Izanagi

Izanagi, named after the creator of life in Japanese mythology, is a planet located 201 light-years from Earth. It is located in the constellation of Centaurus, and orbits a binary pair of orange dwarf stars, named Monimos A and B, which are too dim to be seen with the naked eye. The planet was discovered on May 15th, 2023, by the JWST, while observing a period of dimming in its stars light which happened almost every 230 days. It is one of 5 planets orbiting the pair of stars. It was the first planet discovered by Humanity that was confirmed habitable, and only years later, it was discovered that an intelligent species was inhabiting its surface. The world was given an ESI rating of 0.893, or 89% similar to earth.

## Discovery & Planet Information

Izanagi is classified as a super-earth exoplanet; it is 1.2 times larger than Earth and has 1.5 times the gravity of our planet. Izanagi has an atmosphere similar in composition to ours, having slightly higher carbon dioxide and water vapor levels than our atmosphere, along with similar atmospheric pressure, only being around 1.5 times denser than ours. Upon initial discovery, the planet was thought to be a mini-Neptune, due to scientists being able to determine the composition of the planet. Further studies concluded that the planet was indeed rocky, due to its small size, and no detection of hydrogen or helium present in the atmosphere. Before Izanagi was given its proper name, the planet was initially given the catalog name of JSW-554-46 e. It wasn't until August 22nd, 2032, that a major discovery was made, being the detection of large amounts of oxygen in the planet's atmosphere discovered by the Starshade telescope shade, which was launched in 2025 to be used along with JWST to further analyze the atmospheres of exoplanets and photograph them. this discovery immediately shocked the scientific community, due to oxygen being a biproduct of life. the planet was then designed to one of the most potentially habitable planets discovered, and work started immediately to learn more about the planet.

## History

* -7.2 Billion years ago: Izanagi is a protoplanet along with many other protoplanets and young planets forming around the twin stars.
* -7 Billion years ago: Izanagi is struck by a planet only slightly smaller than it, which flips Izanagi's axis and forms two moons.
* -6.4 Billion years ago: the planet cools down to an average surface temperature of approximately -13 °C.
* -6 Billion years ago: Izanagi is bombard with asteroids and comets, containing large concentrations of water and salt.
* -5.4 Billion years ago: Izanagi's atmosphere forms, and water vapor rains down in large global storms, creating vast lakes and oceans.
* -4.1 Billion years ago: The first Unicellular organisms emerge in the oceans of Izanagi
* -3.3 Billion years ago: First Multicellular organisms, and the atmosphere is filled with oxygen due to the plankton in the oceans.
* -3.1 Billion years ago: First plants on the land of the planet, the soil becomes fertile and rich with Nitrogen
* -2.3 Billion years ago: The planet heats up to an average surface temperature of 18 °C.
* -1.2 billion years ago: First animals on Izanagi
* -600 Million years ago: Mass extinction caused by one of the stars' solar flares, killing 98% of all species.
* -450 Million years ago: Surface of Izanagi heats up to average temperature of 19 °C (the normal temperature to this day).
* -48 Million years ago: Planet is struck by a 31km Asteroid, killing 89% of all life.
* -1.2 Million years ago: Izanagi is now covered in lush forests and vast plains and teeming with life.
* -280,000 years ago: Earliest ancestors of the Izana.
* -51,000 years ago: The Izana migrate around the planet, inhabiting most areas.
* -9,000 years ago: earliest evidence of language and writing
* -1,200 years ago: First Izananian societies rise, and some wars break out over land disputation.
* -200 years ago: First humans arrive at Izanagi, after receiving an SOS encoded message from deep space.
* TODAY: Humans and the Izana live together, exchanging culture and helping one another, in a great interspecies relationship

## Discovery of the Izana Civilization

On October 16th, 2048, a signal was detected by the CETI from within the constellation of Centaurus. It wasn't like any signal scientists had ever picked up from deep space. It was a series of medium pitched frequencies that followed 3 short frequencies, 3 long frequencies and another 3 short ones. The signal repeated for over 3 minutes and 36 seconds before cutting off. The signal was picked up at slightly above the protected 1420Mhz. About an hour after the signal was picked up, concerns rose that the origin of the signal was of technological origin, after being determined the signal came from a star system 200 light years away. At the time this star system was catalogued as JSW-554-46 and after closer inspection, was determined to have come from one of the planets orbiting the pair of stars, specifically JSW-554-46 e. frantically searching for answers, only a year after the signals detection, a discovery was published that shocked the world. It was an SOS signal encoded in morse code. On the day of November 21st, 2049, extraterrestrial intelligence had been confirmed, humanity was not alone. A global holiday was created, known as "Contact Day", along with a signal being transmitted back to the planet of origin. This discovery marked a new era for humanity, most drama in the world came to a stop, with a new focus of somehow getting to this planet, due to the signal being an SOS signal. Focus shifted, it was now a race to see who could find out a way to travel to this star system and help whatever was crying for help. Companys began construction of orbital vehicle assembly factories and began to try and experiment on the rockets they used to transport people between earth and mars. Reaching this planet was no easy task, but humanity was worried that it would be too late if they waited too long. It took only 50 years to design a propulsion system which could move matter faster than the speed of light, meaning it could get from Earth to Izanagi in just around 20 years. After 5 years of trials and tests on the system, it was given approval by the FDA of using it with human passengers for the first time, and finally on June 9th, 2104, the first manned mission to Izanagi was launched, the ship used was named "Destiny 1" carrying over 1000 human passengers and lots more cargo, left earth on a voyage to reach Izanagi. Using the new method of propulsion in mind, a ship was constructed with an elongated body, using fusion thrusters to allow the ship to accelerate, along with the new acceleration drive. The vessel also had over 1000 cryopods for human passengers, and a massive mirror towards the front end of the ship, to block any interstellar dust during travel. The ship was capable of accelerating to over 15 times the speed of light, allowing for very fast travel between star systems. The ship takes 1 year to accelerate to its cruising speed, where it then flips around 180 degrees, and uses its mirror to deflect interstellar dust, and 1 year to decelerate to orbital speeds. Humans are put into cryosleep, with crews rotating every few years to keep systems online and safe.

## First Contact

During Destiny 1's deceleration period, signals were sent to the planet of Izanagi, in hopes of a response, that the civilization would still be alive. 4 total attempts were made to contact them, and during the 1-year deceleration period, a response was given from the Izana. Although the language could not be translated, it was definitely a great sign that the Civilization was still there, and humans would soon attempt to "properly introduce themselves" to the aliens. The destiny ship soon arrived into orbit around the planet, where it sent two probes to the planet's moons, Agni and Indra. Curious aliens launched rockets to intercept Destiny 1, humans did not perceive this as a threat, but did attempt to warn the native species they did not want any trouble. Probes and small robots were sent to the surface of the planet, to calculate the atmosphere's density and to figure out its true composition and breathability, as well to attempt to communicate humanities intentions with the Natives. After 3 days in orbit, humans learned from transmitted data by the aliens that they called themselves the "Izana" and welcomed humans to explore their surface, and to meet each other. By then, humanity had advanced language translation systems, so it was not long before humans and Izana could communicate with each enough to understand both their intentions. Small craft that were attached to 4 docking stations along Destiny 1's exterior carrying human scientists detached and descended into the newly named Izanagi's atmosphere. The human crafts landed in unison near an Izanian city, allowing them to secure the area, where Humans and the Izana met for the very first time. It was a day in human and Izana history, which sparked a new era for both civilizations.
