A '''fabrial''' is a [[StormlightLight]]-powered mechanical device from [[Roshar]] that uses [[spren]] captured in gemstones to perform a particular supernatural task.

== History ==
Pre-Shattering, [[Adonalsium]] prevented fabrials from existing.{{wob ref|13333}}
 
During the [[Heraldic Epochs]], the [[Knights Radiant]] knew how to create [[Surge]] fabrials, includingreplicating all Radiant abilities except those of a [[SoulcasterBondsmith]]s, healingusing fabrials, andthe [[Oathgate]]s as a guide.{{wob ref|15347}} Their knowledge of non-Surge fabrials, which the modern fabrial science concerns itself with, was far less advanced than that of the current scholars.{{book ref|sa3|96}} Some principles, however, were known even then: among others, the lifts in [[Urithiru]] were created with conjoining fabrials.{{book ref|sa3|24}} With the fall of the Radiants, knowledge of most fabrials was lost, with Soulcasters as the major exception. Over time, the stories of Radiant fabrials became vastly exaggerated, with many people believing that they were far more numerous, and much more advanced, than what modern science has created.{{book ref|sa3|96}}
 
According to [[Nikli]], the original Aimians used devices to terraform Aimia to make it habitable, equating those devices with early fabrials. [[Nikli]] insinuates that the [[scouring of Aimia]] was caused by destruction of these fabrials during a number of wars, perhaps the Desolations, because the islands of Aimia could not sustain life without them. {{book ref|sa3.5|9}}
 
While the fabrials were known for centuries, it was only recently that the pace of fabrial inventions picked up, with creations such as the heating fabrials and [[spanreed]]s being only a few decades old at most. Most research occurs in the eastern nations of [[Alethkar]] and [[Jah Keved]], with [[Navani Kholin]] as a particularly important patron. [[Half-shard]]s, an important breakthrough in fabrial research that attempts to mimic [[Shardplate]], were only perfected in 1173, at the tail end of the [[Era of Solitude]].{{book ref|sa1|22}}

Creating modern fabrials requires trapping the proper type of [[spren]] in a gemstone cut for that purpose.{{book ref|sa3|33}} To trap the spren, artifabrians lure it intoto a gemstone with something it loves and knows well. Once it is lured into the gem, the spren cannot easily escape.{{bookepigraph ref|sa3sa4|1001}} The typesgemstone ofmust spren that cannot be capturedfully ininfused, abut [[polestone]]needs dependto onhave thesome gem'sLight type and color, implying that there are thousandsinside of possible combinations.{{file ref|Navani1.jpg|text=Navani's Notebook: One}} These fabrial-gems are encased in a wire frame, but it is unknown whether this has an effect on the fabrial.

Once it is lured into examining the gemstone, artifabrians drain the Light from the gemstone, using the Arnist Method, which involves placing some larger gemstones around the gemstone to drain the Light, using a [[larkin]], or using tuning forks.{{epigraph ref|sa4|3}}{{epigraph ref|sa4|4}}{{book ref|sa4|42}} If the Light is sucked out of the gem quickly enough, the spren will be sucked into the gemstone. After the spren is stuck, the spren can be manipulated to the artifabrian’s content.{{epigraph ref|sa4|5}} The types of spren that can be captured in a [[polestone]] depend on the gem's type and color, implying that there are thousands of possible combinations.{{file ref|Navani1.jpg|text=Navani's Notebook: One}}{{book ref|sa4|42}} These fabrial-gems are encased in a metal wire frame, which determines the effect of the fabrial, along with the type of spren.{{epigraph ref|sa4|6}} Their power can be determined by the pattern of Light that gets filtered through the gemstone, although it cannot be seen with the naked eye.{{file ref|Navani2.jpg|text=Navani's Notebook: Two}} Spren corrupted by [[Sja-anat]] will behave differently in a fabrial.{{wob ref|11659}} It is possible for synthetic gemstones to be used in fabrials.{{wob ref|2702}}
It appears that fabrials are affected by the frame of reference of their user. For example: a spanreed being used on a ship at sea will also transfer the motion of the ship to the conjoined spanreed unless the user can conceive of both spanreeds as belonging to the same frame of reference. {{book ref|sa3.5|5}} The exact cause of this is unknown, but suspected to be related to spren response to human perception.▼
 
