Lovecraft - Nameless Larva of an Other God

Progeny of the Other Gods, that hasn't reached proper age yet. In the outer space of Dreamlands these seem to be as common as rats. on Earth however, the'd be much more rarely encountered, but Dark Young of Shub Niggurath and Whateley Twins would seemingly get into that category.

"Never before had he known what shapeless black things lurk and caper and flounder all through the aether, leering and grinning at such voyagers as may pass, and sometimes feeling about with slimy paws when some moving object excites their curiosity. These are the nameless larvae of the Other Gods, and like them are blind and without mind, and possessed of singular hungers and thirsts."
