Fourth Brother

"I feel an unease in the Force. What if everything that we've been taught to believe in is a lie? I sense you feel it as well." "War breeds confusion. We must hold such teachings close to our hearts. There will be times that we will have to fight. But, Master Yoda tells us to believe in the Force. I understand you're confliction, but you will soon realize that you're going down the right path."

- Yarv Lask and Ki-Adi-Mundi, on their mission to Bastion

The Fourth Brother, formerly known as Yarv Lask, was a Force-sensitive Iridonian Zabrak male who served in the Inquisitorius during the reign of the Galactic Empire. Prior to his fall to the dark side of the Force, Lask held the rank of Jedi Knight and was amongst the greatest lightsaber duelist in the Jedi Order. Following the outbreak of the Clone Wars, his faith in the Jedi as peacekeepers conflicted with their new responsibilities as generals in the armed forces of the Galactic Republic. Early in the war, Lask was sent on a mission to the planet Bastion with a squad led by Jedi Master Ki-Adi-Mundi. After returning to the Jedi Temple on Coruscant, Lask was put on trial by Grand Master Yoda and the Jedi High Council for attempting to kill Mundi. However at Mundi's request, Lask was spared from the death penalty and was exiled from the Jedi Order.

In the aftermath of the Great Jedi Purge, Lask joined the ranks of the Inquisitorius as the Fourth Brother. He was tasked with hunting down two Jedi survivors of Order 66, Jedi Master Del Morrigan and Jedi Knight Main Character. The Fourth Brother tracked the fugitives to the planet Batuu, where they lived in hiding for years, but Morrigan and TBD managed to escape the Inquisitor. As a result, the Fourth Brother was accompanied by the Fifth Sister and later the Second Brother to hunt down the two Jedi across the galaxy.

Mission to Bastion
Following the First Battle of Geonosis, the Jedi High Council sought to discover the truth behind the Separatist operation on the planet Bastion. As a result, the Jedi Council sent Jedi Master Ki-Adi-Mundi and his squad to Bastion. While assembling the special team for the mission, Yarv Lask was chosen by Mundi, who admired the Jedi Knight and his impressive skill with a lightsaber. Mundi felt that Lask would be a great addition to his squad as they began to go on missions at the request of the Jedi Council. Mundi also chose Jedi Master Saesee Tiin, Jedi Master Kit Fisto and Jedi Master Adi Gallia to be on his team.

After arriving on Bastion, Lask confided in Mundi his feeling of unease in the Force as well as his belief that the teachings and beliefs of the Jedi Order were being tested, to which Mundi concurred. When they arrived, they noticed a group of battle droids patrolling the area. Mundi commanded the squad to split up and take out the droids. They immediately began attacking the droids with Lask jumping on an Octuptarra tri-droid, cutting it in half. A couple of B2-series super battle droids attempted to catch him off guard and kill him. Fisto and Tiin came from behind and cut the droids down. The squad continued to push through the droids on patrol before continuing on their mission. As they walked down the jungles, Lask pointed out large clouds of smoke in the air and loud noises. The smoke and noise led them to an open field with ore crawlers stripping the planet's surface with more battle droids guarding the area.

Lask and the others believed that the Separatists were on Bastion to mine ore from the surface. Mundi told Lask and Gallia to start taking out the droids on guard. Mundi took Tiin and Fisto to hijack and destroy the ore crawlers. Lask accompanied Gallia in taking out the remaining droids that were commanded by TL-95. As they managed to push back the Separatist defenses, TL-95 ordered his troops to retreat. Lask and Gallia caught up to TL-95, but before they could destroy the tactical droid he told them that he would kill the captives in the ore crawlers. Lask became hostile and demanded an explanation about the captives that were mentioned, but Gallia tried to keep him calm and advised him to trust in the others to make the right decision. Lask disregarded her wisdom and cut down TL-95 while letting the remaining droids escape.

