I put forth a theory quite a while ago that the moon itself is a creature of Grimm, sort of like the Brother moons from Dead Space 3.

Now that I think about it, it'd be kind of badass if at some point in the distant past the pollitical climate on Remnant had gotten so bad that a moon-sized Grimm was attracted to it and introduced the Grimm to the world. Then a massive war for survival broke out and the final battle was on such a massive scale that they managed to kill the moon-sized Grimm through sheer force, leaving only it's "shell" in orbit. Such a war would undoubtably leave humanity in a pre-industrial state and reduce the true history of what happened to disjointed myths and legends. (Silver-eyed warriors actually being supersoldiers, the Maidens acting as defenders for the new colonies(now Kingdoms), etc. etc....)

That's probably not why the planet's called Remnant or even true in the slightest, but that's why it's called speculation.
