Just to be clear, the reference to the Two Moons isn't a direct reference, so there's no problem there, it's just a metaphor which the player will have to figure out. I did a bit of research and the positioning of the moons has extremely relevant meaning. The player will have to discover this fact and figure out not only where to go to investigate the death cult, but also when to go there.
