“Spren appear when something changes—when fear appears, or when it begins to rain. They are the heart of change, and therefore the heart of all things. ”

— Hesina to Kaladin

Spren are fragments of the powers of creation that have since then gained sentience through the influence of sapient beings on Roshar. They are vastly varied in their appearances, characteristics, and levels of intelligence. They are deeply connected with the Knights Radiant, as a Nahel Bond between humans and spren are what allows the former to use Surgebinding. They are also used to create fabrials.

Some spren predate the arrival of Honor and Cultivation to Roshar, and perhaps even the Shattering. These are Splinters of Adonalsium itself that it left behind intentionally and that have attained sentience on their own since then. All spren dwell mostly in the Cognitive Realm, as it is there that the powers of creation come alive, shaped and given cognizance by the ideas and concepts of the collective experience of sentient creatures. Over time, those ideas and concepts become personified as an external entity, becoming spren.

Spren are far more extensive and numerous than the closest comparable entities, seons and skaze, Splinters of Devotion and Dominion respectively. This is one of the reasons Roshar does not have the same problem with travelling to the Cognitive Realm as Sel, even though Honor is Splintered just like the other two Shards. On Roshar, spren act as a "release valve" for the uncontrolled power of Honor.

Characteristics

“ We don’t sleep; we don’t eat. I think we might feed off humans, actually. Your emotions. Or you thinking about us, maybe. It all seems very complicated. In Shadesmar, we can think on our own, but if we go to your realm, we need a human bond. Otherwise, we’re practically as mindless as those gloryspren. ”

— Sylphrena on the nature of spren

For Rosharans, the term "spren" has broad application. Entities such as Shards, Cognitive Shadows and other beings from beyond the Physical Realm would be considered spren by the Rosharans. Among those are Cognitive aspects of objects. Those Cognitive aspects are based on how they are viewed by the surrounding entities and how long they've been the way they currently are. These "spren" can be spoken to in the Cognitive Realm and bribed with Stormlight, which forms the basis of Soulcasting. In Shadesmar, they usually take the form of small beads, akin to spheres that serve as Roshar's currency. A skilled person can "manifest" a bead, making it take the form of its Physical counterpart.

In the strictest sense, however, spren are splinters of one of more Shards, with a single spren being composed of one or more types of Investiture. Most spren are splinters of Honor and Cultivation, or a mixture of both that leans towards either one Shard or the other. There are said to be thousands of different kinds of spren, each named for a different type of phenomenon. They vary vastly in size, with the smallest being the size of a thumbnail, while the largest can dwarf buildings.

Larger spren have the ability to shape-shift, often mimicking faces, as well as being able to mimic voices. They also have the ability to pick up small objects and give small pinches of energy. They will often appear to a singular person, who they will taunt and play with. Some humans, such as Rock, have the ability to see these spren, even if the spren in question does not explicitly reveal itself to the viewer. These people are called alaii'iku by the Unkalaki.

Spren are generally personification of certain cognitive ideals and concepts. These cognitive ideals are similar to those that determine the appearances of the Returned on Nalthis and the plausibility of Forgeries on Sel, and are based off of human perception. Spren are also related to the physical phenomena of wave-function collapse -- one can fix a spren's dimensions simply by the act of measuring it. The causal link between spren and their namesake is not fully understood on Roshar. Some spren, such as rotspren, are said to cause their namesake, whereas others, such as windspren, are merely attracted to it.

Spren do not need to sleep, but they can die. In Shadesmar, they appear to feed off Stormlight, growing more lively and energetic when one passes over them. Among their vast variety, several main types can be discerned.

Several types of lesser spren, as seen in Shadesmar

Lesser Spren

Vast majority of all spren is non-sapient. Although some can speak, talking with them is generally an exercise in futility, which leads to people ignoring them a lot of the time. Spren of the same sub-type are essentially the same individual, with no differences between any two entities. They are capable of forming a bond with humans, though it is different from the Nahel bond of true spren. As creatures of nature, spren are not particularly concerned with good and evil.

Lesser spren vary in how much they appear in the Physical Realm. Some, like windspren, exist almost entirely in the Physical, having next to no imprint on Shadesmar. By contrast, others exist mostly in Shadesmar, with only parts of them, like tongues or drool, visible in the Physical. There are also spren like mandras (luckspren), who will often and easily switch between existing in the Cognitive and the Physical. In Shadesmar, this phenomenon is called "dropping", as the spren appears to drop out of existence, and then drop back in.

