Cleansing of Shinovar

The cleansing of Shinovar is a mission undertaken by Kaladin and Szeth, accompanied by their spren and Nightblood. Their initial objectives were to to help Shinovar escape the influence of an Unmade who was believed to be there and to heal the Herald Ishar and seek his help with the upcoming Contest of champions. However, they later discovered that Ishar himself was in fact responsible for the dark influence on Shinovar. On the day of the contest, they succeeded in healing Ishar and removing his influence from Shinovar. This, in turn, allowed Ishar to reforge the Oathpact and induct Kaladin as a new Herald of Honor in Jezrien's place when Taravangian Ascended to Retribution, which enabled them to protect the Wind and the spren from Retribution.
== History ==
=== The Pilgrimage ===
Kaladin and Szeth would travel to Shinovar by flying along with the highstorm. Their goal was to cleanse it of an Unmade's influence, and heal Ishar, who was mentally unstable due to taking up part of the power of Odium. 
At the start of their quest, they encountered the Herald Ishar who challenged Szeth to complete a pilgrimage, a Shin religious ritual where a person would travel to each of the ten monasteries that were dedicated to each Herald and housed many of the Honorblades. 
Kaladin and Szeth first visited the Stoneward Monastery. Inside, Szeth found and fought the the Honorbearer Rit-daughter-Clutio. During the fight, Szeth restrained himself from using the Surge of Division at the order of his spren. Eventually, Szeth allowed Rit to entomb him in stone, and after finally being granted permission to use both of his surges, he utilized division to free himself and killed Rit. With Rit dead, Szeth was able to claim Talenel’s Honorblade and continue on. 
They then went to the Willshaper Monastery, where they found the Honorbearer, Sivi-daughter-Sivi dead having resisted the Unmade. They would claim her Blade and would leave. Throughout this time, Kaladin had been trying to help Szeth heal mentally, which Szeth's spren, 12124, did not like. The night after they visited the Willshaper monastery, Szeth would be brought to Shadesmar by the Elsecaller Honorbearer Pozen-son-Nash to fight him and the Edgedancer Honorbearer. As Szeth’s spren did not like Kaladin’s ideas, he would fetch the Herald Nale, who tried to cleanse Kaladin's influence of Szeth. 
After Nale’s arrival, they traveled towards the Lightweaver Monastery, where Szeth killed the Lightweaver Honorbearer, Moss-son-Farrier, and Kaladin killed the Truthwatcher Honorbearer who was trying to kill Szeth from behind. They then would visit the Truthwatcher Monastery as a formality and then visited the remaining monasteries, excluding the Windrunner Monastery, as the Honorblade there had been corrupted by Odium.
On the eighth day, the group arrived at the Dustbringer Monastery, where Szeth was tasked with fighting his sister Elid-daughter-Zeenid, the new Honorbearer. Instead of complying, Szeth chose to allow Elid the chance to kill him, which Elid did not take. Elid then revealed that the pilgrimage's real purpose was for Szeth to become a Herald, before dissolving into black smoke. Nale then intervened, telling Szeth that Ishar planned to use him to refound the Oathpact, and admitting that he was worried Elid would prove to be too weak.
The next day, Szeth and Kaladin arrived at the Skybreaker Monastery where Szeth encountered Nale, instead of an Honorbearer. Nale said that he would let Szeth go if he swore to become a Herald, which Szeth did not do. Nale then tried to kill Szeth which Kaladin stopped. Kaladin and Nale then fought. Kaladin did not do well in the fight until the Wind played the song that Kaladin had been playing the whole journey, the same one that had led the Heralds from Ashyn to Roshar. Kaladin then told Nale the story of the Derethil and the Wandersail, which made him end the fight and understand that the law was not perfect. Before they left the Skybreaker Monastery, Nale told them that they were not after an Unmade, but Ishar himself.
=== The Contest ===
On the tenth and final day, Kaladin, Szeth and Nale found Ishar, in the Bondsmith Monastery. They challenged him, but Ishar revealed his forces: the Honorbearers, brought back as human Fused, including Neturo. They attacked Szeth, beating him up, while Kaladin and Nale, as well as the Wind tried to reason with Ishar, to no avail. Throughout the fight Ishar had been telling Szeth to give in and obey. This caused Szeth, tired of obeying orders, to swore the Fifth Ideal becoming the law and dismissed 12124, breaking the bond. Szeth would then try to use Nightblood to destroy the Honorbearers.
Intimidated, the Honorbearers backed away. Ishar then Connected himself to Szeth and Kaladin, allowing them to feel the Heralds' pain, crippling them. But, Kaladin stood, and swore the Fifth Ideal, while still Connected to Ishar, which healed him. Kaladin Connected to Nightblood allowing it to feed on his Stormlight while Szeth wielded it, which allowed Szeth to use the Surges and he attacked the Honorbearers, killing them permanently. 
However, after burning through all of Kaladin’s stormlight Nightblood threatened to consume them all, until Kaladin reasoned with it enough to stop destroying evil. Szeth was knocked unconscious after losing an arm to Nightblood.
==== The Oathpact Reforged ====
Ishar realized that the Oathpact must be reforged, in order to protect the spren from Retribution, and had discovered a way to do so, linking the Heralds to a vision in the Spiritual Realm in between Desolations. Kaladin agreed to become a Herald in the place of Jezrien, and was made immortal. The other remaining Heralds, Taln, Shalash, Vedel, Battar, Chanarach, Kalak, Pralla, came there, healed and reforged the Oathpact, returning to the Spiritual Realm with Syl.
=== The Aftermath ===
Szeth eventually awake and found Kaladin's mortal body dead, his soul in the Spiritual Realm, and buried it with the help of Marsha-daughter-Shaliv, his future wife. The day came to be known as Stormfall, years later, specifically in the book Knights of Wind and Truth.
