Clouder

A long pool made of marble stone sits in the center of room 7/29. Water as dark as a night sky fills its basin. If an adventurer drinks from it, they get a vision that changes depending on the phase of the moon that day. If it is a new moon, they are revealed a terrifying truth. If it is a full moon, they are provided a clue to a mystery perplexing them. On any other night, they receive a vision of a clear night sky, with the moon in its current phase. Strangely, the moon is whole and unbroken.