Nature and emotion spren

Lesser spren are divided into nature spren and emotion spren. Emotion spren are attracted to sensations like anger, joy or passion; they are composed of more Honor than Cultivation. Nature spren are attracted to natural phenomena like wind, decay or rain, and have more Cultivation than Honor in them. Emotion spren will react to emotional Allomancy.

While the lesser spren are often invisible, they are said to be ever present and will pop up around the phenomenon they are named for. This is with the exception of Shinovar, where spren rarely appear. Some spren are easier to find than others, though even the most common will, at times, fail to appear.

Odium's influence

Lesser spren can be corrupted by Sja-Anat, a process which she refers to as "enlightening". Such corrupted spren will appear to be misshapen compared to their regular counterparts, with various parts of them exaggerated to a more painful degree -- for example, a hand becoming more wiry and bony, or petals turning into shards of glass.

Separately, there exist voidspren, spren made up of the essence of Odium. The lesser voidspren are, like their native Rosharan counterparts, non-sentient. They can, however, form bonds with singers, granting them Regal forms, which often include supernatural powers and a change in mindset in the singer.

True Spren

Spren that do possess sapience are referred to as true spren. They seem to all represent higher concepts, such as honor for honorspren and truth and lies for Cryptics. Nine types of true spren bond with humans to grant them Nahel Bonds and thus, the power of Surgebinding; however, more types of sapient spren exist.

While true spren can transition into the Physical Realm, they do so rarely, and only when seeking to bond a prospective Knight Radiant. This is because transition between the Realms leaves holes in their memories and impairs their cognitive functions in some ways. Even after forming a bond, moving too far from their bonded Surgebinder will cause the spren's mental capacity to degrade once more.

Once the true spren make the transition, they cannot affect the Physical Realm in any but the most minor ways. While in Shadesmar, most sapient spren have a humanoid shape and size, in the Physical Realm they usually take on a smaller and simpler form.

In Shadesmar, true spren have their own culture, politics and nations; though the Cognitive Realm was created by creatures of the Physical, it is spren who shape and rule it. Some spren, like Cryptics or highspren, have nation-states, composed wholly of spren of their own kind; others, like honorspren, seem to rule a nation of their own, but also allow other types of true spren to live with them. There are also city-states such as Celebrant, where various spren live together.

by Bonnie Johnson Glys, a corrupted Truthwatcher spren

Odium's influence

Some spren of Odium are also sapient, making them true spren. Unlike their Honor- and Cultivation-aligned kin, sapient voidspren are capable of retaining their higher functions in the Physical Realm without bonding a person. Those spren are usually imprisoned on Braize, along with the rest of Odium's forces, but they are capable of escaping and traveling to Roshar. They tend to look like small Shin humans, and have colors such as yellow or red. Whether sapient voidspren are capable of granting powers to other creatures is uncertain.

Sja-Anat has also gained the ability to corrupt true spren -- something she was unable to do in the past Desolations. Spren corrupted by Sja-Anat undergo the same type of physical change as the lesser spren. They can still form Nahel Bonds, although the bond will behave somewhat differently in a manner that remains poorly-understood. Notably, the corruption does not force the spren to turn to Odium.

Unique Spren

There is a small number of spren that are one of a kind, with no other like them in the world. Those include the native spren of Roshar, such as Nightwatcher, Stormfather, Cusicesh and the Sibling, as well as ten great spren of Odium called the Unmade. Each of them appears to have a unique power or ability -- for example, Nightwatcher can grant boons and banes, Moelach can induce Death Rattles, and the Stormfather commands the highstorms. The intelligence of unique spren varies greatly -- while some have almost humanlike minds, others are animalistic and act more as forces than they do as people. The former are capable of communicating with humans, and picking who can and cannot hear them.

At least some unique spren can be bonded. Bondsmiths gain their powers from such bonds, with Stormfather being one of the three great Bondsmith spren. Some Unmade also bond with people -- Yelig-Nar grants the use of all ten Surges to whoever swallows a gem containing him, and Re-Shephir attempts to displace a Nahel Bond. Whether an Unmade can become a Bondsmith spren is unknown at this point in time.

Symbiotic Relationships

Some types of spren exist in symbiotic relationships with various other creatures living on Roshar. In most cases, such a relationship is facilitated by a gemheart, a crystal inside a creature's body that allows them to house the spren.

