Sao System

Sao is a small Solar System containing a single planet, the planet orbited by thirteen moons. The most famous moon is Twelve, as it contains possibly the largest metropolis in the Yonderverse, Stargazer City.
This single planet is name Echos, orbiting a Sun named Sao.




Echos is the only planet that orbits the sun Sao. It is a gas giant, home to a few sub-species of spirit orb that represent different gases the planet is comprised of. The planet has a stable core in the centre, which has lots of plant life growing on it. The rocky terrain is called home by some bacteria species, that co-exist with small reptile species that also live here.

Fauna & Flora

Sao is arguably the most biodiverse Solar System in the Yonderverse. Most noticeably is the abundance of sea creatures that live in a ringed Labyrinth Sea that circles Sao. There is an abundance of coral and plant life that exists on the many asteroids that have gotten caught up in the water, and because of that thousands of marine creatures have evolved from the simplest of cells.


Stargazer City easily attracts all the attention that this Solar System gets. The metropolis is famous for being a place that refugees want to go; offering simple housing and jobs, they can make a life for themselves, ignoring how lacking that life is however. The city's architecture is what brings in a ton of tourists, from all over the Yonderverse, those who find architecture interesting



One is the largest moon orbiting Echos. It hosts a small variety of plant and animal life, with moonfrogs and their tadpoles jumping in the pools, eating small insects that fly about.

Three is the third largest moon orbiting Echos. An incredibly cold moon, it is coated in snow, with mountains, valleys, some valleys that reach straight through the moon and reveals on the other side. The moon hosts a small variety of creatures, a lot of herbivorous mammals that feed on the short grasses and bushes that grow practically everywhere.

Five is the fifth largest moon orbiting Echos. The planet has no life except for a single species of bacteria, called spectrills. This bacteria covers the entire moon, every crater, cave, mountain. The bacteria's most noticeable property is its bioluminescence, from afar Five is brightly coloured, the bacteria produces a hypnotic array of colours that initially confuses anyone who spots the moon.


Seven is the seventh largest moon orbiting Echos. Seven is known as a blood moon, as the rock is comprised of about 30% blood. This blood sometimes seeps out of the rocks, and in craters the blood will form lakes and rivers. A few species like to eat the rocks to get at the blood inside.


Nine is the ninth largest moon orbiting Echos. The moon is covered in a large jungle environment, which contains masses of species, ranging from the tiny squiffler to the humongous flying faldinns.


Eleven is the eleventh largest moon orbiting Echos. Instead of being a massive chunk of rock, eleven is a massive, complex being that is instead named "Puck". Puck is capable of speaking, and people have built a research facility on Puck to try and understand exactly what Puck is saying. Puck is not alone, with much plant life and animal life living on the moon Puck is able to communicate with it all.

Thirteen is the smallest moon orbiting Echos. It contains just a single plant species on the planet, rapidsnaps. Some species of insects that live on the planet have found ways to avoid being eaten, some will sit on their leaves and munch on them, or suck their sap with a proboscis.


Two is the second largest moon orbiting Echos. It has the biggest biodiversity of the thirteen moons that orbit Echos, with over a thousand insect species and a couple hundred bird species. The entire moon is a grassland populated with many trees, and the insect life has caused the population of birds to skyrocket. Some of these bird species include pocklets and saffronbeaks.

Four is the fourth largest moon orbiting Echos. The moon is covered in one single, massive tree, that has roots extending deep into the rock and above ground growing into massive mangrove trees forming a swamp environment. The roots of the trees form tent shapes underneath them as the trunk only starts a few metres above the ground, which gives a perfect place for giant insects to weave their webs between the branches.

Six is the sixth largest moon orbiting Echos. The planet is overrun with small moon mice, which consume the very moon that they live on. Once they die they'll eventually decompose and become part of the soil, which means the moon decreases in size very slowly. This moon is also a bright yellow, because of a variant of the spectrill bacteria that only glows yellow.


Eight is the eighth moon orbiting Echos. Or is it? Eight is actually a complete illusion. Eight is not real, but one always does until you go straight through it. The moon is theorised to have been created by a deity or some incredibly intelligent sentient being to disguise some hidden secret where the moon appears to be, but nobody really knows.


Ten is the tenth largest moon orbiting Echos. It is a completely desert moon, with a sandy ground and absolutely no water at all. All of the animals and plants that grow and live on the planet use photosynthesis to get energy to survive, and they do not need water to survive either, thankfully.


Twelve is the twelfth largest moon orbiting Echos. It one of the only moons with sentient life, a metropolis named Stargazer City also sits on it, one of the largest metropolises in the known Yonderverse. It is one of three moons without an atmosphere, and so there is little plant and animal life to be found on the moon.

So much diversity! I think my favourite is the moon with the massive tree, number 4. Maybe because it reminds me of le petit prince!

So many interesting species across all the different moons. I'm really curious why sentient species chose a moon without an atmosphere for their city. :D   Also got to love their creative naming theme of the moons. :D

I'm so glad you like all these moons and species! Regarding the city, I honestly have no idea, I never took into account there would be no atmosphere xD

Oh boy, all these moons are interesting ! Hey, since Six becomes smaller, does that mean it'll be smaller that Seven one day ? Will they then switch names, or keep them ? Also, it would be nice if you used the moon names to give links to their articles

I don't know what doped-up Gods made this system, but honestly parts of it sound creepy enough that I propose triggering a supernova.
