In the beginning, Inferno wasn't the polluted mess it is now. It was once the most popular tourist planet in the Empire of Eden, boasting a pristine environment that rivaled untouched natural worlds. Such a lush and green planet naturally attracted the Celesterrors, who adored it.
Nearly all the Celesterrors in the Empire of Eden called this planet home. It was a major draw for both domestic and foreign tourists, but it also caught the eye of some unsavory characters.
An illegal research lab, known for capturing Celesterrors for experiments, secretly set up shop on Inferno, building their lab deep underground.
By the time the Empire of Eden realized what was happening, it was already too late.
Though they swiftly executed the criminals responsible, the damage was done. Many Celesterrors had been infected by the virus, transforming them into mindless creatures known as Fallen Beasts.