=== Surge Fabrials ===▼
How the ancient [[Surge]] fabrials were created is unclear, but it is likely a different method. Their functioning is also different: for example, [[Soulcaster]]s require a request for aid, which is unnecessary in modern fabrials.{{book ref|sa3|i|4}} However, they still do involve spren being bound to gemstones in some way - two large spren can be seen guarding and controlling the [[Oathgates]] in [[Shadesmar]].{{book ref|sa3|116}} So long as the gemstones are preserved and the spren are not compromised, any Surge fabrial can be recreated to operate just as it used to.{{book ref|sa3|117}} Any [[Surge]] can be replicated by fabrial science.{{wob ref|3013}} However, in the present day, fabrials that use Surges are extremely rare, and most of them date back to the era of the [[Knights Radiant]].{{cite}}▼
 
In contrast to [[Surgebinding]] or [[Old Magic]], most fabrials can be operated by anyone, as long as they know how to do so (the only exception being the [[Oathgate]]s, which require a Radiant to activate, although that might be a security measure rather than a crucial design element).{{book ref|sa2|86}} Some, like heatrials, are even capable of functioning without human input.{{book ref|sa2|4}} The self-contained nature of fabrials sets them apart from most manifestations of [[Investiture]] in the [[cosmere]], wherein the magic is accessed and directed by the user (often with specific requirements or limitations).{{wob ref|10311}}{{wob ref|3488}}{{wob ref|6247}}

=== Reactions to Metal ===
Once trapped in a gem, spren respond to stimuli in consistent and predictable ways. The metal frame surrounding the gem creates the stimuli the spren react to - pressing metal against a flamespren in a ruby increases and decreases heat.{{book ref|sa3|33}} Spren react to different metals in different ways., Thiswith parallelstheir behavior generally paralleling the [[Allomantic]] usespowers offor theseeach metalsindividual metal.{{epigraph ref|sa4|7}} Multiple fabrial gems can be placed inside a single wireframe, which lets them work together to create more complex results. The [[emotion bracelet]], for example, has ten gems, with patterns in which they light up corresponding to different emotions.{{file ref|Navani2.jpg|text=Navani's Notebook: Two}} The [[God Metal]] which [[Shardblade]]s are composed of can be used in fabrials.{{wob ref|14138}}
==== Zinc ====▼
[[Zinc]] in contact with a gemstone will cause its captured spren to more strongly manifest, this parallels how allomantic zinc amplifies, or riots the emotions of others. {{book ref|sa4|7}}
==== Brass ==== ▼
[[Brass]] in contact with a gemstone will cause its spren to withdraw and its power to dim, this parallels how allomantic bronze diminishes, or soothes the emotions of others. {{book ref|sa4|7}}▼
==== Bronze ====▼
[[Bronze]] in contact with a gemstone will cause it to alert someone of objects, entities, or phenomena nearby by increasing its brightness. This parallels allomantic bronze, which can be used to sense allomancy, and theoretically, other types of investiture usage.{{book ref|sa4|8}}{{book ref|sa1|i|4}}▼
==== Pewter ====▼
[[Pewter]] in contact with a gemstone will cause it to express a certain attribute in force, correlated to the type of spren trapped in the gemstone. This parallels allomantic pewter, which is used to strengthen the physical attributes of its user. This also drains [[stormlight]] faster than other types of fabrials, which might be similar to how allomantic pewter 'burns' faster than most other metals. {{book ref|sa4|9}} This metal is the one used to create Augmentor fabrials.▼

=== Modification with aluminum ===
If a fabrial is used inside a room lined with aluminum, it will beis impossible to sense the use of the fabrial from outside of that room. If the fabrial requires outside connection (e.g. conjoiner, and specifically spanreed), the conjoined half outside of the room will not function properly because the pairing has been interrupted. If the fabrial can be used entirely within the room (e.g. a soulcasterSoulcaster), it will operate as designed but be undetectable from outside.{{book ref|sa3|81}}
 
