The Solum System is a system of moons orbiting the rogue gas giant planet Solum in the Mid Arm of the Ambrosia Galaxy. It was discovered by the Ugnara Kingdom and used as grounds to stage an eventual invasion of the nearby Hope System in 10465 CE during the Ugnara Wars.
Solum is quite a unique rogue planet. Because its atmosphere is a dark grey color, and it exists within the infinite darkness of interstellar space, the planet should be barley visible. However, due to its closest major moon, Oblivio, the planet glows with a distinctive hellish orange red color. Solum has spent the majority of its history in this state.
The reason for this is that Solum inflicts immense tidal forces on the moon, increasing the temperature, and volcanic activity on the moon extremely, making the moon emit star-like light. And, since the gas giant is tidally locked to the moon, it exists in a constant state of "day." Due to its strange relationship with Oblivio, Solum, and its moons, are a very popular tourist destination for extra-galactic travelers, entering the Ambrosia Galaxy. As well as intragalactic ones. The planet is mainly comprised of the gases hydrogen and helium. These gases are mined and processed from robotic probes sent from the Oblivio colony, Infernium.
Solum formed from the planetary accretion disk of its parent star around 4,127,109,000 BCE. Its two moons, Oblivio, and Etiamteamo soon followed. Around 3,999,666,333 BCE. Solum's home system would cross into the orbital path of another star system, this caused many of the celestial bodies in both systems to have their orbits radically changed. Solum however, was completely ejected from its home system as a result of this. Once it was ejected, Oblivio would be hurled in very close proximity to Solum. With this, the moon would be piratically torn apart by the planet's extreme gravity and tidal forces. This caused the moon to become a volcanic hell world of lava and magma. This lava is so powerful that the light produced by it shoots out with almost star-like luminescence.
While it would travel across the Mid Arm, it would capture wandering inter stellar asteroids, and rogue dwarf planets throughout the 2,000,000,000 BCEs. This lead to its moons, Traditae, being captured on 2,780,140,050 BCE. Incognita, being captured on 2,650,400,219 BCE. Inais, being captured on 2,445,385,009 BCE. Absit, being captured on 2,208,533,150 BCE. Te-Desidero, and Ubies being captured on 9,399 BCE. Solum and its system of moons remained untouched by any Ambrosian civilization, until the Ugnara Kingdom discovered it while radar mapping nearby stars around the capital of the Human Alliance of Ambrosia, the Hope System during the Ugnara Wars in 10465 CE. Once it was discovered the the moon Etiamteamo was habitable, they opted to create a small colony on the moon in order to plan an eventual invasion of the Hope System. However, the Ugnara Wars would end before these plans could come to fruition. After the Ugnara joined the Ambrosia Alliance of United Systems, the Solum System would fall under its governance.
Solum - 1 Oblivio:
Oblivio is the first major moon of the rogue planet Sol um in the Ambrosia Galaxy. It is a scorched tidally locked H-Class world with its surface covered entirely with lava. is a volcanic hell world with a large expanse of lava across the entire landscape, cooler regions of black magma are located on the surface as well. This is because the moon is subjected to immense tidal forces constantly inflicted upon it by its parent planet, creating extreme volcanic activity on the surface. Much like Jupiter's moon Io before it was terraformed, albeit much more potent. This causes the moon's temperature to rise extremely high, and with its thick atmosphere barely any heat escapes and is trapped within itself. The radiation produced by the gas giant also causes this effect. The atmosphere is so thick the moon does not experience any form of night, always existing in a permanent state of day light. This volcanic activity leaves the surface very smooth, the moon has very few mountains. It also has piratically no impact craters with most asteroids incinerate before reaching the surface, if one manages to reach the ground, the crater ls consumed by the shifting landscape.
The moon serves as the "sun" of the Sol um System due to it being the only body in the system that produces natural light, and with the moon being tidally locked with its parent planet, the gas giant is dimly illuminated constantly. This causes the other moons of the system to have a strange day-night cycle, with three standard hours of daylight and three standard hours of night. Thanks to this, it is classified as an: "Astra-Moon" an extremely rare moon class that exhibits these unique characteristics. Before it became the hell world we know today, the moon was a temperate Oceania world with multi-cellular organisms existing within its waters. However, after Sol um's ejection from its home system the moon flew much closer in orbit around its parent planet and it became subject to extreme tidal forces. This evaporated Oblivio's oceans causing a runaway greenhouse effect and covered the surface with thick molten lava. It is also responsible for Etiamteamo surface oceans. The smaller moon orbits in very close proximity to Oblivio, causing its sister moon to keep a warm enough climate for surface liquid.
