Ouroboros Spine aeons exist in a myriad cast

Whatever kind of creature it was, Mordecai could tell it was more than definitely safe to say that it was disturbing. Sitri's shudder almost seemed exaggerated in the low light, but it was still not quite enough to deter Mordecai from giving in. As headstrong as he tended to be, it was bridled most of the time. But little and little, those bridles were giving up the ghost. His eyes returned to the surface of the water again, but no trace of the creature bothered to poke its head above to view them. Nor did it return for another drive by touching, either.

“So it's kind of fishy, then?” which all things considered, it had to be. But he still felt the question was warranted, because it wasn't like he had felt something go scurrying past him. No, it had definitely felt more slippery than that, reminiscent of a fish. Not waiting for a response, he waded further out into the cool waters in the way he had felt it go. If nothing else, Mordecai hoped it was more scared of them than they were of it.
