Winter velns hide from predators by appearing flat or misfigured from a clever use of optical illusion camoflage, but they're actually typically very fat creatures. They eat snow and do a sort of reverse-photosynthesis, producing energy from darkness. Because of their plumpness, veln are a prized delicacy for almost every other creature in the famined tundras they inhabit. They strictly stick to a "reproduction cycle" that occurs approximately every six years, laying anywhere from sixty to eighty eggs per nest.