Bonds with animals

Large animals, most notably the greatshells, utilize spren bonds to grow to enormous sizes that would not be otherwise possible. There seem to be two types of spren facilitating this -- an unknown type living in their gemhearts, and mandras, which decrease the pull of gravity on their bodies. Skyeels also form bonds with mandras, which allow them to outright fly despite not having wings.

Non-crustacean creatures forming spren bonds include the Ryshadium, a breed of horses which have evolved to attract some type of spren -- most likely musicspren. This bond is the possible reason for the Ryshadium's unusually high intelligence, as well as their prodigious strength and other adaptations to Rosharan environment. The "magic fish" of the Purelake are another example of Rosharan fauna forming symbiotic bonds with spren. Eating the fish grants numerous benefits, ranging from medicinal, like curing aches, to outright supernatural, like predicting when someone will come to visit or locating missing persons. Whether or not the Ryshadiums and the fish have gemhearts is unknown.

Singer Forms

Singers can attain different forms by taking a spren into their gemheart during a highstorm. Each such form comes with a slightly different physical shape, and even different biology -- for example, only mateform, slaveform, and possibly dullform are capable of reproducing, while warform is taller and more muscular, with ridges and natural plating to protect its wearer.

Such bonds are formed only with non-sentient spren, and once the singer changes a form, the spren is released from the gemheart, unharmed. When the bond is formed with a lesser voidspren, the singer gains a Regal form.

Nahel Bond

For more information, see Nahel Bond.

Each Order of the Knights Radiant forms a Nahel Bond with a different type of true spren. This bond is similar in nature to the bond between a seon and its master, albeit unlike a seon bond, a Nahel bond grants numerous benefits to both parties. The spren gains the capacity to retain higher mental functions while bonded; their partner gains access to Surgebinding. Though historically, only humans could become Surgebinders, during the True Desolation some spren have managed to form a Nahel Bond with a singer, although how this changes things is unknown.

Each Nahel Bond grants access to two Surges, with every Surge shared between two orders. Surgebinders that are organized into proper Orders, rather than acting on their own, are known as Knights Radiant.

The bond between a Knight and their spren can be strengthened by verbally or mentally stating certain Ideals or ideas related to their Order. Once the bond has strengthened to a certain point, the spren gains the ability to become a Shardblade when needed. A sword is the base form for a Shardblade, since they were fashioned after the Honorblades, but they can become any shape their Knight needs, such as a spear, hammer, or shield. While in a Shardblade form, the spren can communicate with their Surgebinder through their mind.

Spren known to facilitate Nahel Bonds include:

• Honorspren (Windrunners)
• Highspren (Skybreakers)
• Ashspren (Dustbringers)
• Cultivationspren (Edgedancers)
• Cryptics (Lightweavers)
• Inkspren (Elsecallers)
• Reachers (Willshapers)

Bondsmiths powers are granted by some of the unique spren, including Stormfather. The names of spren of the orders of Stonewards and Truthwatchers are not known at this point, although the spren themselves have been seen. A Truthwatcher spren appears as a patch of light, as if reflected from a mirror, while in the Physical Realm; a Stoneward spren looks like a humanoid figure with skin of cracked stone and molten light glowing from within while in Shadesmar.

Known Subtypes

Alespren

Alespren

“ Test successful. Have noted spren who appear only when one is severely intoxicated. Appear as small brown bubbles clinging to objects nearby. Further testing may be needed to prove they were more than a drunken hallucination. ”

— Axies the Collector

A rare type of spren that appear only in Iri. They are occasionally seen by people who are under the influence of alcohol. They look like small brown bubbles that cling to objects close to the observer. They were given the name "alespren" by Axies the Collector, a scholar who studies spren, after considering the name "intoxicationspren". The locals refer to them as sudspren. They may also be called winespren.

Axies theorized their existence, but was only able to observe them once, leading him to doubt whether they're real. As there are other stories of people seeing them, their existence is likely.

Angerspren

“ Vamah was watching them stand there, and his expression was as thunderous as a highstorm, angerspren boiling up from the ground around him like small pools of bubbling blood. ”

— The Way of Kings: Chapter Fifteen

A common type of spren that appear around people experiencing anger. They, generally, have the appearance of pools of boiling blood bubbling up from the ground around the feet of the angry individual.

Among the Parshendi, angerspren have the appearance of bolts of lightning that radiate out from the feet of the angry individual.

