The 2nd largest moon, about 3 times as large as the Young Moon. The moon derives its name due to its shining blue hue, and astronomers have observed its surface to be covered in crystalline structures. Its cycle takes 125 days, an entire seasonal year. The moon is brightest on the first day of the seasonal year, and is darkest on the 13th night of Nox. Culturally, the moon represents intelligence and wisdom, with a common belief that one thinks the clearest on nights when the Crystal Moon is full. In Dichotism, the Crystal Moon is believed to be the god Galbator.
