Yes. That would probably make the most sense. I noticed it too, while playing it. I thought about it for a while and used eoch to check out your hypothesis. It turns out, you are indeed correct. Where the Black Omen, Melchior, the landing point of Lavos, and Belthasar are, that's approximately the location of a temporal distortion. Plus, not to mention the fact that in those approximate areas, there seems to be sme sort of time gate, if I'm not mistaken.
