Exio
Geography
While there isn't much in terms of geology, as the planet lacks a core, many biomes have formed along the tree-like rings that grow around the planet. These rings circle the entire planet, some thousands of miles wide, cave systems within them. Exio contains a multitude of biomes and climates, ranging from the freezing core to the methane-filled toxic pools of the surface.Frozen Core
While there is no fixed core, a small sphere of water mixed with flakes of ice can be found in its place. Known as the Frozen Core, this biome contains a distinct lack of unique animal and plant species, and instead houses very few populous creatures. The core reaches temperatures of about -5℃, fairly warm for most oceanic planet cores.Copper Swamps
The Copper Swamps are found about 60 miles deep, and are illuminated with molten copper specks. This metallic water is home to an abundance of plant species, that thrive in the mineral-rich environment. The Copper Swamps are the only place the sirenfish can live for an extended period of time, and their entire civilisations are based in these areas.Methane Pools
The Methane Pools appear as moving green blobs on the surface of the planet. These pools are extremely toxic, as any interaction with bare skin will result in severre burns, and the risk of methane oisoning. Little life exists in these pools, most of which are bacteria and small microorganisms.Exio Rings
The seven gargantuan rings embedded in Exio are known as the Exio Rings. These rings are actually one singular plant species, that will only reproduce as it dies. These rings are the source of most life on the planet, as many flora and fauna species rely on these rings to survive as they give off a healing aura.Fauna & Flora
Fauna
Like most oceanic planets, there is a great amount of animal life on Exio. The most famous species is the sirenfish. Sirenfish are classified as sophonts to some, but not to others. Despite what some think, sirenfish are incredibly intelligent but unfortunately use it for devilish purposes.
Sirenfish enjoy sneaking on other planets in small spacecrafts and causing a nuisance to locals, as their shapeshifting abilities are oddly enhanced out of water.Flora
Aside from the Exio Rings, there are too a significant number of plant species on Exio. Most plant species exist on the Exio Rings, forming symbiotic relationships where the Exio Rings are provided with a small amount of nutrients, while the other plants are given a sturdy place to call home.
Scientists have attempted to study the plant life on Exio, due to their unusual symbiosis, but unfortunately the resident sirenfish enjoy scaring any foreigner out of the planet, or instead just eating them.
The Copper Swamp sounds kind of beautiful in a weird way. On the other hand, the sirenfish sound terrifying.
This planet is one of the creepier ones, but unfortunately it doesn't sound too creepy in the article D:
