Jupiter Geographic Location in Yonderverse | World Anvil


Jupiter is a planet in the Kinosmo System, the fifth farthest from its sun, Aquarius. Jupiter is home to the Jovian, a species of powerhouse aurvad that has dominated space in their solar system, and has taken over Earth.


Beneath the rolling orange clouds is a paradise of shimmering blue pools floating between large boulders that glide through the seemingly endless skies. Jupiter's fractured core has resulted in trillions of floating islands, all woven together by water, as gravity on this planet seems to have stopped working.

The floating islands greatly vary in size. Some of the more populated islands reach up to 50 miles in diameter, while the majority are between pebble sized and just enough to walk on. These islands are comprised of multiple layers of rock; granite, bedrock, sandstone and quartzite are just a handful of the stone types that make up these floating islands.

Because some of these stones are less durable than others, cave systems can be found on almost all of the significant floating islands. These layers of rock never exceed more than twenty metres long, making for some truly breathtaking patterns on some islands.

Jupiter's Edge

The hollow sphere of clouds that surrounds this planet are known as Jupiter's Edge. This ball of cloud is at least a hundred kilometres thick, however this does vary a fair amount. The water vapour that makes up these clouds are orangey/brown, and are almost transparent. Light can easily penetrate Jupiter's Edge, otherwise flora and fauna would not have been able to exist on this planet.

Rollen Ring

A large ring of islands, known as the Rollen Ring, are situated on the border of Jupiter's Edge along the Equator. This ring of islands contains three major jovian cities: Eldereh, Isuauh, and Mire City. These three cities have a total population of 350,000; almost 5% of the entire jovian population on the planet.

This ring of islands is often considered the capital of Jupiter, thanks to its highly advanced technology and is the locatin of Jupiter's Space Legion. Jupiter's Space Legion is widely known in the Yonderverse, and because of it the Rollen Ring is one of the most known natural landmarks of the Kinosmo System.


Jupiter is currently 4.603 billion years old. At its creation, Jupiter was nothing more than a collection of asteroids. As the forces of gravity pulled in gases, Jupiter grew, and at some point it grew so large that gravity simply stopped working, and the planet was frozen in its shape, which is still remains in to this day.

The first life on the planet were small microorganisms that started appearing just a hundred thousand years after the planet froze in its shape. These organisms were incredibly simple, but quickly began to evolve. The first era, the Ichthyan Era, was named after the first vertebrate animals evolvesd - fish. These fish were very simple, but nevertheless were the planet's first complex organisms. Many existing intelligent people theorised that Jupiter would become a land of fish people, but this was quickly disproven during the Ichthyan Extinction.

This extinction occurred 4 billion years ago, when a city-wide asteroid hit what is now known as the Great Red Spot. This asteroid disrupted the lack of gravity in Jupiter, and caused the formation of the floating islands that is synonymous with the planet, as the asteroid shattered a part of Jupiter's core.

Life quickly bounced back, as it always does in the Yonderverse after an extinction-level event. The new life on the planet were prehistoric reptilians. These serpentine beings grew to extraordinary lengths, as they were perfectly suited to life between these floating islands. These animals formed an order known as serpentecorna. These animals thrived on Jupiter for a billion years before their extinction level event known as The Great Darkness.

A scientific mystery, 3 billion years ago all of the moons of Jupiter became tidally locked with the sun, Aquarius. This meant that these moons blocked all light that reached Jupiter, and flora and fauna species quickly died out or found other ways of obtaining energy. As serpentecorna are all cold-blooded, they quickly died off since they relied on sunlight to survive.

Life took a while to return to its normal state after The Great Darkness. Moons returned to their traditional orbits, and fauna and flora species began flourishing once again in the sunlight. Many animal species once again evolved to become reliant on sunlight; many animals grew large sails to absorb more energy, or to shed it when they had too much.

The final extinction-level event to occur in Jupiter's history up until today was The Great Scorch. Aquarius experienced a sudden increase in radiation which seemed to only affect Jupiter, curiously. As a result, temperatures on the planet greatly increased, rivers and lakes dried up, and fauna and flora could not adapt quickly enough.

As a result of this event, the aurvad class of animals were left to rule the planet, and they did. These warm-blooded, egg-laying animals could keep themselves cool, could warm themselves up, could lay hundreds of eggs depending on the species, they were perfect.

Only 7 million years ago did the jovians rise. These recently evolved aurvads were flightless unlike most, yet they had two incredibly strong pairs of forearms. These people were considered brutes, especially once they developed space-faring technology and began exploring other planets to rule. Unfortunately, their intelligence did not match with those they met, such as Mercurians. Jovians were quickly thwarted, leaving them running to hide on their own planet.

Jovians didn't leave the planet for three hundred years until news spread of the Neptunian's extinction. The planet Neptune would become a Harvesting Planet a year later, and then any planet would legally be able to obtain Neptune and all of its moons.

After a year had passed, Mars and Jupiter went to war over Neptune. The Battle Of The Blue Flames lasted just 3 months, after martians easily overpowered jovians. However, this wasn't entirely a loss, as the human extinction went under the martian's radar and Jupiter managed to acquire Earth.

Fauna & Flora


There are millions of fauna species on Jupiter. The most common classes are birds, reptiles and aurvads, three vastly different classes. Mammals are uncommon on Jupiter but not unheard of; the same with amphibians. As for invertebrates, insects and arachnids are extremely rare but cephalopods and crustaceans are abundant, and are a staple in many carnivore and omnivore diets.


The flora on Jupiter can be compared to the flora in the Glitter Field - the climate and geography is somewhat similar, and like the Glitter Field, large trunk-like vines and flowers grow across floating islands, bridging them together.


Jovians are the only intelligent life form to have ever lived on Jupiter. This species first appeared around 7 million years ago in their most primitive form. Jovians are not known for their intelligence, however they have achieved space-travel which is more than most. Instead, jovians are known for their brute strength as they are easily the strongest intelligent species in the Kinosmo System, and one of the strongest in the Milky Way.

I love the detail you went into on the history of the species on Jupiter. :D
