This is a proposed tweak to the moon puzzle solution (the one gating the underdark in the goblin camp) so mega spoilers ahead.
The trick to this one is noticing the beam of light hitting one of the circles in order to properly place the colored moons. The thing that bugs me is that the black moons go in the beam of light while the white moons go in the opposite circle.
Why not reverse the two? It makes more intuitive sense to me to match the white moons to the light beam, as lit objects tend to be bright.
Maybe I missed a clue in the environment; maybe there’s something to the Selune sigils I didn’t catch. Still, I feel the challenge of the puzzle should be in manipulating the moons rather than figuring out the proper combination. It’s just as hard to get the moons in the wrong order and very tedious to switch them around once you’ve realized your mistake.
