'''Stormlight''' is a form of gaseous [[Investiture]] brought by the [[Highstorm]]s of [[Roshar]]. It is an integral part of Roshar's ecosystem, and it is used to fuel most of the magic systems found on the planet.

== Properties ==

As a form of Investiture, Stormlight comes from the [[Spiritual Realm]]. It comes into the [[Physical Realm]] through the [[Stormfather]] in Highstorms.{{wob ref|1760}} Of the three possible forms of Investiture, solid, liquid and gas, Stormlight takes on the form of gas, and appears as a luminescent white vapor.{{cite}} Stormlight itself does not make things cold, even though it comes through the Highstorm. However, the process of a gas converting to a solid, such as when a [[Shardblade]] is formed, can cause a change in temperature and condensation.{{wob ref|1573}}

Stormlight can be collected and stored in different things, the most common being Gemstones. The most common way to collect Stormlight in a Gemstone is to leave it outside during a Highstorm.{{book ref|sa1|11}} The amount of Stormlight collected is not directly proportional to the strength of the Highstorm.{{wob ref|11482}} The amount of Stormlight a Gemstone can hold is directly proportional to the size of the Gemstone.{{cite}} While Gemstones are fairly good containers for Stormlight, the cut and flaws in the Gemstone make it so Stormlight will leak out of the stone over time.{{wob ref|10415}} However, perfectly cut Gemstones can be perfect containers and seemingly hold Stormlight indefinitely.{{cite}}

A person can also collect and store Stormlight in their body, although not inherently. The person must have gained access to a magic system, such as through the Nahel Bond, to be able to store and use Stormlight directly.{{cite}} The most common process for drawing Stormlight into the body is through physically and/or mentally{{wob ref|2533}} breathing it in. However, not everyone experiences this process exactly the same.{{cite}} 37? The body is a very imperfect container for Stormlight and consequentially Stormlight will leak from the body much faster than a Gemstone{{cite}} through the skin, the eyes, and the mouth. Someone holding Stormlight can hold it longer by holding their breath.{{cite}} Difference races have bodies that are more efficient at holding Stormlight that other races. For example, Voidbringers are more efficient than Humans.{{cite}}(from books){{wob ref|63}}

Stormlight is an integral and essential part of Roshar's ecosystem, and as such its nature causes it to leave most any container, unlike [[Breath]] on [[Nalthis]] which is naturally sticky.{{wob ref|63}} As Stormlight is used, the amount in the container holding it will be depleted and it is used-up.{{cite}} However it is a renewable resource and will regenerate in the Spiritual Realm to start the process all over.{{wob ref|4266}}{{wob ref|11041}}

Stormlight can pass through solid matter, but only if it is not overly thick, which allow it to pass through the glass that holds Gemstones, or thin stone of the outer wall of a building in a Highstorm to infuse the Gemstones.{{wob ref|3303}} Stormlight can not pass through Aluminum.{{wob ref|8169}}

Stormlight is naturally luminescent and gives off light even when contained in Gemstones. Stormlight also generates light when held in a person, which can cause the person to have the appearance of glowing, most readily visible when not in direct sunlight.{{book ref|sa3|59}} However, it is the Stormlight that is glowing, not the skin of the person.{{wob ref|3780}} If the person holding the Stormlight sucks in their breath and holds it, they can reduce the glowing effect.{{book ref|sa3|25}}

== Uses ==
As Stormlight is a form of Investiture, it is used to power the magic systems found on Roshar. The current most common use is to fuel the operation of [[Fabrial]]s where a Stormlight infused Gemstone powers the function of the Fabrial. Stormlight is also used by Shardplates, which are not actually Fabrials but are considered as such in-world.{{cite}} Unlike normal Fabrials, Shardplate consumes Stormlight when it is being repaired or regrown, but then does not require any further Stormlight for it's normal operation.{{cite}} However, if Shardplate is damaged, Stormlight can be seen streaming from the cracks and breaks in the Shardplate.{{cite}}

Stormlight also fuels all [[Surgebinder|Surgebinding]] abilities. The exact method and use of the Stormlight can vary by Surges, and different Surges consume different amounts of Stormlight. Surgebinding requires the Surgebinder to directly hold the Stormlight, but the process of drawing it from a source like a Gemstone and applying it to the Surge can be nearly instantaneous.

