'''Kylaris''' is a habitable planet in the Solaris system. The world contains many nations, most of which are part of the [[Community of Nations]]. The official languages of the Community of Nations, and by extension of the world of Kylaris, are {{wp|English language|Estmerish}}, {{wp|French language|Gaullican}}, {{wp|Arabic language|Badawiyan}}, {{wp|Chinese language|Songhua}}, {{wp|Indonesian language|Negaran}} and {{wp|Hindi language|Hyndi}}. Tens of thousands of other languages are also spoken. It is home to an estimated 6 billion human beings.
'''Kylaris''', commonly known as '''earth''', is a rocky planet in the Solaris star system. It completes an orbit around Solaris approximately every 365.2422 calendar days (rotations about its axis); from the perspective of its North Pole it, like most celestial bodies in the star system, orbits counterclockwise. It is spherical with a slight bulge at the equator owing to its rotation, which is slightly tilted compared to its orbital axis with respect to the sun, and it has one planetoid moon. Its axis of rotation produces {{wp|seasons}}, as it is titled in respect to the planet's orbital plane. The planet is notable for being the only known location to harbor, at any time, {{wp|life}}.  


Kylaris is currently in a geopolitical situation known as the [[Great Game (Kylaris)|Great Game]], in which the Great Powers battle for influence across the globe. This is largely a result of the [[Great War (Kylaris)|Great War]] 8 decades prior, which changed the face of Kylaris and had a significant impact on the world's socioeconomic and geopolitical status. These great powers are also associated with the geopolitical blocs that they effectively lead. These "blocs" include the [[Euclean Community]], [[Joint Defense Force]], [[Asterian Development Council]] and [[South Coian Defense Initiative]].
The planet is believed to have formed several billion years ago from the heavier elements in the accretion disk of the sun; the presence of these elements mean that Solaris is at youngest a second-generation star. Distinct layers formed over time as accretion slowed and the planet cooled. The planet has a metallic core, which creates a magnetic field around the planet. This is surrounded by a mostly liquid mantle composed of various metallic and nonmetallic elements, silicon being the most common. The outermost layer is the solid crust, or lithosphere, which is thin but encompasses the entire planet. It is composed of generally lighter materials than the mantle. The planet's active tectonics are highly influential on its topography and biosphere.  


The [[Federation of Asteria]], [[Gaullica|Gaullican Republic]], [[Sarenia|Hasemid Empire]], [[Negara|Republic of Negara]] and [[Songguo|Song Empire]] are all considered to be among the Great Powers, and in turn, are players in the Great Game. These powers and blocs have came into conflict with one another on numerous occasions, however most of these encounters - with the notable exception of the [[Southwest Frontier War]], [[Namkwon Emergency]], and [[Third Songhua-Nematsujin War]] - did not contain see the militaries of any of the great powers clash.
The atmosphere is primarily nitrogen with a significant fraction of oxygen; most other components of the atmosphere, including argon and carbon dioxide, are trace. The atmosphere can be divided into layers depending on altitude and is thick enough to burn up the vast majority of objects which fall into it.


Despite this battle for influence, the world as a whole is in an unprecedented era of peace; the Great Powers themselves have not gone to war since the aforementioned conflict over 80 years ago. Human development, quality of life and standard of living is, on the whole, increasing across the globe, and despite the underlying tensions, most conflicts are unlikely to deteriorate to outright warfare. International organisations committed to peace, such as the Community of Nations, provide a forum for the issues between member nations to be addressed in the conference room, rather than on the battlefield.
The majority of Kylaris's surface is uninhabitable. Three-quarters is covered by oceans and other bodies of water. Of the quarter that is land, nearly half is uninhabitable desert, mountains, or ice caps. Only an estimated one-eighth of Kylaris's surface is considered habitable by humans. Although the range of permanent human settlement is limited by geography, modern technology has allowed humans to establish small outposts in even the most challenging environments. [[George_Ruset_Land#Settlements|Suqquirut]] in [[George Ruset Land]] is the northernmost permanent settlement in the world, and the southernmost is the South Pole Station located at the South Pole on the continent of [[Glacia]].
 
