The three moons of Terrinor are named Galemon, Keror, and Yuzla. All three of the moons around Terrinor go through phases, like the moon around Earth does. All phases start with the adjective "waxing" (meaning increase) as they flow into the full phase. After the full moon phase passes, it will start with the adjective "waning" (meaning decrease). Crescent is when there is only a small portion of the moon remaining and gibbous is when it's almost full. Below is a chart that shows the phases in order.
