One glance at a beholder is enough to assess its foul and otherworldly nature. Aggressive, hateful, and greedy, these aberrations dismiss all other creatures as lesser beings, toying with them or destroying them as they choose.
A beholder's spheroid body levitates at all times, and its great bulging eye sits above a wide, toothy maw, while the smaller eyestalks that crown its body twist and turn to keep its foes in sight. When a beholder sleeps, it closes its central eye but leaves its smaller eyes open and alert.