All known life is native to the planet, with rough estimates of millions of species and octillions of individual lifeforms. Life is thought to have been present for around half of the planet's existence. The biosphere is believed to be constrained to the crust, the lower atmosphere, and possibly the upper mantle. The only species known to have exited the atmosphere is humans, who are generally considered the dominant species.
 
==Etymology==
[[File:Kylaris blue marbles.png|thumb|right|300px|Two photos of Kylaris from {{wp|Outer space|space}}; the left image shows the continents of [[Euclea]] and [[Coius]], the right image the [[Asterias]].]]
The commonly accepted {{wp|English language|Estmerish}} name for the planet, ''Kylaris'', is a {{wp|Greek language|Piraean}} loanword, from Κυλάρις, ''kylaris''. Kylaris was the name of the Piraean goddess of nature. She was adopted into the [[Religio Solaris|Solarian pantheon]] where she was also known as Terra, resulting in the use of ''terra'' as a name for the planet in {{wp|Latin language|Solarian}} and its {{wp|Romance languages|derivative languages}}.
 
The planet is commonly referred to as ''earth'', another modern Estmerish word, in media and conversation. The word is derived from the {{wp|Old English|Old Swathish}} ''eorðe''. Similar to Kylaris and Terra, Earth was the goddess of the human world in Weranic paganism.
 
==Physical geography==
===Continents and oceans===
Kylaris's surface is customarily divided into five continents—[[Euclea]], [[Coius]], [[Asteria Superior]], [[Asteria Inferior]], and [[Glacia]]—and four oceans: the [[Lumine Ocean]], [[Vehemens Ocean]], [[Boreal Ocean]], and [[Glacial Ocean]]. The continents can be divided into subcontinents that share cultural and geographic affinity. Coius, in particular, is strongly regional, and is usually divided into [[Bahia]], [[Rahelia]], [[Satria]], [[Southeast Coius]], and [[South Coius]].

! Capital
Anatomically modern humans have lived for at least 300,000 years, and human activities have greatly impacted the planet's land and water, atmosphere, and biosphere. Most of these changes have occurred over the last three millennia since the rise of urban civilization and large-scale agriculture, and have greatly accelerated since the Industrial Revolution began approximately 250 years ago.  
! data-sort-type="number" | Population
 
! Continent
Significant human developments include language, of which there are thousands, organized conflict or war (such as the [[Great War (Kylaris)|Great War]], the largest war in history), and techniques for manipulating other species, physical energy, and matter, including electricity, medicine, agriculture, and construction. These technologies have produced tremendous improvements in humanity's quality of life: the human population is currently increasing at an exponential rate as advances have led to dramatic increases in life expectancy. Modern life requires the utilization of an increasing fraction of the planet's natural resources on both per-capita and absolute bases, with total energy use also increasing exponentially.
! Head of State
 
! Government type
Human societies are highly complex and organized. {{wp|Sovereignty|Sovereign}} nations are the basic planetary-scale organizational unit of the human species. Their distribution has a strong relationship to the planet's geological and biological characteristics. These states claim the planet's entire surface area. There has never been a single government with jurisdiction over the entire planet. The closest institution to a world government is the [[Community of Nations]], an {{wp|intergovernmental organization}} created with the goal of preventing armed conflict between nations. It serves as the main forum for international diplomacy and {{wp|international law}}. Dozens of other intergovernmental organizations exist at a global and regional level; these include the [[Euclean Community]], [[Rongzhuo Strategic Protocol Organisation]], [[Asterian Development Council]], and [[Council for Mutual Security and Development|COMSED]].

Kylaris, commonly known as earth, is a rocky planet in the Solaris star system. It completes an orbit around Solaris approximately every 365.2422 calendar days (rotations about its axis); from the perspective of its North Pole it, like most celestial bodies in the star system, orbits counterclockwise. It is spherical with a slight bulge at the equator owing to its rotation, which is slightly tilted compared to its orbital axis with respect to the sun, and it has one planetoid moon. Its axis of rotation produces seasons, as it is titled in respect to the planet's orbital plane. The planet is notable for being the only known location to harbor, at any time, life.

