Their own societies are sparse, since they reproduce by infesting the lingering psyche of their victims asexually with their larvae, which pupate in the subconsious of their dead minds, which in this setting are still capable of dreaming. Gatherings of Ombryx usually only happen if neither parties know that they are dealing with another Ombryx, due to their convincing costumes.

Ombryx too suffer from the effects of bias on their perception. Their frames of reference are based on the mind they grew up in, and are effectively the exact same as that of their "parent"'s victim.
