The '''Sibling''' is a notable [[spren]] on [[Roshar]].{{book ref|sa4|3}} They are of the same power level as the [[Stormfather]] and the [[Nightwatcher]], and is the third spren historically associated with the [[Order of Bondsmiths]].{{book ref|sa4|110}}{{book ref|sa4|116}} The Sibling manifests physically as many fabrials within the tower of [[Urithiru]] and has control over them, with the crystal pillar being the heart.{{book ref|sa4|111}} They are currently bonded to [[Navani Kholin]].{{book ref|sa4|110}}{{book ref|sa4|116}}
 
== Personality and Appearance ==
 
=== Personality ===
 
The Sibling does not trust humanity due to trauma stemming from feeling betrayal at the Recreance. Due to this, they do not want to bond with any human.{{cite}}
 
They despise fabrials due to how they require that spren be imprisoned. They use this as further evidence of mankind's inherent wickedness.{{cite}}
 
They do not identify with any gender, and does not understand why any spren identify with human genders.{{wob ref|11572}}{{book ref|sa4|49}}
 
Despite living thousands of years, they remain somewhat naïve.{{cite}}
 
== Attributes and Abilities ==
The Sibling is known to have been alive for at least four and a half millennia and is functionally immortal.{{book ref|sa3|111}} The Sibling does not view itself as having a gender and finds the notion that [[spren]] do ridiculous.{{wob ref|11572}}{{book ref|sa4|49}} Despite living thousands of years, it remains somewhat naïve. [[Oathgate]] spren follow the orders of the Sibling and refer to the Sibling as a parent.{{book ref|sa4|22}}
 
=== Investiture ===
The Sibling is capable of producing itstheir own [[Investiture]] known as [[Towerlight]], a mixture of [[Lifelight]] and [[Stormlight]], which itthey usesuse to power the [[fabrial]]s in Urithiru.{{book ref|sa4|69}} ItThey needsneed to be able to harmonize the rhythms of [[Honor]] and [[Cultivation]] in order to produce Towerlight.{{book ref|sa4|110}}
 
=== Nahel Bond ===
{{for|Order of Bondsmiths#Sibling Bondsmith Abilities|3=Order of Bondsmiths}}
The Sibling is one of the three great [[Bondsmith]] spren.{{book ref|sa4|3}} Forming a [[Nahel bond]] with them grants one the power over the [[Surge]]s of [[Tension]] and [[Adhesion]].{{file ref|TWoK Front Endsheet.jpg|Surgebinding Chart}} While a Bondsmith can use Adhesion the way a [[Windrunner]] would,{{book ref|sa3|28}} itthey can also apply their powers in different manner, using them more in the [[Spiritual Realm|Spiritual]]. Using Spiritual Adhesion, a Bondsmith can form a [[Connection]] between themselves and another person, allowing them to speak their language.{{book ref|sa3|65}} ItThey also seemsseem capable of hearing the spiritual aspects of objects and using this to mend broken things back whole.{{book ref|sa3|59}} [[Navani]] is able to assist the Sibling in once again making [[Towerlight]] in large enough quantities to fully restore the functioning of Urithiru.{{book ref|sa4|110}}
 
In order to bond with the Sibling, a person must be touching their crystal pillar.{{book ref|sa4|69}} The Sibling knows how to end the Nahel bond, and has done so in the past.{{book ref|sa4|87}} While the [[Nightwatcher]] and the [[Stormfather]] are known to be connected to [[Cultivation]] and [[Honor]] respectively, the Sibling is the child of both [[Honor]] and [[Cultivation]], created specifically to oppose [[Odium]].{{book ref|sa3|42}} The Stormfather considers all three of them to be "siblings", and the fact that they are the only three spren that can bond with Bondsmiths{{book ref|sa3|64}} indicates that they share some characteristics.

The Sibling is essentially the Tower of [[Urithiru]] and controlsby extension the manycomplicated fabrialsfabrial within.{{book ref|sa4|111}} ItThey isare capable of manifesting in the [[Physical Realm]] as both metal and as [[Polestone]]s. The Sibling can also fully power and control everythe various mechanisms of the fabrial that makes up the tower.{{book ref|sa4|112}} The temperature becomes warmer since heating fabrials become more potent, for example.{{book ref|sa4|116}} ​The Sibling is able to see everything within the tower.{{book ref|sa4|42}}{{book ref|sa4|111}} Their Bondsmith is also able to do so, as well as comprehend the mechanisms of Urithiru and speak through the veins of garnet in the tower as the Sibling does.{{book ref|sa4|113}}{{book ref|sa4|111}}
 
The red garnet vein within the wall strata serves as means of communication.{{book ref|sa4|39}} It can light up and, upon being touched, the Sibling will be able to mentally speak with a person or spren,{{book ref|sa4|55}}{{book ref|sa4|70}} although this can be eavesdropped through unknown methods.{{book ref|sa4|72}} This also allows people to communicate with each other if they are both touching the garnet vein.{{book ref|sa4|49}} The Sibling can also talk to people in weak mental state.{{book ref|sa4|49}} The line of garnet will give off a small amount of light when the Sibling wants it to.{{book ref|sa4|40}}{{book ref|sa4|89}} This can be moved within the garnet veins to guide people.{{book ref|sa4|42}}{{book ref|sa4|100}} The Sibling can open, close or lock the fabrial doors in Urithiru.{{book ref|sa4|55}} ItThey isare even able to key them to certain people.
 
