In Star Fox Adventures, Cerinia was reported to be completely destroyed. The only known survivor of this catastrophe is Krystal, who originally came to Lylat, and later Sauria, searching for answers to the destruction of her homeworld.
Absolutely nothing is known about the planet's environment, history, its overall natives and respective cultures, as well as its true fate. This is because Cerinia is referred to only once in the beginning of Star Fox Adventures, and is never mentioned again. It is currently unknown whether Krystal herself is still interested in investigating the fate of the planet.
- Cerinia's name is not actually mentioned in-game. Nor is the fact that Krystal's entire planet was wiped out, instead only making reference to the deaths of her parents. The information about her planet actually comes from the instruction booklet for Star Fox Adventures.
- Krystal and her family may have been of high status on Cerinia. This is implied by the various symbols and tattoos decorating Krystal's clothing and herself, as well as by her mystic staff, and gold-white clothing.
- While unconfirmed, Krystal's reaction when she saw a mysterious figure shortly before being trapped inside the crystal in the Krazoa Palace implies that Andross may have some part in destroying Cerinia. It is possible that he did so and left Krystal as the survivor because he needed her power to use the Krazoa Spirits' power to revive himself (and therefore only needed a different villain to become powerful enough to invade Sauria in order to get both Fox and Krystal releasing Krazoa Spirits). Another theory could be that Cerinia had spiritual energy akin to that of Sauria, and that he attempted resurrecting himself there first, but failed and it resulted in the planet's destruction. A crucial plot-point of Star Fox Adventures was that Sauria was in danger of exploding and needed to be stabilized by the energy of the SpellStones and Krazoa. The idea that Andross was responsible for Cerinia's destruction is further supported by the fact that Krystal seems to stop searching for answers to the demise of her home as soon as Fox kills him (apparently for good) and Sauria is saved, as well as Krystal's odd aggresive reaction towards the Krazoa God (Andross) upon it being unveiled.
- How Krystal escaped her planet's destruction, is also unconfirmed, however the events of Star Fox Adventures do show her being able to pilot her own ship, which she uses to reach the Great Fox in order to thank Fox for her rescue. Whether this same ship is what she used to escape Cerinia and reach Sauria is unknown, though the same model of ship was seen in SharpClaw possession during the capture of Prince Tricky. Unless of course, it was the exact same ship and it either belonged to Krystal and was found and briefly taken control of by the SharpClaw during her imprisonment at Krazoa Palace, or it was given to Krystal as thanks for her attempt to save the planet.