It is possible to alter the function of a conjoiner (ruby) fabrial to transfer only certain components of motion between the conjoined halves (e.g. A spanreed that can only transfer vertical motion, but not lateral) by inserting pieces of aluminum foil into the fabrial gemstone housing. It is thought that aluminum impacts a spren's ability to sense thoughts, and therefore this may function by blocking parts of the "signal" between the two gemstones.
The ardent [[Rushu]]'s experimentation with this behavior results in a mobile chair for [[Rysn]] which hovers by being vertically reverse coupled to a heavy object (an anchor which is allowed to fall a short distance) but remains laterally uncoupled allowing for free motion when pushed. Rushu notes that the chair's rotational motion remains coupled, but believes it would be possible to fix that upon further refinement.{{book ref|sa3.5|8}}
 
There are no confirmed instances of other types of fabrial being modified by aluminum in the same way. Reverser (amethyst) fabrials are stated to operate similarly to conjoiners and therefore likely behave similarly under aluminum modification.{{book ref|sa3.5|5}} It is unclear what effect aluminum would have on fabrials that do not rely on two paired gemstones. Attractor fabrials would have a "shadow" if partially blocked by aluminum. Though the attraction will bend round the edges, in the same way as light would bend.{{wob ref|16021}}

== Types ==
{{for|:Category: Fabrials|a full listing of known fabrial machine designs}}
Modern artifabrians divide the fabrials they design into five groups across three categories.{{book ref|sa1sa4|part=ars}} Ancient fabrials, including Surge fabrials, do not fit into these categories and are grouped separately.
 
=== Altering fabrials ===
Appropriately named, altering fabrials qualitatively alter the property or attribute they target. Well-known examples include altering the temperature of an object or an area and enhancing or dampening the sensation of pain, though artifabrians believe there is potential for even greater types of fabrials in this category.{{book ref|sa1sa4|part=ars}}
 
==== Augmenters ====
Altering fabrials that increase or enhance an attribute are known as augmenters. They work best with forces, emotions or sensations.{{book ref|sa1sa4|part=ars}} [[Half-shard]]s and [[Grandbow]]s are examples of augmenters that increase durability.{{book ref|sa1sa4|part=ars}}{{book ref|sa1|12}} There are also heating fabrials that generate heat, sometimes called warmers or heatrials.{{book ref|sa1|15}}{{book ref|sa3|62}}{{book ref|sa3|100}} Heatrials were first developed just before [[Assassination of Gavilar|Gavilar's feast]], though earlier models were much less effective.{{book ref|sa3|prologue}} Painrials that enhance the feeling of pain also fall under this category.{{book ref|sa3|118}} Pewter is used for augmenters.{{epigraph ref|sa4|9}}
 
==== Diminishers ====
Diminishers act as opposites of augmenters, decreasing the magnitude of their targeted trait. In general, they operate in a similar manner to augmenters, with similar restrictions.{{book ref|sa1sa4|part=ars}} [[Painrial]]s that decrease pain are a type of diminisher.{{book ref|sa1|60}} Tin is used to make diminishers.{{epigraph ref|sa4|10}}
 
=== Pairing fabrials ===
{{image|Navani flying fabrial by Marie Seeberger.jpg|side=right|height=250px|[[Navani]] using a conjoiner fabrial}}
Pairing fabrials are, as the name suggests, created in pairs that can move in parallel, or the opposite, over great distances. This category was a recent discovery during the [[War of Reckoning]].{{book ref|sa1|part=ars}} Force is conserved between each pair of fabrials, and the force required to move one is equivalent one required for moving both. Despite limitations in how far the fabrials can be separated and still work (dictated by certain processes during manufacture), conjectures about possible applications are being discussed.{{book ref|sa1|part=ars}}▼
 
▲Pairing fabrials are, as the name suggests, created in pairs that can move in parallel, or the opposite, over great distances. This category was a recent discovery during the [[War of Reckoning]].{{book ref|sa1sa4|part=ars}} Force is conserved between each pair of fabrials, and the force required to move one is equivalent to one required for moving both. The farther apart the two halves are, the more resistance is felt when moving them.{{book ref|sa4|3}} Despite limitations in how far the fabrials can be separated and still work (dictated by certain processes during manufacture), conjectures about possible applications are being discussed.{{book ref|sa1sa4|part=ars}}
 
