Small, flying creatures with sharp features suggestive of a young aelth. They fly, and sing a strange, warbling song. Their song is psychoactive. Targeted creatures that hear the song will become fascinated by the creatures, hold them, pet them, and feel intense pleasure. with longer exposure, or exposure to multiple creatures' songs, victims will essentially freeze in place, paralyzed with ecstasy. At that point the singers will begin to feed, flaying strips of flesh and eating them. They feed in groups, but take their time.
Singers are roughly humanoid, about one foot high, with bat like wings. Their skin is silvery, with shimmer and highlights that range through a rainbow of colors. Enormous pearlescent eyes, tiny and viciously sharp teeth, and long razor-sharp claws. They nest in forests, in groups of a dozen or so.
