Dream World

''"I live in a place called the Dream World. No, not Dream Land, the Dream World. We simply control people's dreams. We choose what's in them and what they mean, sometimes to send a message to someone." ''- Luna, in CFA's pilot episode

The Dream World is another dimension run by Luna. The Dream World sages are responsible for the upkeep of their world and also for giving their world's residents good dreams at night. The Dream World also takes care of planet Pop Star  via the Fountain of Dreams that is located in Dream Land. However, no one from Dream Land is a sage.

Sages of the Dream World
Sages are usually the ones that do the fighting in Cloud's Forum Adventures. However, they rely on the Dreamstar's power. If something becomes amiss with the Dream World, Luna prevents anyone from tapping into the Dreamstar's power for security purposes, preventing the sages and anyone else from tapping into its dreamy energy. However, during Luna's possession, he did not prevent anyone from tapping into the Dreamstar's power, ultimately leading to his defeat by two of the sages.

Dreamstar
The Dreamstar is the Dream World's most sacred artifact. Nobody knows if it is sentient or not, but it controls all of the dreamy energy that channels through the Dream World on a regular basis. It also grants dreamy powers onto the seven sages of the world: Cloud, Blue, Luna, Spectra, the Soul Star, 11tailedwolf, and DragonSoul. Luna is required to watch over the Dream World during his free time to prevent someone from entering and stealing / tapping into the Dreamstar's power.

Trivia

 * The Star Rod of Dream World is the artifact that allows Luna to access Pop Star. If the Star Rod is taken, Luna is unable to do anything to help Pop Star should anything happen.
 * The Dream World was originally designed as a place with light-blue ground with star textures with a black sky. However, this was scrapped.