In Shadesmar, they have an unspecified appearance but make a loud screeching noise similar to sheets of steel grinding against each other when attracted. Angerspren are said to be "nasty" and very dangerous even to other spren. The pools of boiling blood seen in the Physical Realm are actually saliva drooling from their mouths.

Anticipationspren

“ A few anticipationspren—like red streamers, growing from the ground and whipping in the wind—began to sprout from the rock and wave among the soldiers. ”

— The Way of Kings: Chapter Six

A common type of spren that appear around people looking forward to something, or nervous about something. They appear as red streamers that grow out from the ground and blow in the wind. They often appear around soldiers directly before a battle.

The streamer that appears in the Physical Realm is the tongue of the anticipationspren. The spren itself has a round bulbous body and is about the size of a human toddler. It will open its mouth and stick its tongue in the air when near feelings of anticipation.

Ashspren

For more information, see Ashspren.

A type of sapient spren that forms Nahel Bonds with the Knights Radiant Order of Dustbringers, granting them their powers. Ashspren grant the Surges of Division and Abrasion. In Shadesmar, they hava humanoid form with ash-white skin that falls away when the ashpren moves, revealing boness underneath before quickly growing back. Their appearance is unknown, as they seem to have the ability to hide from both other humans and other spren.

They seem to be fond of destroying the things around them.

Awespren

“ A single awespren, like a ring of blue smoke, burst out above him, spreading like the ripple from a stone dropped in a pond. Shallan had seen such a spren only a handful of times in her life. ”

— Words of Radiance: Chapter 78

A very rare type of spren that appear around people who are very awestruck. They take the form of a ripple of blue smoke spreading slowly outwards. They usually appear above and around the awed person's head, like a halo. Most of the time, only a single one can be seen at once, though a whole group of people can attract several.

Bindspren

“ He thought he could faintly make out tiny spren, dark blue and shaped like little splashes of ink, clustering around the place where the rock met the wall. ”

— The Way of Kings: Chapter Fifty-Seven

Spren that appear around objects bound with a Full Lashing. They appear as small splashes of dark blue ink. Their relationship to the Lashings is not fully understood -- Kaladin believes they are what hold the objects together, while Sylphrena disagrees, saying they could be attracted to the Full Lashing Kaladin had created.

Captivityspren

“ It appears I'll have another chance to search for captivityspren. ”

— Axies the Collector

A type of spren theorized by Axies to appear around people in captivity. Despite being imprisoned numerous times he has never observed them, leading him to doubt their existence. However, while imprisoned, Kaladin sees strange spren like taut wires crossing before him, which have been confirmed to be captivityspren.

It's possible that rather than being attracted to the state of being imprisoned, captivityspren are attracted to the feelings of being trapped. This would explain why Axies, who sees being in prison as an opportunity, never witnesses any, while Kaladin's degrading mental state in prison summons several.

Coldspren

A type of spren mentioned in Navani's notebook. They can be captured in gems of a certain cut and used in fabrial machines. They look like spikes growing around the affected person's feet.

Urithiru is covered in hundreds of coldspren. It's unclear whether they're attracted to low temperatures or the sensation of being cold.

Concentrationspren

“Concentrationspren rippled in the air like waves overhead. ”

—Oathbringer: Chapter 53

A type of spren that looks like ripples in the air, similar to a drop in the pond, although without the pond. They are rare in Alethkar, but can be found in Urithiru and Tashikk. They most commonly appear around people who are deeply focused on their task.

Creationspren

“ Her drawing gathered about a half-dozen of them, pulling them by her act of creation just as a bright fire would draw flamespren. ”

— The Way of Kings: Chapter Seven

An uncommon type of spren that appear around creative acts such as painting or drawing. They are of medium-size, about finger-length, and glow with a silvery light. They take the form of objects they have recently seen, but move them in odd ways, such as a table that rolls like a wheel.

When drawing, the more skilled one is, the more likely creationspren are to appear.

Cryptics

Drawings of Pattern

For more information, see Cryptic.

A type of sapient spren that forms Nahel Bonds with the Knight Radiant Order of Lightweavers, granting them their powers. Cryptics grants the Surges of Transformation and Illumination to their bonded human. They are also known as liespren or truthspren. They represent fundamental mathematical laws of nature, and truths that explain the fabric of existence.

