The glowl is a man-sized, bioluminescent bat that lives in deep caves and hunts at night. The green glow of their body is caused by millions of tiny micro-organisms swimming in their bloodstream, which emit light when nervous system of the glowl informs them to. The glow is used to lure in animals, though this tactic does not work that well on more intelligent creatures. The glowl is also quad-optic, and thus has four eyes in its head, each of which can be independently controlled.
