Galaxy24 » Yonderverse Codex


All art in this article is made by me, Mochi :)

For the entirety of 2024 I will slowly be fleshing out the Milky Way with 52 new star systems. Following the rules here, I will be creating the basics of a star system each week. These are just notes, no fancy layouts or writing, sorry! If I end up writing more in another article, I will provide links to them :)

  • Every Monday, I create a star (or two, or however many I like).
  • Tuesday through Friday are designing points of interest, such as planets, asteroid belts, artificial objects.
  • Weekends are for making plot-hooks and adventures.
  • I hope to, by the end of this year, have many more interesting solar systems to potentially develop in the future!

    Week 1: Xauein System

    Star: Xauei

    Red Giant, 17.2 billion years old. Inhabited by sunfins, gold gobblers and a nasty sun spider. Has about 20,000 years left until it is destroyed by said spider. 2 orbiting planets and 3 orbiting dwarf planet.


    Kokhon Belt - Asteroid belt between Kokhas and Aton. Full of research stations, atonians staring at Kokhas from a distance. Lots of fuel stations next to the Trimite Highway.

    Kokhon Belt by Mochi

    Kokhas: Ice Giant
    173 moons, almost uninhabitable with no sophonts. Ice storm speeds of up to 20,000 miles per hour. It has a rocky core with no wind at all (the Eye of the planet).


    Aton: Ice Giant
    3 moons, two sophont species - Atonians and atomians. Atonians are primitive, atomians are very intelligent.
    Temperatures of Aton are far below freezing but the planet is a blend of water and ice - the water stays liquid because of magic. It is a tidally locked planet.

    (Read about the atonians)

    Dead Lordricarr: Wandered into the solar system and died of starvation. Now a hub for illegal trade and criminal activity.

    Plot Hooks/Adventures

  • Atomians have discovered unusual thermal activity from the frozen core of Kokhas, and are attempting to explore it.
  • The oanie have attempted to wipe out the atomians and atonians so they can claim the whole solar system - nobody knows why, but they seem very desperate to take control.
  • Week 2: Mythas System

    This solar system is inspired by Myth Cross!
    Star: Mythas

    Purple Giant, the brightest star in the Trimite Cluster. Exudes healing magic and anyone can survive in space in its orbit, even with no protection of any kind. 6 orbiting planets and 9 dwarf planets.

    Luphas: Seraphenic planet

    Bright pink planet, plentiful in phosphorus and neon. 1 sophontic species, the luphans. 62 moons.

    Luphas Camp - Series of trojan asteroids orbiting on Luphas' orbital path, 60° behind the planet.
    Blue Bullet
    Artificial research station owned and ran by luphans. Has an elliptical orbit round Mythas and watches for any sun spiders, destroying any that get close. Bright blue and can travel at blinding speeds.

  • 12 tectonic plates
  • 17 mountain ranges
  • 6,791 volcanoes
  • 619,733 islands.

    Plot Hooks/Adventures

  • An asteroid is on its way to hit Etetere in the next two weeks, mass panic with people scrambling to leave the planet.
  • Large streams of nebula apalous have been discovered in the Luphas Camp. Who will claim it first?
  • Week 3: Karkhas System

    Star: Karkhas

    A bright green main sequence star. Highly radioactive and has been halted by a stellamancer. Owned, along with its solar system, by Karkhala.

    Gilde XG - Giant golden asteroid. Half of it has been mined by the oanie.
    Mathas Ring - Giant asteroid ring that orbits the Royal Ring, which in turn orbits Karkhas.
    Royal Ring - Even gianter asteroid ring that orbits Karkhas.
    Khuanatashini - Oceanic Planet

    Has a large core but no landmasses. Cities previously formed on the backs of turtles and similar megafauna have been abandoned. The sophonts native to this planet left hundreds of years ago, leaving these gargantuan biotic vehicles tortured forever.

    Plot Hooks/Adventures

  • A radioactive virus has just been disovered within Karkhas, already having wiped out one colony of oanie. It is spreading faster and faster.
  • An oanie-led mission to save the turtle cities of Khuanatashini gives people hope that there are some good oanie out there.

    Planets are large celestial bodies, commonly found in close proximity to stars. They are the infrastructure of Aavar's River; almost all sophontic life has, will, and continues, to evolve on planets.

    Milky Way
    Geographic Location | Apr 14, 2024

    The largest galaxy in District 2.

    Story-Based Galaxy24

    Let's see what's first on my list... the Xauein System, hmm. Oh damn, it's not got long left. Twenty thousand years before the star explodes. Oh well! Better explore it before the place is gone.

    Stella stepped up to the window of her starship, admiring the beaming star Xauei. She slowly drifted toward the asteroid belt directly in front of her, softly landing on a large floating boulder. The ship's scanners went haywire as other asteroids flung past, along with a small fleet of peculiar little creatures. They had soft, squishy bodies, as they clashed and jumbled together in an unorganised mess. Several dropped down from their cluster to greet Stella as she stepped out of her ship, and she reached out a hand. They sniffed and snorted, quickly flying back to greet their friends and continue the animal's migration.

    Stella's biota scanner whirred to life as organisms were detected in the vicinity. She pulled it out and scanned these squishy animals, registering them as boloos. Off to a great start!


    Average Size: 7 - 40 metres long
    Average Lifespan: 400 - 1000 years
    Colouration: Pastel colours, often multiple and splotchy
    Behaviour: Passive - lacks the part of the brain that controls violence, so has 0 violent tendencies.

    One of the most common fauna in the Kokhon Belt, boloos are squishy megafauna. The part of the brain that controls aggressive behaviour is missing in this species, and they spend their lives floating around the asteroid belt and sucking up floating algae and expelling rocks that get caught in their mouths.

    Fauna | Feb 2, 2024

    The space equivalent of manatees. Boloos migrate round the star Xauei in large clumps, crashing into asteroids and one another.

    Oh no! Looks like the rest of the story is hidden. To read on, become a Guardian! You'll also get access to secret content in the Yonderverse, monthly updates of my writing, a fun reference within this world, and a special thanks on my supporters page.