In the Cognitive Realm, they have the appearance of figures in robes that hang stiffly, as if made of glass rather than fabric. Instead of heads, they have a floating symbol full of impossible angles and geometries. In the Physical Realm, Cryptics take the shape of a complex and constantly shifting geometric pattern slightly raised off a surface or object. They can also manifest as a floating three-dimensional mass of twisting lines.

Cultivationspren

For more information, see Cultivationspren.

A type of sapient spren that forms Nahel Bonds with the Knight Radiant Order of Edgedancers, granting them their powers. Cultivationspren grant the Surges of Abrasion and Progression. They appear in the Physical Realm as a growing vine with crystals, while in Shadesmar, they take a form of a humanoid seemingly made out of thickly-bound, thin wines and pieces of crystal.

Cultivationspren are ruled by a group of them called the Ring, which, among others, dictates which spren are to bond who. They also have the capacity to let their kinsmen travel into the Physical Realm without the usual accompanying loss of mental functions.

Deathspren

by Marianne EieDeathspren

“ Only the dying could see deathspren. You saw them, then died. Only the very, very lucky few survived after that. Deathspren knew when the end was close. ”

— The Way of Kings: Chapter Thirty-Eight

A type of spren that appears only to people near death. Very few people survive after seeing deathspren, and due to their rarity, some consider them not to be real. They look like black, many-legged, fist-sized creatures, with glowing red eyes that leave trails of light when the deathspren moves. They whisper with voices like paper being torn. Lirin said that deathspren are repelled by water.

It's possible that deathspren have a more direct effect on the dying than simply being attracted to them, as Syl strives to protect Kaladin from them when he's close to death.

Decayspren

“ I didn't know men got this old. You sure he's not decayspren wearing a man's skin? ”

— Sylphrena to Kaladin

A type of spren referenced by Sylphrena. It appears that they are attracted to things that have been abandoned or neglected, as well as rotting food. They look like barnacles, and usually appear in large numbers, huddling close together.

Exhaustionspren

“ She noticed something sweeping through the air above her. She cringed, looking up to find large, birdlike creatures circling around her in Shadesmar. They were a dark grey and seemed to have no specific shape, their forms blurry. ”

— Words of Radiance: Chapter Eleven

A type of spren that appear around exhausted people. In the Physical Realm, they appear as brown-colored jets of dust shooting up in the air. In Shadesmar, they seem indistinct yet also large and birdlike.

Fearspren

“ Fearspren—wiggling and violet—sprang up through the wood and wriggled in the air. ”

— The Way of Kings: Chapter Six

A common type of spren that appear around people experiencing fear. They look like small, violet globs that crawl up from out of the ground and gather around the feet of the fearful. They seem to be attracted to the highest concentration of fear in an area; people experiencing less fear will fail to attract fearspren. In Shadesmar, fearspren appear as eel-like creatures with stumpy legs, ridges on their backs, and long purple antennae: the antennae appear to be the part that visually manifest in the Physical Realm.

Among the listeners, fearspren look like long purple worms.. This is probably because they can see the entire antenna and not just the tip which humans see.

Fermentationspren

A type of spren related to fermentation.

Flamespren

“ ...instead watching a pair of flamespren dance along one of the logs. These seemed vaguely human, with ever-shifting figures. ”

— Oathbringer: Chapter Thirty-Six

A common type of spren that appear around and in fire. They look like tiny humanoid figures made of congealed light. They will often dance around, constantly changing in size, shape, and luminosity like the flames themselves.

The ardent Geranid was studying flamespren when she discovered that if she measured them, the spren seemed to be "stuck" by that measurement. This is similar to the physical process of wave-function collapse in quantum mechanics.

Gloomspren

“Long, grey, like a tattered streamer of cloth in the wind. It wound around him, fluttering. ”

— Oathbringer: Chapter Five

A rare type of spren that looks like a grey streamer, seemingly attracted to the feeling of resignation or deep sadness. Syl's aunt hunts them in a manner similar to a greatshell hunt.

Gloryspren

“ Below, his men cheered, sending up calls that rose above the Parshendi war chant. Gloryspren sprouted around him. ”

— The Way of Kings: Chapter Sixty-Five

A type of spren that appear around people when they experience pride in their accomplishments. In the Physical, they look like as golden orbs of translucent light, while in the Cognitive, they take the form of avian-like creatures with bulbous bodies, long wings, and flowing tails, with a golden ball for a head.