By using raysium, a half-spren trapped in one half of a conjoined pair of gems can be transferred to another gem, not part of the original pairing. This can lead to an asymmetry between the movements of the two spren halves, as moving a larger gem a certain distance will now make its smaller paired counterpart move a larger distance. This does not, however, allow for force multiplication.{{book ref|sa4|84}}
 
==== Conjoiners ====
Conjoiners are created from infused rubies which are split in half after the spren is already captured.{{book ref|sa4|84}} The two halves are then able to exhibit parallel movements over large distances. [[Spanreed]]s are the most widespread example of conjoiner, linking two pens and allowing for long-distance communication.{{book ref|sa1|28}}{{book ref|sa1sa4|part=ars}} Conjoined rubies don't drain much Light to maintain their connection.{{book ref|sa4|63}}
 
==== Reversers ====
Reversers are created in a similar manner to conjoiners, using an amethyst instead of a ruby. The two halves are then able to exhibit equal, but opposite reactions; lifting one would cause the other to be lowered.{{book ref|sa1sa4|part=ars}}
 
=== Warning fabrials ===
Warning fabrials detect things and give notice to the user. Their range depends on the the amount of Stormlight infused into its fabrial-gem.{{book ref|sa1sa4|part=ars}}
 
==== Alerters ====
Alerters use a heliodor to detect the presence of objects, feelings, sensations, or phenomena, and warn the user. There are alerters which can detect approaching people while excluding certain persons from detection.{{book ref|sa1sa4|part=ars}} The [[Emotion bracelet]] is an alerter able to detect different emotions.{{file ref|Navani2.jpg|text=Navani's Notebook: Two}} Bronze is the metal used to stimulate these types of fabrials.{{book ref|sa4|8}} Theoretically, a fabrial could be used to detect emotional [[Allomancy]].{{wob ref|11576}}
 
=== Attracting fabrials ===
 
==== Attractors ====
Attractors can be used to attract many different types of substances, from smoke above a fire to humidity in the air. {{book ref|sa2|43}}{{book ref|sa2|82}} Iron is a main component in their construction. {{book ref|sa4|11}}
 
{{image|Oathgate_Spren.jpg|An Oathgate as seen from [[Shadesmar]]|side=left|width=200px}}
 
===Surge Fabrials===
These are fabrials that are able to manipulate Surges, replicating the effects of [[Surgebinding]] and [[Voidbinding]].{{wob ref|3013}}{{wob ref|15347}}{{wob ref|7029}}
 
==== Soulcasters ====
{{for|Soulcasting}}
 
These fabrials mimic the the Radiant ability of [[Soulcasting]]. {{book ref|sa1|72}} A Soulcaster fabrial consists of two rings and a bracelet connected by chains which hold a group of three gemstones across the back of the hand. Most are only able to effect small, singular changes, such as turning stone into water, while about one in ten can effect any change.{{book ref|sa1|5}} They can be activated by tapping one of the three gemstones when holding the hand against what is to be changed.{{book ref|sa1|42}} They manipulate the Surge of Transformation.
 
==== Regrowth fabrial ====
{{for|Oathgate}}
 
These fabrials manipulate the Surge of [[Transportation]], and allow the user to transport anything on top of the platform and in the control chamber between Oathgates in an instant. However, as far as is known, they function in pairs - an Oathgate in [[Urithiru]] only connects to one Oathgate outside, and the Oathgate outside only connects to one Oathgate in Urithiru. They can only be activated by living [[Shardblade]]s, as wielded by the [[Knights Radiant]], or an [[Honorblade]].{{book ref|sa2|86}} Transportation of more than one person through them requires use of more Stormlight.{{book ref|sa2|87}}
 
=== Unknown types ===
{{image|Fabrial Watch.jpg|A fabrial wristwatch|side=right|width=300}}
==== Clock ====
Rosharan clocks are fabrials, with their mechanisms powered in some fashion by an infused smokestone in their center, holding a captured [[logicspren]].{{citeepigraph ref|sa4|15}}{{book ref|sa1|10}} They are noted as being rather expensive, although in recent years they have become more and more common.{{book ref|sa2|12}}{{book ref|sa2|49}} Dozens of them can be found in [[Kharbranth]]. Many have bells hanging from them to announce the hour.{{book ref|sa1|3}} In the past, they came only in standing and hanging varieties.{{book ref|sa1|10}}{{book ref|sa1|8}} Recently, Navani has managed to create a design small enough to wear on one's hand.{{book ref|sa3|16}}
 
