is a small planet mostly covered by water. Its vegetation is mostly grey and white, making the planet appear snowy from outside the atmosphere.
The planet is inhabited by a sentient race called the Hyaciori.
Caerula Scentrosha's sentient population was 420,936,220, but when the Thera Virus reached the planet, less than 0.5% of the population survived.
The SAS is unable to stop the virus, but it fades when all zombified Hyaciori are eradicated.
This planet's atmosphere has a very high oxygen content.
