Memory:Eye of destruction

This member of the floating eye family feeds on the disintegration of substances, possibly deriving energy by destroying the bonds that keep things together. Objects or creatures that come in contact with the creature may be destroyed beyond recovery, and so these creatures are feared by all who value their possessions. An eye floating in mid-air. You'd think that it only could observe its surroundings - until you see a bypassing fly being caught by the gaze and instantly getting dragged into the pupil, vanishing without a trace. You grip your belongings tighter, lest some of them attract that possessive attention.
