Vienta

Vienta is an honorspren on Roshar. She bonded with Sigzil during the True Desolation and their bond was broken before the Night of Sorrows.
== Appearance and Personality == 
In the physical realm, Vienta takes the form of a small woman shrouded in flowing robes that drift around her, the only body part visible being her eyes. When she is pleased, she can "fuzz", blurring herself. Her mind is sharp as a nail, giving complex calculations to Sigzil quickly. She prefers to remain invisible compared to other honorspren and is shy compared to others such as Syl or Phendorana..
Vienta has a very analytical mind; she is able to find distance and momentum at a glance and can solve math problems quickly. This allows her to give data to Sigzil almost instantly that would usually take time for a human to process, or give information relevant to the topic at hand that others have told them. Other honorspren have made fun of her for this in the past, with Syl saying she's more similar to a Cryptic spren. It is especially useful during the heat of battle, such as figuring out how to kill a new variant of Fused. She can notice subtle changes and notify Sigzil, such as an increase in lightning strikes per minute. She would prefer people not to know it was her doing all of these complex things rather than Sigzil, but Sigzil thinks it's amazing.
== Attributes and Abilities ==
Like other honorspren, Vienta is a Splinter of Honor. She has minimal substance in the Physical Realm, and glows with a blue-white light. She can choose to be invisible or visible to humans, and most often chooses the latter, although some humans can still see them, such as Lunamor.
She is also able to form a Nahel bond, increasing her sentience in the Physical Realm and granting a bonded human abilities of the Order of Windrunners, including the Surges of Adhesion and Gravitation. She can speak directly into the mind of her bonded Radiant. She often appears as a Shardspear, but can alternatively be a lance.
== History ==
At some point, Vienta is bonded by Sigzil, to at least the Fourth Ideal.
=== Siege of Narak ===
Sigzil, along with Vienta, was sent to the Shattered Plains on the fourth day to defend it before the borders froze when the Contest of Champions started. Sigzil's plan revolved around getting the Fused to attack specific plateaus out of the four they have access to and getting them to attack their weak points intentionally to waste the attackers' time. First they made Narak Four's bridge weak, attempting to goad the enemy into attacking it. They attacked with a new, unseen brand of Fused, Focused Ones, and the thunderclast Kai-garnis. During the battle, killing the new Focused Ones proved to be a difficult task to figure out as any weapon would be unable to get deep enough into their thick skin. Vienta gave Sigzil the data he needed after fighting one for some time, telling him to use four Lashings in quick succession. This allowed him to gain enough speed to puncture and kill one. After the battle, the two leave to discover that reinforcements of Heavenly Ones have been sent using Dai-Gonarthis, with Moash in the fray. 
On the sixth day, Sigzil's squire, Deti, dies during a battle. He lets loose, killing many Regals, but Vienta warns him to regroup his forces and retreat and that he can't bring Deti back. After the Coalition forces retreat, Narak Four is taken over by the enemy. Sigzil makes sure Bridge Four members are on the lookout for Moash. 
The strategy now that Narak Four had fallen was to divert attention to Narak Three instead, casting an illusion of a full Stormlight cache to encourage the enemy to attack it as a way to demoralize the Coalition. When Sigzil asked, Vienta thinks it unlikely they will survive the three days, given the limited supply of Stormlight. Initially, the enemy attacked Narak Prime, attempting to overwhelm it, but after viewing the illusion the Lightweavers put up, pivoted their forces to attack Narak Three. Moash then appears on the battlefield, and tricks Leyten and Sigzil with a hidden anti-Stormlight device, and after Vienta realizes Moash can see them with his new crystal spikes, he kills Ethenia, Leyten's spren, with an anti-Stormlight knife, then stabs Leyten. Later, Sigzil worries about Leyten's death rattle predicting him and Vienta's death, while Ethenia's death has a big effect on Vienta, and she is worried the same may happen to her. 
Later, after discussing their retreat with the Stormwall and Demi, he is surprise attacked by Moash, using a rare Anti-Stormlight device that causes Sigzil to fall from the sky; he also realizes Vienta is visible to Moash's hemalurgic crystal eyes. When Moash moved to strike Vienta, Sigzil renounced his oaths as a Windrunner. Vienta was now a deadeye, her sword appearing in the Physical Realm shortly after. Moash then retreats after several Bridge Four members show up, such as Lopen, but Sigzil is still crushed by the emotional impact of breaking a bond.
=== After the Night of Sorrows ===
Vienta was the first spren that Sigzil sought out after being trapped in Shadesmar when Wit transferred him there after accepting the Dawnshard. She was healed by what happened at the End of All Things. She refused to see him, instead sending him a message, but Sigzil didn't blame her.
== Relationships ==
=== Sigzil ===
Both Sigzil and Vienta are very scholar-like. Sigzil thinks Vienta's sharp mind is brilliant, despite how other honorspren teased her for it. Vienta can offer all kinds of information in meetings or battle, ranging from a tidbit the Heralds mentioned about how many Fused there are, to the amount of lashings required to pierce a Focused One. After their bond was broken, Vienta did not wish to see him but understood why he did it.
