Asteroid Moira, is, in actuality, one of the gigantic mineral creatures which inhabited a planet before it exploded, forming the asteroids. Somehow it survived the catastrophe, and, forming a hard, crustaceous shell about itself, has continued to live in space as an asteroid. It is apparently highly intelligent and has acquired an appetite for human flesh.

A small, oddly canine-like creature with telepathic powers, a space-dweller which men found when first they came to the asteroids.