Gravityspren

A type of spren mentioned in Navani's notebook. They can be captured in gems of a certain cut and used in fabrial machines. They are possibly another name for groundspren or luckspren.

Greatshell Spren

A type of spren that has a symbiotic relationship with greatshells, enabling them to grow to such large sizes. They look like tiny tongues of smoke, such as those from snuffed candles, but can only be seen when they leave a greatshell's corpse after it has been killed.

The Tai-na of the Reshi Sea have an extraordinary variant of spren, referred to as the "soul" of the greatshell by the Reshi. It allows them to grow to far more gargantuan sizes. These "souls" will sometimes show themselves to people. They seem to have some measure of control over the Surge of Gravitation, letting them slow a person's fall.

Groundspren

A type of spren to which Rosharans attribute the pull of gravity.

Heatspren

A type of spren mentioned in Navani's notebook. They can be captured in gems of a certain cut and used in fabrial machines. It's uknown whether this is a scientific name for a flamespren, or a different creature entirely.

Highspren

For more information, see Highspren.

A type of sapient spren that forms Nahel Bonds with the Knights Radiant Order of Skybreakers, granting them their powers. Highspren grant the Surges of Gravitation and Division.

In the Physical Realm, highspren are described as looking like black slits in reality, with white glowing stars shining through. They seem to have their own settlements in Shadesmar and appear rather isolationistic, with none to be seen in places like Celebrant. Other spren consider them to be strict and rule-bound.

by Marie Seeberger Sylphrena, an honorspren

Honorspren

For more information, see Honorspren.

A type of sapient spren that forms Nahel Bonds with the Knights Radiant Order of Windrunners, granting them their powers. Honorspren grant the Surges of Gravitation and Adhesion. They are said to be quite "discerning" in deciding who they would bond with.

In the Physical, they can change their forms, although in any shape, they are blue-white with a matching glow. In Shadesmar, they look like humans with blue-white skin and clothes that are part of them. They are noted to be highly warlike, with numerous cities and fortresses, as well as their own fleet.

Sylphrena is an honorspren.

Hungerspren

“ As he spoke, he attracted a few hungerspren. They looked like brown flies that flitted around the man's head, almost too small to see. ”

— The Way of Kings: Chapter Two

A type of spren that appears around people experiencing extreme hunger. They appear as tiny brown flies that flit around the hungry person.

Inkspren

For more information, see Inkspren.

A type of sapient spren that form Nahel Bonds with the Knights Radiant Order of Elsecallers, granting them their powers. Inkspren grant the Surges of Transformation and Transportation. They look like small, human-shaped figures with ink-black skin and clothing, coated in what seems to be oil, with a mother-of-pearl or prismatic quality to their look. They are capable of blending into shadows.

Joyspren

“ Joyspren rose around her, like blue leaves that started at her feet then moved up in a swirl before flaring out above her as if in a blast of wind. ”

— Words of Radiance: Chapter Twenty-Eight

A relatively rare type of spren, usually accompanied to intense feelings of happiness or accomplishment. They take form of a blue leaves or petals that rise around a person in a flutter, circling them or trailing behind as the person moves.

Keenspren

A type of spren mentioned by Wyndle, who considers 'growing a garden for keenspren' to be a comparison point for the weirdness of a conversation.

Laughterspren

“ A few laughterspren—minnow-like silver spirits that darted through the air in circular patterns—began to zip about them. ”

— The Way of Kings: Chapter Fourteen

A type of spren that appears in the presence of laughter. They have the appearance of small, silver minnows that dart in circular motions around those who are laughing.

Liespren

Another name for Cryptic.

Lifespren

“ A few lifespren—tiny, glowing green specks—floated around the shalebark mounds. Some danced amid the rifts in the bark, others in the air like dust motes zigzagging up, only to fall again. ”

— The Way of Kings: Chapter Thirty-Nine

A common type of spren that appears around plantlife, particularly just after highstorms. They look like motes of glowing green dust, or swarms of tiny, translucent insects. In the Cognitive Realm, they look very similar, but they have tufts of white hair that ripple as the lifespren move.

Rarely, lifespren may appear in particularly populated areas.

Lightspren

For more information, see Lightspren.

A type of sapient spren that formed Nahel Bonds with the Knights Radiant Order of Willshapers, granting them their powers. Lightspren grant the Surges of Transportation and Cohesion. In the Physical Realm, they appear as glowing balls of light. In Shadesmar, they appear as humans with metallic bronze skin and holes for pupils, like living statues. There, they are also known as Reachers.