Confronting Mundi
After reuniting with Mundi and the others, Lask confronted Mundi about captives on the ore crawlers they just destroyed. Mundi assured him that there were no prisoners in any of the machines. He accused Mundi of lying for the sake of their victory over the Separatists and proceeded to grow hostile towards Mundi, who refused to entertain Lask's claims. Lask then ignited his lightsaber, intending to kill Mindu out of frustration. Although he felt responsible for failing Lask, Mundi activated his own lightsaber in order to defend himself, resulting in a duel between the two Jedi.

As they fought, Mundi beseeched Lask to cease his attack by reminding him that they were both walking down the path of the Jedi. Lask rejected all of his words as lies and declared his intent was to no longer serve the Jedi Order and follow his own path. The duel pressed on until Mundi Force pushed Lask to the ground and deprived him of his lightsaber. After a moment of contemplation, Mundi decided that the Jedi Council should determine Lask's fate and therefore arrested him. Leaving him confined in the T-6 shuttle they arrived in, the rest of the squad proceeded to complete their mission.

Trail before the Jedi High Council
A shackled Yarv Lask was brought back to the Jedi Temple on Coruscant and placed on trial for turning against his team and attacking Mundi. The Jedi Council accused him of heresy and insubordination, but Lask refused to find fault in his actions and further expressed his belief that the war had changed the Jedi. Ultimately, he was found guilty of treason, and though he expected to be put to death, Mindu implored his colleagues to be merciful. Mundi knew that Lask would refuse to stay in the Jedi Order for rehabilitation, so Mindu granted Lask's wish of following his own path outside of the Order. The Jedi Council agreed to Lask being exiled from the Jedi Order.

Fall to the dark side
At the end of the Clone Wars, the Jedi Order was all but wiped out by Order 66, a contingency order implanted into the clone troopers that ordered the deaths of all Jedi. Coinciding these events, the Galactic Republic was replaced by the Galactic Empire, who sought to hunt all of the remaining Jedi. Lask fell to the dark side of the Force and eventually joined the Inquisitorius, becoming the Inquisitor known as the Fourth Brother.

Hunting Jedi
In 9 BBY, the Fourth Brother traveled to the planet Batuu with the Fifth Sister and some Purge Troopers in search of possible Jedi.

Personality and traits
Yarv Lask was an average sized Iridonian Zabrak male with light tan skin, brown eyes and Iridonian facial tattoos. Lask believed that the Jedi could use their abilities and power to serve the galaxy as peacekeepers until they were made soldiers for the Republic Military. During a mission on the planet Bastion, Lask's doubts about the Jedi were reassured as he thought Jedi Master Ki-Adi-Mundi destroyed ore crawlers with prisoners still inside. Eventually, his confliction turned into anger which led him to confront Mundi, intending to kill him.

When Lask fell to the dark side of the Force, his hatred for the Jedi only worsened as he was willing to hunt down all Jedi survivors for the Empire. He was an exceptionally cunning and intelligent individual able to manipulate almost any adversary into revealing their weakness and fears.

Powers and abilities
Yarv Lask was an expert lightsaber duelist that was proficient in multiple Force powers to gain an advantage over his enemies. Although he was able to hold his own against Ki-Adi-Mundi during their duel, he was ultimately bested and disarmed. Following his fall to the dark side of the Force, he was able to throw his lightsaber with deadly precision. He fought with agility and finesse, often using Force Dash and Force jump to quickly evade his attacker. His fighting style was also full of rage and aggression, taking out his anger on the Jedi. The Fourth Brother also possessed impressive telekinetic abilities, such as Force push, Force choke, Force repulse and Force Stasis.

Equipment
During his time in the Jedi Order, Yarv Lask used a green single-bladed lightsaber. He wore brown Jedi robes with a cloak and boots. During his time as an Inquisitor, the Fourth Brother used a red double-bladed spinning lightsaber. He wore a personalized version of the black and gray Inquisitor garbs. He outfitted his uniform with a few dark plates of armor, with the Imperial crest in white on the shoulder plates, and black boots.