The planet is believed to have formed several billion years ago from the heavier elements in the accretion disk of the sun; the presence of these elements mean that Solaris is at youngest a second-generation star. Distinct layers formed over time as accretion slowed and the planet cooled. The planet has a metallic core, which creates a magnetic field around the planet. This is surrounded by a mostly liquid mantle composed of various metallic and nonmetallic elements, silicon being the most common. The outermost layer is the solid crust, or lithosphere, which is thin but encompasses the entire planet. It is composed of generally lighter materials than the mantle. The planet's active tectonics are highly influential on its topography and biosphere.

The atmosphere is primarily nitrogen with a significant fraction of oxygen; most other components of the atmosphere, including argon and carbon dioxide, are trace. The atmosphere can be divided into layers depending on altitude and is thick enough to burn up the vast majority of objects which fall into it.

The majority of Kylaris's surface is uninhabitable. Three-quarters is covered by oceans and other bodies of water. Of the quarter that is land, nearly half is uninhabitable desert, mountains, or ice caps. Only an estimated one-eighth of Kylaris's surface is considered habitable by humans. Although the range of permanent human settlement is limited by geography, modern technology has allowed humans to establish small outposts in even the most challenging environments. Suqquirut in George Ruset Land is the northernmost permanent settlement in the world, and the southernmost is the South Pole Station located at the South Pole on the continent of Glacia.

All known life is native to the planet, with rough estimates of millions of species and octillions of individual lifeforms. Life is thought to have been present for around half of the planet's existence. The biosphere is believed to be constrained to the crust, the lower atmosphere, and possibly the upper mantle. The only species known to have exited the atmosphere is humans, who are generally considered the dominant species.

Etymology

Two photos of Kylaris from space; the left image shows the continents of Euclea and Coius, the right image the Asterias.

The commonly accepted Estmerish name for the planet, Kylaris, is a Piraean loanword, from Κυλάρις, kylaris. Kylaris was the name of the Piraean goddess of nature. She was adopted into the Solarian pantheon where she was also known as Terra, resulting in the use of terra as a name for the planet in Solarian and its derivative languages.

The planet is commonly referred to as earth, another modern Estmerish word, in media and conversation. The word is derived from the Old Swathish eorðe. Similar to Kylaris and Terra, Earth was the goddess of the human world in Weranic paganism.

Physical geography

Continents and oceans

Kylaris's surface is customarily divided into five continents—Euclea, Coius, Asteria Superior, Asteria Inferior, and Glacia—and four oceans: the Lumine Ocean, Vehemens Ocean, Boreal Ocean, and Glacial Ocean. The continents can be divided into subcontinents that share cultural and geographic affinity. Coius, in particular, is strongly regional, and is usually divided into Bahia, Rahelia, Satria, Southeast Coius, and South Coius.

Human geography

The Community of Nations headquarters in Kesselbourg.

Anatomically modern humans have lived for at least 300,000 years, and human activities have greatly impacted the planet's land and water, atmosphere, and biosphere. Most of these changes have occurred over the last three millennia since the rise of urban civilization and large-scale agriculture, and have greatly accelerated since the Industrial Revolution began approximately 250 years ago.

Significant human developments include language, of which there are thousands, organized conflict or war (such as the Great War, the largest war in history), and techniques for manipulating other species, physical energy, and matter, including electricity, medicine, agriculture, and construction. These technologies have produced tremendous improvements in humanity's quality of life: the human population is currently increasing at an exponential rate as advances have led to dramatic increases in life expectancy. Modern life requires the utilization of an increasing fraction of the planet's natural resources on both per-capita and absolute bases, with total energy use also increasing exponentially.

Human societies are highly complex and organized. Sovereign nations are the basic planetary-scale organizational unit of the human species. Their distribution has a strong relationship to the planet's geological and biological characteristics. These states claim the planet's entire surface area. There has never been a single government with jurisdiction over the entire planet. The closest institution to a world government is the Community of Nations, an intergovernmental organization created with the goal of preventing armed conflict between nations. It serves as the main forum for international diplomacy and international law. Dozens of other intergovernmental organizations exist at a global and regional level; these include the Euclean Community, Rongzhuo Strategic Protocol Organisation, Asterian Development Council, and COMSED.

Human space exploration

Over 350 humans have visited outer space, reaching orbit. The first was Person Mac Person in 19XX. Fifteen people have walked on the Moon. Humans have yet to walk on any other planet in the Solaris system. The only regular human presence in space is on the International Orbital Station.
