Personally, I think that Monty is telling us in as plain language as possible that the moon heralds the Grim's return. (Whether Grim is a really powerful monster or the entirety of monsters that will return remains to be seen) I personally would be shocked to find that this is not the case, although with Monty anything is possible.

The only question is how quickly the moon is breaking apart. The trailers and the first episode seem to indicate its happening quickly, although no one seems to find this odd, which casts doubt on this theory as people would be much more worried. They also shows that there is more than one moon. The extremely demolished moon you see as Ruby fights Roman might be a third moon that we haven't seen in the trailers.
