Man-serpents are huge, snake-like creatures with human heads. Their "hair" is a mass of tiny snakes, and their face often emits an unearthly golden glow. They are cold-blooded with glittering black scales and grow to an adult length of 20 to 40 feet. Wise and patient, these creatures can stay still for hours but move swiftly when alarmed. They favor resting in a semi-aware state that conserves their energy and makes them very hard to surprise.