Reachers are often guides in Shadesmar, as they like to travel to different places, trading and selling goods. They have ships pulled by teams of mandras, inlaid with lines of copper that may serve as a medium of communication.

Timbre and Ico are lightspren.

Logicspren

“ There were said to be logicspren—in the form of tiny stormclouds—who were attracted to great arguments... ”

— The Way of Kings: Chapter Seven

A rare type of spren that appear around good and well-thought-out arguments. They take the appearance of tiny stormclouds. They seem to be quite rare, although they can often be seen in Azir.

Sketch of Luckspren

Luckspren

For more information, see Mandras.

A type of spren that flies around skyeels and some greatshells. In the Physical, have the appearance of tiny, blue, arrowhead-like fish that dart around the skyeel in the general direction of its travel. It is commonly believed by Rosharans that they allow the skyeel to fly in some manner, but the accuracy of this belief is not known.

In Shadesmar, luckspren are known as mandras. There, they are far larger, with long, sinuous bodies and arrow-shaped heads. They are often harnessed by various spren to pull ships through the seas of beads, as there is no wind to sail on. They have a habit of "dropping out", vanishing temporarily into the Physical Realm, and then reappearing in Shadesmar, necessiting any single ship to have several mandras hitched to it.

Mistspren

A type of sapient spren, albeit one that is not affiliated with any order of the Knights Radiant. They have only been seen in Shadesmar, where they look like humanoid figures made out of swirling, indistinct fog. Their faces look like porceilain masks, and they wear gloves, trousers and vests that adhere to their bodies' shape despite their seeming incorporeality.

They seem to be affiliated with honorspren, working as common sailors on their ships.

Musicspren

A windspren in Shadesmar is described as a pinprick of light trailing a long luminescense behind it, moving much like it would in the Physical Realm.

Windspren are closely related to honorspren, such as Sylphrena. This perhaps evidenced by their ability to stick things together, making use of a rudimentary version of the Surge of Adhesion. They generally use this ability to play pranks on people, doing things like sticking shoes to stone or sticking shoelaces together to cause someone to trip.

Corrupted Spren

Myths and Lore

Dawnsingers

According to the ardent Kabsal, the Dawnsingers were "kindly spren sent by the Almighty" to care for mankind after being expelled from the Tranquiline Halls. This is proven to be untrue as the Dawnsingers were the original inhabitants of Roshar that later became Parshendi.

Nightspren

A type of spren believed to exist by more traditional, rural followers of Vorinism. Those with more education believe they are simply fabrications of the Knights Radiant to support their dominance.

Voidbringers

During the Era of Solitude on Roshar, most people living in cities believed the Voidbringers were a type of evil spren.

Theories and Speculation

This page or section deals with theories or speculation.

Please read carefully and note that this is not necessarily canonical.

Cousin spren

Each order of the Knights Radiant bonds to a different true spren, and each has been shown to attract a different kind of lesser spren in various circumstances. For example:

• Kaladin, a Windrunner, attracts windspren on numerous occassions, most notably when fighting Szeth and when forming the "wind break" in Revolar. Windspren are also called Syl's "cousins" several times.
• Shallan, a Lightweaver, has been known to gather a large number of creationspren when drawing or crafting illusions. Although this might simply be a function of her being an artist, the numbers Shallan attracts are unnatural, with hundreds surrounding her at one point.
• Lift, an Edgedancer, attracts lifespren from time to time.
• Dalinar Kholin, a Bondsmith, brings together an incredible amount of gloryspren during the Battle of Thaylen Field.
• Also during the Battle of Thaylen Field, Jasnah, an Elsecaller, is surrounded by a glow of geometric patterns for a moment.

What this means, if anything, is uncertain; it has been speculated that the lesser spren will eventually form Shardplate, once the Radiants reach a high enough level.

Bondsmith spren

The singular nature of the Bondsmith spren has led to some speculation regarding which named spren could bestow a Bondsmith Nahel Bond. Candidates commonly put forth include:

• Nightwatcher, whom Brandon has previously stated is on the same level as Stormfather
• Cusicesh, as it's a powerful spren that's worshipped by the people watching it
• The Sibling, based on their connection to Urithiru and Stormfather's comments about how humans had harmed them before

Trivia

• It is possible for someone to bond multiple spren