==== Attractor ====
Used to attract certain substances,{{book ref|sa2|67}} possibly determined by the gemstone used. They use iron in their metal lattices.{{citeepigraph ref|sa4|11}} During the [[Battle of Narak]], Navani unveils one capable of drawing moisture from the air, pooling the water into a globe around the garnet that powers it.{{book ref|sa2|82}} [[Shallan]] spots one that gathers smoke from a fire in the [[Ghostbloods]]'s hideout at the [[Shattered Plains]].{{book ref|sa2|43}} The ''[[Wandersail (1174 ship)|Wandersail]]'' is said to have stabilizers made from attractor fabrials that move weights inside the hull to prevent capsizing.{{book ref|sa3.5|11}}
 
It is possible to create a repeller fabrial, possibly using steel.{{epigraph ref|sa4|11}}
 
==== Stabilizer ====
Thaylen engineered fabrials that help to stabilize ships during the highstorm. [[Rysn]]'s ship, ''[[Wandersail (1174 ship)|Wandersail]]'', has been equipped with these fabrials.{{book ref|sa3|i|13}}
 
==== Drainer ====
Though their name is unknown, these fabrials can partially drain stormlightStormlight from gems to diminish their glow, for aesthetic purposes.{{book ref|sa1|55}}
 
==== Urithiru lifts====
The lifts in Urithiru are related to conjoined fabrials working together with sets of gears.{{book ref|sa3|24}} There are empty slots on the railings on which infused gemstones can be inserted, from which the lift will draw Stormlight and begin to move. The lift draws enough power to reach the next floor, and upon reaching the first destination the platform will keep drawing Stormlight from the gemstone to perpetuate the operation of the fabrial. If at any point during the rise or descend the gemstone is removed, the lift will continue to travel until the following floor, stopping at that position. A lever on the platform can be switched to determine the direction of motion.{{book ref|sa3|27}}
 
===Possible= FabrialsSuppressor ====
{{for|suppression fabrial}}
==== Shardplate ====
These fabrials can suppress Surgebinding and Invested entities, such as Fused and Radiant spren.{{book ref|sa4|39}}{{book ref|sa4|49}}
[[Shardplate]] is occasionally referred to as a fabrial. It's unknown whether this is accurate, however, as Shardplate appears to operate in a different manner.
 
▲==== ZincAura ====
{{for|aura fabrial}}
These fabrials can analyze the [[spiritweb]] and [[Connection]]s of a subject.{{book ref|yumi|32}}
 
===Possible Fabrials===
==== Stormclock ====
The wristwatch that [[Dalinar]] receives from [[Navani]] includes a [[stormclock]], which might be a fabrial, although it might as well operate purely mechanically. The vambrace is also equipped with a clock and a diminisher painrial, while Navani's own version has a switch that allows it to turn into an augmenter, for self-defense.{{book ref|sa3|16}}{{book ref|sa3|117}}
 
==== Gemstone columnColumn ====
There is a column of gemstones in [[Urithiru]]'s lower levels which serves as the main residence for the [[Sibling]] and an access point for all of the fabrials found in Urithiru. A certain pattern of gems control the Tower's defenses against the [[Fused]]. [[Raboniel]] used it to corrupt and disable these defenses. The column also has a defense mechanism designed by [[Melishi]] in the form of a glowing barrier that can be activated by four nodes found throughout the tower.
There is a column of gemstones in [[Urithiru]]'s lower level, the purpose of which remains unknown. [[Renarin]] speculates that it might be a fabrial allowing the city to operate properly, although if so, it appears to be non-functional.{{book ref|sa3|29}}
 
==== Stormlight transfer device ====
These devices can move stormlightStormlight between gems, and are used by the moneychangers of [[Celebrant]] to transfer stormlightStormlight into [[Polestone#Perfect_Gemstones|perfect gemstones]].{{book ref|sa3|99}}
 
==== Threnodite shadow detector ====