Oblivio formed along with its parent planet Sol um around 4,127,010,000 BCE. Originally it was a cold ice world, however the moon would be bombarded by dwarf moons in orbit around Sol um, melting the surface and forming a thin oxygen atmosphere. Life began to arise shortly after this event. Around 3,999,666,333 BCE, Sol um would be ejected from its home system and become a rogue planet of the Mid Arm. This caused the ocean moon to be hurled into very close to Sol um. With this, the moon was battered by the gas giant's extreme tidal forces and radiation. This almost instantly evaporated its water causing the moons now thick atmosphere. These tidal forces created extreme volcanic activity across the entirety of the moon, increasing its temperature a thousand fold. With this volcanic activity and increase in temperature, the moon's thick atmosphere began to glow a hellish orange color. This glow was so luminance that it provided sun like light and energy to its sister worlds against the darkness of space. This also provided the moon closest to it, Etiamteamo, with warmth powerful enough to melt its frozen oceans, turning the world to the temperate Terra it once was.
Much like the rest of the Sol um System, Oblivio was unknown to any Ambrosian civilization until the Ugnara discovered it while radar mapping stars around the capital of their enemy, the Hope System during the Ugnara wars in 10465 CE. Once it was discovered, a small fleet of robotic probes were launched to map out the system, discovering the volcanic moon and its sister worlds, including Etiamteamo. With this, the Ugnara would use the Oblvio's home system as a staging ground to launch a surprise invasion on the Human Alliance of Ambrosia's capital star system, Hope. However, the Ugnara were defeated before these plans came to fruition. After the Ugnara's defeat, and eventual joining of the Ambrosia Alliance of United Systems, the Sol um System would be further colonized by the Ugnara as a sort of checkpoint for those who want to enter the Hope System. Small groups of humans would migrate to the system as well. While its sister moon Etiamteamo was majorly focused on, a smaller colony was built in Oblivio's upper atmosphere where the blistering heat is bearable to organic life in 10489 CE. This colony, named Infernium, would continue to grow larger and larger until becoming a functional city with a population of around five million in 10500 CE.
Solum - 2: Etiamteamo
Etiamteamo is the second major moon of the rogue planet Solum in the Ambrosia Galaxy. Its a temperate tidally locked E-Class world. Etiamteamo is a temperate Terra world, its dynamic landscape is covered with mountains, canyons, rivers, lakes, and oceans. It is the only body in the system temperate enough for common organic life to inhabit it without using complex means. This is because the moon orbits in very close proximity to its sister world, Oblivio as it emits constant heat due to its extreme volcanic activity. Etiamteamo doesn't have any native life, however the chemical makeup of its oceans suggests that life is beginning to arise. Because of this, the Ambrosia Alliance puts many protective measures to insure that this up-and-coming life is not contaminated. It is the only body in its home system that has tectonic plates, giving the moon two continents, Tequoqueamo and Amanseteamo respectfully. The moon serves as the capital of the Solum System for these reasons as its the only moon that can naturally support large cites and colonies. So much so that when someone mentions that they are going to visit the Solum System, they usually mean Etiamteamo specifically.
Etiamteamo formed shortly after its parent planet Solum, and its sister moon Oblivio. In its original orbit, it was at a safe distance from its parent gas giant where surface water could be present on the surface. With this, multi cellular life developed on its surface, dense foliage dominated large expanses of the moon for millions of years. However on 3,999,666,333 BCE, Solum would be ejected from its home system and become a rogue planet of the Mid Arm. This caused the moon's oceans to freeze over, turning it into a frozen ice world. After this, Oblivio would be subjected to extreme tidal forces from Solum, causing the moon to emit massive amounts of heat. With this, Etiamteamo would have its surface heated, melting the frozen oceans, turning the world back into a temperate Terra. Though all native life died once the moon was frozen over. Etiamteamo was unknown to any Ambrosian civilization until the Ugnara discovered it while radar mapping stars around the capital of their enemy, the Hope System, during the Ugnara wars in 10465 CE. Once it was discovered, a small fleet of robotic probes were launched to map out the system, after this it was discovered that Etiamteamo was very hospitably. The Ugnara began to construct a small colony on the moon's surface in order to stage an eventual invasion of the Hope System, however these plans fell through after the Ugnara's defeat later in the year. After the Ugnara joined the Ambrosia Alliance of United Systems, Etiamteamo would have towering cites populated by millions of people constructed throughout the 10500 CEs. The moon would also became a very popular tourist destination due to its strange relationship with its sister worlds.
