Jaran Kareel was a powerful Force-sensitive Adien male Jedi Knight who fought in the Clone Wars and survived in exile during the Great Jedi Purge. Jaran was also the sole descendant of the great Jedi Master Jal'kai Kareel, who had lived nearly three thousand years before. As a boy, he was found by Jedi Master Kit Fisto on the run after leaving the planet Tyos prior to the destruction of his home. Upon being inducted into the Order, he was placed under the tutelage of the noble and experienced Kiffur Jedi Knight Callista Konshi. During the war he grew close to his peers, especially a female togruta Jedi named Sheya Tisa, whom he had a secret relationship with.

His campaigns warped him into a war hero and he became a legend across the galaxy. Although Anakin Skywalker remained the poster boy for the Clone Wars, Jacius was known as the "Hero with Courage" and became very famous among the citizens of the Republic. He spent years commanding the 30th Assault Legion with Clone Commander Trigg, winning many battles that made him as legendary as he was. At the pinnacle of the war, he had earned a reputation as one of the deadliest threats to the Confederacy of the Independent Systems, and was a constant target for the plans of General Grevious and Count Dooku. He visited Sheya as often as he could in between missions, but was oblivious to the knowledge that she had become pregnant with their child.

At one point in the war, he was captured by the dark acolyte Oran Teithis, and was taken to Dromund Kaas to be a vessel for the returned spirit of the ancient Sith Lord, Darth Crimsonis, a sworn enemy of Jaran's family line. The incident on the planet would affect him for years to come. In a desperate attempt to save their friend, Jacius's companions came to rescue him. After Sheya and Trigg brought Jacius back to the lightside, Sheya was killed at the hands of Oron Teithis in his thrist for revenge on Jacius. However, Jacius avenged her by killing Oron Teithis shortly afterward. Upon her death, she told Jacius of their daughter, named Jey'sha, and of her love for him before passing to the living Force.

Upon the execution of Order 66, Trigg allowed Jacius to flee after Callista was shot down by her own troops. For the next twenty years, Jacius raised his daughter in exile and gave her the saber of her mother. But in secret, Jacius would hunt down and kill Imperial Officers who had knowledge of Palpatine's plans. He became known as the "Crimson Knight" for slaughtering the officers with a red lightsaber. His descent to the Dark Side and personal crusades made him a feared figure across the Empire, and was openly known to oppose Darth Vader and the Emperor. He briefly met the mandalorian Cassus Hunter to achieve his goals, and took up a job as a Mandalorian bounty hunter, a homage to the culture of his troops during the Clone Wars.

At the start of the Galactic Civil War, Jacius was confronted by Obi-Wan Kenobi and was redeemed. He then spent the remainder of his time aiding the Rebel Alliance in restoring the Repbulic. He would eventually go back to retake the Jedi Temple with a contingency of surviving Jedi from the Purge and rebuild the Jedi Order. He taught many generation alongside the Jedi Master Luke Skywalker afterwards before he passed away to join the living Force, reunited with Sheya and his fellow Jedi.
