"Despite its bipedal shape, the lisk is actually a carnivorous species of warm-blooded reptile suited to cold-weather climates. The “hairs” on its head and torso are in fact sharp, fibrous scales that help protect it from low temperatures and larger creatures. Sentient species are often surprised at how vicious a lisk can be, as its wide eyes and childlike grin give it a harmless appearance. The lisk’s two pairs of eyes are operated by different hemispheres of its brain, and are integral to its survival while sleeping. Only half of the lisk’s body falls asleep at one time, allowing each pair of eyes to keep watch during half of its sleep cycle."