The tower is very bright and due to the highly Invested nature of the tower, it glows brightly in the [[Cognitive Realm]], making it hard for people to see specific spren while there.{{book ref|sa4|39}}{{book ref|sa4|111}} Its highly Invested nature also makes it near impossible for the detection of kinetic Investiture.{{book ref|sa4|56}} [[Voidspren]] are unable to remain invisible while in the tower, though regular spren can.{{book ref|sa4|69}}{{book ref|sa4|58}} Previously, the outer halls of the tower were coated in [[aluminum]].{{book ref|sa4|37}}
 
; Without Towerlight:
When [[Ba-Ado-Mishram]] was imprisoned, the Sibling lost the [[rhythm]] of Towerlight, which stopped most of Urithiru from functioning.{{book ref|sa4|49}} In this state, the Sibling was only able to see patches of the tower and a small area around people who are Connected to them, mainly the [[Knights Radiant|Radiants]].{{book ref|sa4|42}}{{book ref|sa4|49}} Without hearing the correct rhythms, their Bondsmith would also be unable to produce Towerlight.{{book ref|sa4|69}} If the Sibling cannot generate Towerlight, itthey will be left open to be corrupted by [[Voidlight]] and [[Odium]]'s tone.{{book ref|sa4|49}}
 
Without Towerlight, most of the fabrials were dysfunctional.{{epigraph ref|sa3|68}}{{epigraph ref|sa3|69}} Functioning fabrial systems include those for increased pressure,{{epigraph ref|sa3|69}} temperature,{{book ref|sa3|53}} and general conditions encouraging plant growth.{{epigraph ref|sa3|69}} Navani also theorized that the air circulating through various shafts was powered by some sort of fabrial.{{epigraph ref|sa3|28}} In addition, the fabrial elevators connecting Urithiru's floors begin running when gemstones were inserted.{{book ref|sa3|8}} Basic suppression of Fused powers remained active.{{book ref|sa4|37}} Gemstones to open walls still worked if infused with Stormlight, though the Sibling could not keep certain people from opening it, only able to lock or unlock them.{{book ref|sa4|44}}{{book ref|sa4|55}}
=== Crystal Pillar ===
{{image|Navani's Notebook - The Crystal Pillar Room.jpg|side=right|width=250px}}
Deep inside the tower, there is a large monolith crystal pillar that serves as the Sibling's heart.{{book ref|sa4|111}} It is made of thousands of different gems.{{book ref|sa4|38}}{{book ref|sa3|30}} The pillar is where the Sibling is most exposed, and is where itthey can be bonded or corrupted.{{book ref|sa4|38}}{{book ref|sa4|69}} While functioning normally, the pillar glows the color of Towerlight.{{book ref|sa4|38}} If the Sibling is being corrupted with Voidlight, the color will darken.{{book ref|sa4|105}} The Voidlight and corruption can be pushed out by the rhythm of [[anti-Voidlight]].{{book ref|sa4|110}}
 
In order to protect the crystal pillar, [[Melishi]] created a bluesystem barrierof four sapphire fabrial nodes that canproduce surrounda itblue barrier around the pillar.{{book ref|sa4|40}}{{book ref|sa4|61}} This is done by giving four sapphire fabrial nodes hidden throughout the tower Stormlight.{{book ref|sa4|42}}{{book ref|sa4|5661}} The barrier is strong enough to stop humans, singers, and even [[Unmade]] from breaching it.{{book ref|sa4|42}} It even has a way of silencing itself to [[Fused]].{{book ref|sa4|56}} It can also be used to corrupt and unmake the Sibling remotely by infusing the nodes with Voidlight.{{book ref|sa4|42}} Since it was added later, the fabrial does not connect to the entirety of the tower and is powered by Stormlight instead of Towerlight.{{book ref|sa4|42}}{{book ref|sa4|56}}
 
The shield is made using the Surge of [[Surgebinding#Transformation|Transformation]]; [[Soulcasting]] air and persuading it that it is glass.{{book ref|sa4|49}} When attacked, the section of the shield will evaporate and will then restore itself almost immediately.{{book ref|sa4|61}} Each node is accompanied by a glass globe, wrapped in metal wires.{{book ref|sa4|59}} The globes have a reproduction of the crystal pillar room inside them, which helps the Soulcasting think the air around it is glass.{{book ref|sa4|61}} This makes the Soulcasting not a full transformation, but more of a half transformation. It needs a constant stream of Stormlight via the nodes to keep functioning, and takes in much more than a typical fabrial of its size.{{book ref|sa4|49}}{{book ref|sa4|42}} If a node is destroyed, the shield will weaken.{{book ref|sa4|40}} The more it is weakened and corrupted, the more its color goes from bright blue to dark violet.{{book ref|sa4|92}} If all four are destroyed, the shield will be destroyed.{{book ref|sa4|49}}{{book ref|sa4|105}}
