Ouroboros Spine muse

He loved the vibrations his siblings made.

Stratos had been asleep when his sister started to cry. His ears, of course, were yet too young to hear the sound of it, but in the moments between sleep and awareness, he could feel the faint tremors ripple through Callyope's tiny body as he dozed beside her.

Like his sister, he had no need to cry, but her soft voice roused two things in the child: an instinctive want to soothe her, and a want to make vibrations of his own. So he nuzzled against her to try and solve her problem, as all the while he let out his own newborn voice in some warbled kind of infant song.
