Pan was the Ancient Greek god of pastures, flocks, the mountain wilds and rustic music. In Rome, he was called Faunus. He had the body of a satyr (legs of a goat and body of a human). He was also known to produce a sound called a "panic" that caused extreme pain to any who heard it, this sound is the origin of the English word panic. He was the lord of the wild and as such, all forest dwelling creatures answer to him, including (but not exclusively) satyrs, nymphs, and forest creatures.
