Lunaria

Lunaria is the city on the moon. It is where most of the events of Over the Moon take place.

As the song Ultraluminary states, when Jade and Chang'e arrived, it was a desert, then Jade made a potion ignite and it created Lunaria.

Fei Fei's dream was to go to the moon & the city to prove that Chang'e exists. Along with Bungee, Chin and Croak they encounter Lunaria after crashing on the moon & are taken their by The Lions.
