Greater fox-like bat (Astridopteryx microtis) is a species of bat commonly found in large caverns of Nidavellir. It has medium long, black to light brown or gray fur with their nose, ears and legs lacking this fur. Their snout is what gives them the name since it resembles the nose of a fox. Inside of their ears glows in a blue light which is gained via bioluminescence which it gains from eating large bioluminescent insects (example: Lampyridae animalux) which are attracted to the light from its ears.
