Upon solving the Defiled Temple puzzle, a sealed passage will open, and it leads to the Underdark. This area plays an important role inBG3’s Find the Nightsong quest, and players should be prepared to battle some challenging enemies as they explore it.

With respect to how the solution to the moon puzzle is determined, there is a journal in the Defiled Temple that is intended to pointBG3playersin the right direction. That journal can be found in a cabinet next to a bed, and it indicates that the full moons are to “match the stars” and darkness “belongs at the bottom.” This leaves just the half moons to address, and those take their positions on the left and right sides of the puzzle.

One final thing to say about the moon puzzle is that it is actually possible to open the way to the Underdark without ever solving it. Indeed, there is a lever on a nearby wall that can be lockpicked to clear the path. However, players will need to perform a successful Perception check, which can be triggered by moving theirBG3partynear to the sealed passage, to reveal that lever. Fortunately, fans can always turn to the circle puzzle if they are unable to put this alternate approach into motion.
