Physical & Landscape

Wryn is a planet smaller than Earth with about half of its diameter, at about 7983 km, and a mass 32 per cent of Earth's mass. These properties combined give Wryn a gravitational pull 31 per cent of Earth's gravity both at the equator and the poles; ever so slightly stronger at the poles, though. It's atmosphere is composed mostly of nitrogen and methane, with a small amount of hydrogen. Like the Water cycle on Earth, Wryn experiences the Methane cycle, due to its methane oceans and rivers.

Wryn's landscape consists of rivers, oceans, mountains, valleys and continents. Its continents are small, unlike Earth's which can be several thousand kilometers in length. Underneath the continental crust are several tectonic plates, rearranging themselves over millions of years. These may be responsible for the creation of canyons through hilly plains or these may be ancient dried up river beds.


All life on the planet is silicon-based, a substance that can also serve the same purpose as carbon. It all began as microbes floating in a methane ocean about 5 billion years ago. Over a billion years, the single-celled lifeforms had produced an atmosphere with almost 40 per cent methane. In the coming aeons, methane levels will drop to almost 33 per cent, making the creatures appear smaller with 33 per cent and larger with 40 per cent.

Forests of tall trees almost a mile high scatter across the planet on every continent. The canopy layer is home to the Lehn, small, insect-like creatures that only live within the canopy layer of many of the forests on the planet. At the bottom of the forest, less than 5 per cent of sunlight will reach and thus requires the plant capable of bioluminescent lights called Iolin. Rarely found in the forests are tall, mushroom-like trees with insects leeching on to the nutrients that the tree produces.

Plains on the continents include an alien grass species that occasionally grows to a height of a meter until its top layers are shedded off by the wind to disperse the plant seeds. These seeds are fertilised by an insect called Ulat which leaves behind a trail of a chemical that fertilise the seeds and initiate their growth which last for roughly a month.

Lifeforms within the lake of the Yeenar Crater have colonised the entire lake bed with coral reef-like structures. In the northern side of the lake, hydrothermal vents can be found which is producing the fog of hot methane gas. These hydrothermal vents surround a singular, large vent indicating a magma chamber, capable of erupting as a supervolcano.

Civilisation & Culture

Wrina civilisation has existed for nearly nine thousand years with its ups and downs. Domed cities were built in 8600's for protection from potentially life threatening creatures and diseases. Connecting these cities are hyperspeed railways for transporting goods and materials and passengers, meanwhile, they can enjoy a view of the planet. Inside the cities are skyscrapers with shops and hotel rooms, available for any citizen. The Civilization has recently mostly united into the Collective States of Wryn, a mostly peaceful society.

Wrina usually live in families of five, rarely six or seven and hardly ever more than eight. Almost every Wrina has an extremely long life expectancy of around 400 years, sometimes extending as far as 500 years but this is now considered to becoming more common due to improved lifestyles and health. Usually between 20 and 40 years of age, a Wrina would be starting to raise a family of around four. The gestation period of a Wrina is around 2 months so a family could be completed in less than a year; if they choose to raise four.

Their culture is split into two categories: the Mixar religion (followers) and non-followers. Mixar is a religion believed to be around seven thousand years old, around the birth of civilisation. Any Wrina that believes in the beliefs of Mixar have basically devoted their lives to follow the rules and orders of the religion, but some of these are horrifying, which is why the Mixar population is small. One such instruction is to bathe in the hot methane lake of the northern part of the gigantic Yeenar crater, formed 59 million years ago (a picture is included above this section). This is believed to purify the body in order for them to live again after they die.

The global population on the planet Wryn is currently approaching 14 billion, with a few colonies on their closest moon Nyrne with a total population of 1.5 million, although more colonies are planned and current colonies are to be upgraded. The Wrina are an early Type I civilisation, as measured on the Kardashev Scale. Interstellar travel has technically already begun, with tiny light-sail chips aimed towards the nearest star to the system. Their Traveler 1 and 2 probe swarms, both launched in 9885 have reached around 23000 AU from the two central stars. Plans for a new, manned mission towards one of the closest stars to them has been drawn up and construction could begin within a few decades, but but the enormous amount of money required could push back the planned construction date.
