“ If you looked deeply into a stone, you could see the Light shifting with the chaotic pattern of a blowing storm. It was not calm inside. Not by a wind or a whisper. ”

— Kaladin

Stormlight is a form of gaseous Investiture brought by the highstorms of Roshar.

Origin

by horizonproblems Dalinar bringing the Realms together (and with it, Stormlight)

“ Honor's power, during a storm, is concentrated in one place. It pierces all three realms and brings Physical, Cognitive, and Spiritual together momentarily in one. The gemstones, exposed to the wonder of the Spiritual Realm, are lit by the infinite power there. ”

— Stormfather

Stormlight comes directly from the Spiritual Realm, leaking into the Physical and the Cognitive as the three realms are brought closer together in the highstorm. It's typically brought to Roshar during a highstorm. As it passes, any spheres exposed to it are infused with Stormlight near its end. At the same time, it arrives in Shadesmar as a wave of light on the horizon. There, spren absorb it directly.

In the present, it appears that the Stormfather -- and, by extension, Honor -- is the primary force enabling Stormlight to cross over into other Realms. However, it has existed prior to the Shattering, albeit its properties were slightly different.

Bondsmiths of third Oath or higher can likewise infuse spheres and people with Stormlight, although to do so takes significant effort. Dalinar is also capable of opening Honor's Perpendicularity to release large amounts of Stormlight over vast areas for a limited amount of time, albeit this is unusual, and possibly a consequence of Stormfather's particular nature as Honor's Cognitive Shadow.

Appearance and Properties

Stormlight appears as luminescent white vapor. When free, it behaves similarly to smoke, dissipating in puffs and leaving trails when its source moves. Gemstones left outside during a highstorm absorb it, becoming infused, which manifests as the gems glowing. The amount of Stormlight collected is not directly proportional to the strength of the highstorm.

Absorbed Stormlight, if unusued, will eventually begin leaking out. The speed at which it leaks varies depending on how ideal the vessel is. A person can only hold Stormlight for a few minutes at most, while a gemstone will hold it for several days -- the ones used as currency hold it for about five, while bigger gems last a while longer. Perfect gemstones, like King's Drop, can hold it for centuries, if not forever. When leaking from gems, Stormlight assumes their color.

Uses

Magic fuel

Stormlight is the primary fuel of Surgebinding abilities. To absorb it, a Surgebinder breathes in Stormlight from sources such as gemstones or the highstorm itself. When inhaled, Stormlight gives the user a sensation of increased energy, restlessness and desire to move, with several people comparing it to a storm raging inside them. While held, it will automatically heal wounds, exhaustion and even conditions such as poisoning or drunkenness. It can also be consumed to power the use of Surges.

It can also be used as replacement for other forms of Investiture, most notably Breath. A Returned can survive off Stormlight without the need to consume their Breaths. Likewise, Nightblood can be fuelled by Stormlight, and when unsheathed, will begin to absorb it from its environment before going for living beings. It's possible to transform Stormlight into Breath and use it in Awakening, though that is noted as extremely difficult, with neither Vasher, nor Azure or Hoid having figured out how to achieve this at this moment in time.

Fabrials will not function unless the gems comprising them are infused with Stormlight.

Healing and sustenance

Even for non-Surgebinders, Stormlight has minor healing properties. Thanks to Roshar's atmosphere being suffused with Stormlight most of the time, people living there are notably healthier than non-Rosharans and fall sick less often. Plants can also be encouraged to grow more quickly by placing Stormlight-infused gems nearby. Spren derive sustenance from Stormlight, and it makes them more lively and energetic.

Currency

The gemstones used across Roshar are generally considered more valuable when infused. While nominally spheres have the same value whether dun or glowing, merchants will often find dun spheres suspicious, and can sometimes call an expert to verify if a dun sphere isn't counterfeit. Moneychangers capitalize on this, exchanging dun spheres for infused ones or taking spheres to be infused in their secured nets -- for a fee. The value of infused spheres rises even higher with the return of Surgebinding, with some people making a tidy profit off trading spheres with Urithiru.

Stormlight is directly used as a currency in Roshar's Cognitive Realm, with moneychangers in Celebrant storing it in perfect gemstones. A device is used to transfer stormlight from smaller gemstones into the perfect ones, and in exchange one receives credit which can be spent in the city.
