Pyreen is small, with only a diameter of 7263.187 kilometers (56.938 percent that of Earth). Gravity at the equator is 0.23393 g's, while gravity at the poles is 0.234 g's. A day on Pyreen lasts 5.068 Earth days, and a year is 7.266 Earth years.
Pyreen maintains a highly circular orbit 3.729 AU from it's parent star, Nortesx A. The tilt of the planet is 167 degrees, and the temperature has a mean of -133 degrees Fahrenheit or -91.6667 degrees Celsius. The ESI of Pyreen is calculated to be 0.527.
In 4251, colonists noticed a slight increase in radio noise about three-fourths into the journey. Further investigations led to the discovery of the Nortesx system, a binary system consisting of two yellow and orange dwarf stars. Scientists were among the first to enter the system, but what they found was that the signals originated from two sources: a planet orbiting the yellow dwarf (Nortesx A) and another planet orbiting the orange dwarf (Nortesx B). Their first target was Pyreen, whom had the strongest signal of the two sources.
Life was quickly discovered, as there were no oceans or lakes to be seen from orbit and yet a thick, purple flora covered the surface. The native life formed here are short, thick brush with high photosynthetic rates due to the weaker sunlight received from the parent star. These plants are akin to the purple sage on Earth, and often grow to about fifty to ninety centimeters in height. Reproduction is conducted by seedling "plumes," a final act by a dying plant that spreads thousands of seeds anywhere between a few hundred meters or several kilometers due to winds. This highly effective method of spreading genetic material is has led to the quick cover of the Pyreen. After taking flight, soft sand allows seeds to easily bury themselves, and vitamins within the seed provide the nutrients required to break through the ground and begin benefiting from sunlight. These plants contain mostly fluids, and just pinch of salt can kill them. This is why the largest salt flat on Pyreen, Marlow Flat, remains a desolate wasteland; any plants that grow here have all their moisture absorbed, killing them from dehydration.
A manned landing made contact with the Carens, a growing civilization on the surface of Pyreen. Their weak infrastructure was only found within the lowest parts of Marlow Flat. Since their homeworld Daylie had a much thicker atmosphere, the Carens wanted to locate themselves where the atmosphere was thickest. However, it was found this would also be their biggest challenge, since even with genetic alterations that allowed them to breathe in a thinner atmosphere the vast majority of the surface of Pyreen contained too little air for outdoor expeditions. Also, large equipment is what helps maintain health among the colony in the low gravity. This equipment appears to be immobile, further making exploration of Pyreen impossible for the Carens. So, they thrive in low orbit of the planet. While the colony is small, it mainly consts of a space port where shuttles departed and landed. However, this was not the source of the signals. Instead, is was a massive orbital habitat. This megastructure was measured three-fourths of a kilometer in length and five-hundred meters in width. While the exact population remains unknown, it is estimated to be a couple thousand.
Due to the nature of deserts, the landscape of Pyreen is more uniform than most planets.
The majority of Pyreen are rolling hills and is also where plantlife flourishes. These areas can linger usually between one and two kilometers above "sea level."
Also common are mountains. Mountains appear in patches or small ranges. While almost all mountains extend ten kilometers above "sea level," a few regions of Pyreen are home to white-capped mountains. The largest of these patches is around a thousand kilometers wide and consists of a dozen or so mountains. Since these mountains appear in the middle of flat plains, they can be seen anywhere across the planet.
Many salt flats exist on Pyreen, but many with the exception of Marlow Flat are small. These flats are only a few meters above "sea level" and are extremely level.