In addition to the Surges that are part of Surgebinding, anyone with a Nehal Bond gains a dramatic healing ability fueled by Stormlight. In the process, Stormlight repairs and aligns the body with the spirit, and can even heal damage done by Shardblade.{{cite}} However, this healing process also goes through a filter of how the individual views themselves, which can limit what gets healed in the body.{{wob ref|1009}}{{wob ref|5639}}.

Stormlight also fuels the process of the [[Parshendi]] converting their Form. This conversion requires a specific type of spren, one for each Form type, and significant amounts of Stormlight as can be found in a Highstorm. (Must it be in a high storm?) Once the conversion has taken place, the Parshendi maintains its new Form with all of its abilities, without any further Stormlight consumption.

Because of the luminescent nature of Stormlight when contained in Gemstones, infused Gemstones are commonly used as a light source on Roshar, much more convenient than fire. Most people carry a few gems with them at all times to use for light. As a result, Stormlight itself is a currency on Roshar, with infused Gemstones being more valuable that dun ones.{{cite}} This becomes more so when [[Urithiru]] is occupied and the need for Stormlight increases, especially when the Highstorm cycle is interrupted by the Everstorm and infused Gemstones become more rare.{{cite}}

Stormlight is also a currency in the [[Cognitive Realm]] of Roshar, with moneychangers in [[Celebrant]] storing it in perfect Gemstones which never go dun.{{book ref|sa3|97}}{{book ref|sa3|99}} A device is used to transfer Stormlight from smaller gemstones into the perfect gemstones, and in exchange one receives credit which can be spent in the city.{{book ref|sa3|99}}

== Effects ==
A Surgebinder that draws in Stormlight immediately experiences a veriety of effects and benefits:
* Granted extra strength, speed, and endurance{{book ref|sa3|29}}(the section where they are doing tests)
* Can reduce the effects of cold.{{book ref|sa3|8}}
* Can reduce the need to breath{{book ref|sa3|63}}. 
* Can make someone sober.{{book ref|sa3|18}}
* Can prevent fatigue.{{book ref|sa3|39}}
* Causes the holder to feel energized, with a need to be active.{{book ref|sa3|10}}

A Surgebinder that has drawn and used large amounts of Stormlight can be left feeling drained and exhausted.{{book ref|sa3|59}} However, there are no toxic levels of Stormlight.{{wob ref|8627}} Continued use of Stormlight will have permanent effects on the body, the most obvious being eye color from dark to light.{{cite}} While there are extreme cases of changes to the bodies of those that use [[Soulcaster]] Fabrials, for example the Soulcaster [[Kaza]] became disfigured with parts of her body turning to smoke,{{book ref|sa3|i|4}} those changes are caused by the magic systems rather than Stormlight itself.{{wob ref|8627}}

In addition to effects on the bodies of those using Stormlight, it can have a large impact on the flora and fauna of Roshar. Stormlight helps extremely large animals with [[Gemheart]]s to not be crushed under their own weight{{cite}}, allow others to fly{{cite}} and can possibly increase the rate at which plants grow.{{book ref|sa3|i|5}}

== Additional Information ==
* The additional strength that comes from Stormlight does not match the level of strength that comes from wearing Shardplate.{{wob ref|9234}}{{book ref|sa3|120}}
* A form of stormlight existed before Honor came to Roshar. {{wob ref|9266}}{{wob ref|2549}}
* Stormlight in use by one person resists being taken in and used by another person. {{book ref|sa3|61}}(other)
* Stormlight can be used to power other magic systems{{wob ref|6861}}
