Problem... Grimm evaporate when killed. If the moon was a giant Grimm that they killed, it should be long gone. I mean, for everyone to have forgotten the stories, it would have had to have happened many generations ago. Even if it takes longer to evaporate because of its size, you'd think enough time would have passed.

Maybe it's still alive and lying dormant, but that begs the question of how one fights a moon, even if they did once have a fuel source besides Dust.
