Light green moon?
Every dimensional world had its own moon, just like the abyssal world's red moon that had been consumed by Forage Moon and became its puppet.
Forage Moon did not consume all the energy of the moon but just made use of its body.
It could construct its own energy using the roots of the moon's body.
This was the only way Forage Moon could truly take control of the moon for the Moon Empress' usage.
Hence, although the Moon Empress had taken the red moon from the abyssal world, the power from the red moon still remained in the abyssal world.
Although the dimensional lifeforms from the abyssal world could no longer see the red moon in the sky and use it to keep track of time, the abyssal world was unaffected by the disappearance of the red moon.
The environment in the dimensional rift was a projection of the environment in the dimensional world.
