Editing Rosharan system

== The Sun ==

The centre of the system is situated a large sun around which all of the planets orbit.{{wob ref|7966}} Though it is smaller than [[UTol system|UTol's sun]].{{book ref|yumi|35}}

The Greater Roshar system is composed of three terrestrial planets and ten gas giants, divided by the asteroid belt. From the sun, the planets in the system are:

=== Ashyn ===

'''[[Ashyn]]''' is the closest planet to the Rosharan system's sun.

While there are humans inhabiting this planet, a global cataclysm at some point in the past has forced most of its inhabitants to flee to Roshar, while the remainder lives in floating cities in the sky and in small areas of habitability.{{au ref|roshar}}{{book ref|tsm|2}}{{wob ref|9847}} The cataclysm was likely caused by overuse of [[Surge]]s by Ashynites, and has left the surface highly volcanically active. There is a known manifestation of Investiture on Ashyn, based around Surge-granting diseases, but no known Shard.{{wob ref|6646}} In Rosharan mythology, Ashyn is referred to as the [[Tranquiline Halls]].{{book ref|row|17}}

Ashyn has a notable axial tilt, allowing it to experience seasonal variation.{{wob ref|11448}}

It is visible in the sky from Roshar.{{book ref|sa4|80}}

=== Roshar ===

'''[[Roshar]]''' is the second planet is the eponymous planet of Greater Roshar. The [[Shard]]s of [[Honor]] and [[Cultivation]] can be found here. Roshar features a single supercontinent, also called Roshar, on which its inhabitants live. Its semi-major axis is such that it has an orbital period of approximately 1.1 years.{{wob ref|8928}}{{wob ref|3781}}{{wob ref|5569}}{{wob ref|10572}}

Roshar has a surface gravity or approximately 0.7g, and a radius of approximately 5663 kilometres, just under 0.9 cosmere standard.{{au ref|roshar}}{{wob ref|10231}} The planet has a substantial atmosphere, and has a partial pressure of oxygen that is higher than standard cosmere.{{au ref|roshar}}{{wob ref|1806}}

Roshar has no axial tilt.{{wob ref|11448}} It has a solar day of twenty Rosharan hours, and rotates around five-hundred times every orbit.{{wob ref|248}}

Three moons, [[Roshar#Planetary System|Salas, Nomon, and Mishim]], orbit the planet in unstable, highly eccentric orbits.{{map ref|Roshar system}}{{wob ref|8096}}{{wob ref|12702}}

The majority of the Rosharan System's sentient lifeforms lives on Roshar.

=== Braize ===

'''[[Braize]]''' is the third planet from the Rosharn system's sun.{{book ref|sa4|80}}{{map ref|Roshar system}} It is a cold planet, perhaps outside the habitable zone. While no humans live here, there do exist self-aware Splinters that inhabit either the planet or its Cognitive manifestation.{{au ref|Roshar}} Braize is where the Shard of [[Odium]] resides.{{wob ref|9847}} In Rosharan mythology, Braize is referred to as [[Damnation]], and is where Rosharan Heralds returned to between [[Desolation]]s.{{book ref|sa3|121}}

The land is cold, barren, and inhospitable to all biological life;{{book ref|sa4|80}} it is constantly swept by winds.{{book ref|sa4|80}} Its atmosphere is much thinner than Roshar's.{{book ref|sa4|80}}

Like Ashyn, it is visible in the sky from Roshar.{{book ref|sa4|80}}

=== Gas Giants ===

Beyond the asteroid belt are ten gas giants. These outer planets, which are designated by [[Ten Essences|Vorin numerals]], are '''Jes''', '''Nan''', '''Chach''', '''Vev''', '''Palah''', '''Shash''', '''Betab''', '''Kak''', '''Tanat''', and '''Ishi''', in order of increasing distance from the sun.

The existence of ten of these, and the relation it has to the importance of 10 to Honor and the Rosharan System, is currently unknown.{{wob ref|2745}}{{wob ref|14144}}

The Rosharan gas giants have a minor presence on Shadesmar, which indicates that they are uninhabited.{{au ref|roshar}}{{wob ref|1540}}{{wob ref|2262}} None of these planets have known moons or ring systems.{{map ref|Roshar system}}{{wob ref|13014}}

The Rosharan system was created prior to the [[Shattering]], and was crafted directly by Adonalsium about 12 to 13 thousand years before the True Desolation.{{epigraph ref|sa2|66}}{{wob ref|9283}}{{wob ref|14898}}{{ref|group=fn|text=Whether this refers to standard years or Rosharan years is currently unclear.}}

After the Shattering, the Shards Honor and Cultivation settled on Roshar, becoming the gods of Singer people. Humans initially settled on Ashyn, but following the destruction of its environment around 7000 Rosharan years before the True Desolation,{{book ref|sa4|14}}{{book ref|sa4|111}} migrated to Roshar, and were granted the land that comprises modern [[Shinovar]]. The Shard Odium arrived on Roshar alongside them, and while the Singers believe it to be the human god, the exact relation is unclear.{{book ref|sa3|111}}

Honor trapped Odium in the system by unknown means, and the shard settled on Braize. However, when the relationship between humans and Singers deteriorated to the point of war, Odium took the Singers under his wing, creating the first Fused and starting the cycle of Desolations, periodic invasions of Roshar.{{book ref|sa1|part=prelude}} During that time, Honor was killed by Odium, but his pact with Odium, along with the [[Oathpact]] that governs the Desolations, prevented Odium from leaving the system.{{book ref|sa3|57}}

For over 4500 Rosharan years since Aharietiam,{{book ref|sa1|prologue}} the Rosharan system has enjoyed a period of relative stability, although this ended with the start of the [[True Desolation]].
