Cerasucs are large, furry mammals that live in deep caves and are often found in groups of 10 or more. They have a black coat and antlers that are prized for their ability to reflect light and light up dark spaces. They have excellent night vision and their hearing is also very acute, allowing them to sense predators from far away. They forage for mushrooms and other underground plants and make nests out of sticks and vines.

These strange creatures have a stoic, aloof demeanor and very little interest in other species of animals. They are very shy and skittish creatures that go out of their way to stay away from humans, but will attack if provoked or frightened.
