Overan

Overan or RSC 1237-99-4-509-48 4 - is the fourth planet from the star RSC 1237-99-4-509-48(White dwarf). The planet is a cool/temperate marine superferria with life. Overan is very ancient and is located only 1.03 light years from the central supermassive black hole of the Triangulum galaxy. This planet is believed to be as old as the galaxy.

==History==
*~12.8 billion years ago. Overan formed 12,870 million years ago, at the very beginning of the birth of the galaxy.
*~12.7 billion years ago. The planet cooled quite quickly and at that time the first oceans already existed
*~12.4 billion years ago. The emergence of unicellular life in cold oceans.
*~10.1 billion years ago. Multicellular life emerged
*~9 billion years ago. Complex organisms ventured onto land for the first time.
*~8.8 billion years ago. A hypernova explosion close to a star system. The event was very destructive, and about 90-95% of the flora and fauna on Overan died. After this disaster, life was able to adapt to such devastating events and thrive.
*~8.6 billion years ago. Presumably the age of the giant structure.
*~7.5 billion years ago. Mass extinction due to gamma ray burst. The planet's ozone layer has weakened significantly, more than half of the biosphere has died.
*~4.8 billion years ago. The beginning of a very long ice age. Probably the entire planet from space was visible as a large snowball. This ice age lasted 1.2 billion years. The temperature was below -70 °C.
*~3.6 billion years ago. Unexpected and rapid warming of the planet. The biosphere was not prepared for such rapid climate change, and most species became extinct.
*~900 million years ago. The fall of a large asteroid-satellite with a diameter of 10-15 kilometers. The strangest thing is that the mass extinction caused by the fall did not occur throughout the planet, but only near the site of the disaster.
*Today - Overan has a long history. The planet has several seas. The atmosphere is dominated by oxygen with an astonishing 71%. There is little nitrogen in the atmosphere, which is not very good. CO2 has 5% in the atmosphere, which is quite a lot, and given the low volcanic activity, it can be assumed that this is the result of the actions of an alien civilization. Overan has increased background radiation. The temperature spread is large. The climate is reminiscent of tundra and taiga (boreal forests). Forests and vegetation cover large areas. Overan can also be called a high-mountain world, because different mountain ranges are spread across the planet. There are no volcanoes on the planet.
==Biosphere==
The biosphere is not very diverse. Animals on Overan are very well adapted to low temperatures. They are quadrupedal and have a very thick camouflage coat. Their internal structure is complex and proves the very long evolution of life on this planet. Often animals appear with vestigiality. Flying species are not common and fly very low. The insects are quite large and look like fat pink bumblebees. These insects are not aggressive and at most they can try to scare you with their size and numbers. Terrestrial fauna are adapted to sudden changes in temperature, so they can easily survive in different conditions. Also, thanks to the very large amount of oxygen, animals can stay awake for a long time, which is useful for survival, given the long solar day. The flora is green and covers a significant amount of land. Low-growing coniferous forests are common. Low green grass covers almost the entire planet, with the exception of some areas. Just like on Earth, there are flowers on Overan. Marine life is adapted to very low temperatures and extreme conditions. Surprisingly, the marine fauna and flora seem to have changed little after the Ice Age, and fossils are almost identical to modern species. At the bottom of the ocean, temperatures are too low and there is almost no life there, with the exception of extremophiles who live near geothermal sources.
==Ancient structure==
When approaching the planet, the first explorers saw a very tall and huge black structure in the distance. At first they thought that they were just imagining it, until they approached this majestic structure. This structure is the most amazing thing we've seen so far. The exact age is unknown, but radioisotope dating puts the age at 8.6 billion years ago, or 5.2 billion years after the Big Bang. The analysis has been criticized, but if the results are correct, then we are faced with what may be one of the first civilizations in the universe. The material from which the structure is created is unknown to modern science. The height of the structure is about 20 kilometers. Excavations carried out at the foot of the building showed that the structure also has an underground part. Most likely, over billions of years the structure slowly sank underground. The purpose of this huge and majestic structure is unknown. Some scientists suggest that this is some kind of radar or radio repeater. The most amazing thing is that the civilization that built this must be very advanced and be able to move between galaxies. Similar but smaller structures have been discovered on various planets with life, including Niaria. The most important mystery for scientists is that the age of structures on each planet is different. Does this mean that the civilization that built the great structure on Overan has existed for billions of years? How? If not, then who built it? One thing is clear for sure - Overan holds many mysteries that we still have to solve. But... The mystery begins to clear up.

==Star system==
Overan orbits a cool white dwarf that was once a completely different star. The white dwarf RSC 1237-99-4-509-48 is orbited by 7 planets. Overan is the only planet with liquid in this star system. But there are a couple of interesting objects. RSC 1237-99-4-509-48 3.1 - warm arid subterra. More than 10 billion years ago, this moon had water and seas with huge rivers, but unfortunately, a collision with a large asteroid completely evaporated the oceans and possibly destroyed the life that was there. RSC 1237-99-4-509-48 5 - cold megajupiter with life. This amazing cold gas giant with a mass of 12.786 M♃ has a developed biosphere in the upper layers of its atmosphere. Most likely, life appeared there due to organisms from Overan, which, thanks to the asteroid, were able to get to the gas giant. The temperature is -100/-120 °C (173-153 K), but life on this planet is adapted to this. This rich natural world is amazing with its huge soaring herds and forests that are difficult to describe in our human language. Many explorers who visited this planet reported the melancholy and calm they felt in these beautiful white and bluish clouds.
