There is none the less nothing that would currently suggest Zodiark had any control over the matter. We've seen numerous instances of tempered individuals doing things their primal either doesn't know about or doesn't condone. Even Ramuh, a primal expressly opposed to both tempering and sacrifices, involuntarily tempered a bunch of sylphs that then kept doing things - including amassing more crystals - in his name.

So uh.. Last question, I guess. Where do people keep getting the idea that the life created by Zodiark was sentient and/or sapient? There's no evidence one way or the other yet.
