A fabrial is a type of mechanical device, powered by Stormlight that uses spren captured in gemstones to perform a variety of tasks. The types of spren that can be captured in a gem depend on the gem's type and color, implying that there are "thousands of possible combinations" of fabrials that can be made. A fabrial-gem's power can be determined by the invisible pattern of Stormlight that gets filtered through the gemstone. These fabrial-gems are encased in a wire frame, but it is not known whether this has an effect on the fabrial. Any surge can be replicated by fabrial science.

The term "fabrial" is often used colloquially to refer to the entire device. Artifabrians, however, use it to refer specifically to a gem with a captured spren, calling the entire device a machine.

History

During the Heraldic Epochs, the Radiants had access to knowledge of Surge fabrials, including Soulcasters, healing fabrials, and Oathgates. They're knowledge of modern fabrial science was not as advanced as modern scholars, though they did have some knowledge. The lifts in Urithiru were created with conjoining fabrials and gears. With the fall of the Radiants, knowledge of most fabrials was lost, with Soulcasters as the major exception. These stories eventually got exaggerated into people believing the Radiants had more fabrial technology than they did. Modern advances in fabrial technology only picked up fairly recently, with Navani as a particularly important patron of research. Most research occurs in the eastern nations of Alethkar and Jah Keved. Half-shards, an important breakthrough in fabrial research, were perfected in 1173.

Creation

Creating modern fabrials requires trapping the proper type of spren in a gemstone cut for that purpose. To trap the spren, artifabrians lure it into a gemstone with something it loves and knows well. Once it is lured into the gem, the spren cannot easily escape. 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. For example, pressing metal against a flamespren in a ruby increases and decreases heat. Multiple fabrial gems can be placed inside a single wire frame, which lets them work together in creating results. The emotion bracelet, for example, has ten gems.

How the ancient surge fabrials were created is not known, but it is likely a different method from modern fabrials. Ancient Soulcasters require a request for aid not seen in modern fabrials. 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. Odium tells the Fused that the Oathgate can be rebuilt if the building is destroyed but the gemstones are recovered and the spren are not compromised.

Types

Modern artifabrians divide the fabrials they design among five groups across three categories. The fabrials they create are all the result of scientific research. Ancient fabrials, including Surge fabrials, do not fit into these categories and are categorized seperately.

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.

Augmenters

Altering fabrials that increase or enhance an attribute are known as augmenters. They work best with forces, emotions or sensations. Half-shards and Grandbows are examples of augmenters that increase durability. There are also heating fabrials that generate heat, sometimes called warmers or heatrials. Painrials that enhance the feeling of pain also fall under this category.

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. Painrials that decrease pain are a type of diminisher, though the term can also be used to describe a pain augmenter.

Pairing fabrials

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. Force is conserved between each pair of fabrials. The force required to move one is equivalent to moving both. Despite limitations in how far the fabrials can be separated and still work, which is affected by certain processes during their manufacture, conjectures about possible applications are being discussed.

Conjoiners

Conjoiners are created from infused rubies which are split in half. The two halves would then be able to exhibit parallel movements over large distances. Spanreeds are the most widespread example of conjoiner, linking two pens and allowing for long-distance comunications.

Reversers

Reversers are created in a similar manner to conjoiners, using an amethyst instead of a ruby. The two halves will then be able to exhibit equal but opposite reactions; lifting one would cause the other to be lowered.

Warning fabrials

An excerpt from Navani's Notebook depicting an Emotion Bracelet and examples of stormlight patterns

Warning fabrials detect things and give notice to the user. Their range depends on the the amount of Stormlight infused into its fabrial-gem.

Alerters

Alerters are able to detect the presence of objects, feelings, sensations, or phenomenon and warn the user. Alerters utilize heliodors in their design. There are alerters which can detect approaching people, which are able to exclude certain people from detection. The Emotion bracelet is an alerter able to detect different emotions.

Surge Fabrials

These are fabrials that are able to manipulate Surges, replicating the effects of Surgebinding and Voidbinding.

Soulcasters

These fabrials mimic the the Radiant ability of Soulcasting. 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. About one in ten can effect any change. They can be activated by tapping one of the three gemstones when holding the hand against what is to be changed. They manipulate the Surge of Transformation.

Regrowth

A female Stoneward possessed what appears to be a fabrial constructed from a large topaz and heliodor that was able to "regrow" and repair injuries. It manipulated the Surge of Growth.

Oathgates

These fabrials manipulate the Surge of Transportation. There are hints that the Oathgates were responsible for the near-instantaneous travel possible during the Heraldic Epochs and were one of the only ways to reach Urithiru. They could only be activated by living Shardblades, as wielded by the Knights Radiant. Transportation of more than one person through the gates required use of more Stormlight for the ten gemstone lanterns within.

Possible Fabrials

Shardplate

Shardplate is occasionally referred to as a fabrial, it is not known if this is accurate since Shardplate appears to operate in a different manner.

Theoretically a fabrial could be used to detect emotional Allomancy.

Trivia

• It is possible for synthetic gemstones to be used in fabrials.
